5 Methods & Types of Pipe Bends

March 17, 2023
Metal pipes on the side of the staircase.

Bending is a fundamental process in the metal fabrication industry, used to create a range of products, from simple household items to complex aerospace components. Different types of bending methods are used depending on the material, the shape of the desired product, and the degree of precision required.

Understanding the different bending methods available can help you select the most appropriate method for your specific application. In this blog, the team at VeriForm Inc. explores some of the most common bending methods used in the industry and the types of bends they produce.

Compression Bending

Compression bending involves the use of hydraulic pressure to deform a section of the pipe and form a bend. This process is commonly used in industrial applications to create bent pipes for various uses, such as in pipelines, plumbing systems, or HVAC systems.

The compression bending process typically involves placing the pipe into a bending machine consisting of a bending die and a counter die. The bending die is designed to deform the pipe into the desired shape, while the counter die supports the pipe and prevents it from collapsing during the bending process.

The machine applies hydraulic pressure to the pipe to compress it against the bending die, causing it to bend gradually to the desired angle. The pressure is then released, and the pipe is removed from the machine.

Compression pipe bending can be used to create bends of various angles and radii, depending on the specific needs of the application. The method is preferred over other bending techniques for thick-walled or heavy pipes, as it can produce high-quality bends with minimal distortion or deformation.

Rotary Draw Bending

Rotary draw bending is used to create precise and consistent bends. In this process, a mandrel is inserted into the tube or pipe to prevent it from collapsing or wrinkling during the bending process. The tube or pipe is then clamped onto a die, and a rotary draw bending machine is used to rotate the die while pulling the tube or pipe around the die to create the desired bend.

The bending process is controlled by a computerized program that ensures the tube or pipe is bent to the correct angle and radius, resulting in accurate and repeatable bends. For this reason, it is a preferred method for metal pipe and tube bending.

Rotary draw bending is commonly used in the automotive, aerospace, and industrial manufacturing industries to create a variety of products, such as exhaust systems, roll cages, and frames.

Roll Bending

Roll bending forms a metal sheet or plate into a curved shape by passing it through a set of three or more rollers. The rollers are arranged in a pyramid shape and rotate around their respective axes, and the metal sheet or plate is passed between them in a series of incremental steps until the desired curvature is achieved.

Roll bending is commonly used in the fabrication of pipes, tubes, and other cylindrical or curved shapes and can be performed using either a pyramid-style machine or a three-roll machine. The process can be used with a variety of materials, including steel, aluminum, and copper, and can produce a range of curves, including tight radii and gradual curves. It is a highly precise and efficient process that can produce consistent results with minimal waste, making it a popular choice for industrial manufacturing applications.

Mandrel Tube Bending

Mandrel tube bending is used to bend pipes or tubes without collapsing or wrinkling the walls of the tube. The process uses a mandrel, which is a solid steel rod or shaft, to support the inside of the tube while it is being bent. This prevents it from collapsing or wrinkling during the bending process.

Before the bending process begins, the mandrel is inserted into the tube. As the tube bends, the mandrel remains stationary and supports the inner radius. This keeps the tube from collapsing or wrinkling on the inside of the bend.

Mandrel tube bending is used in a wide variety of industries, including automotive, aerospace, and construction. It is often used to create complex or custom shapes in tubes or pipes, such as exhaust systems or roll cages. The process can be performed using manual or CNC-controlled tube bending machines.

Press Bending

In press bending, metal sheets are bent using a press brake machine. A flatbed and a top tool move downward to apply force to the metal sheets. After the metal sheet is placed on the flatbed, the top tool is lowered onto it to bend it.

Press bending can be used to create a wide range of shapes, including V-shaped, U-shaped, and channel-shaped bends. It is commonly used in the manufacturing of parts for various industries, including automotive, aerospace, and construction. It can also be used on a variety of materials, including steel, aluminum, and other metals.

What Are The Different Types of Pipe Bends?

The bending methods described above can be used to shape a wide range of pipes. They include but may not be limited to:

●     Long Radius Bend: A long radius bend has a centerline radius that is equal to 1.5 times the pipe diameter. This type of bend is used in low-pressure and low-velocity applications where there is a need for minimum pressure drop.

●     Short Radius Bend: A short radius bend has a centerline radius that is equal to the pipe diameter. This type of bend is used in high-pressure and high-velocity applications where there is a need for maximum pressure drop.

●     3D Bend: A 3D bend has a centerline radius that is equal to three times the pipe diameter. This type of bend is used when space is limited, and there is a need for a tight bend radius.

●     5D Bend: A 5D bend has a centerline radius that is equal to five times the pipe diameter. This type of bend is used in applications where there is a need for a larger bend radius.

●     10D Bend: A 10D bend has a centerline radius that is equal to ten times the pipe diameter. This type of bend is used in applications where there is a need for a very large bend radius.

●     Mitered Bend: A mitered bend is a custom bend that is fabricated from straight pipe sections. It is used when a specific angle is required that is not available in standard pipe fittings.

The choice of pipe bend type depends on various factors such as the budget, application, space limitations, pressure, and flow rate of the fluid being transported.

5 Best Types of Steel Staircase Designs

February 28, 2023
Spiral Steel staircase.

Steel staircases have several advantages. They’re sustainable, low-maintenance, and easy to customize. For these reasons, they’re in demand in all kinds of locations, from homes and offices to factories and industrial facilities. 

Choosing the best steel staircase design can be daunting, especially with so many available options. That’s why the experienced team at VeriForm Inc. created this blog to help you explore the five best types of steel stairs and their unique features. 

Where Are Steel Staircases Installed?

Steel staircases are versatile and can be installed in a variety of settings, both indoor and outdoor. Here are some of the more common places to encounter them:

  • Commercial Buildings: Steel staircases are commonly used in commercial buildings such as offices, hospitals, schools, and shopping malls. They provide a durable and long-lasting solution for high-traffic areas and can be designed to comply with safety codes and regulations.
  • Industrial Facilities: These staircases are also used in industrial facilities such as factories and warehouses. They provide a safe and sturdy access point to mezzanines, platforms, and other elevated areas.
  • Residential Buildings: Contemporary and industrial-style homes increasingly feature steel staircases. They provide a sleek, minimalist look and can be customized to fit any space.
  • Outdoor Spaces: Outdoor spaces such as parks, stadiums, and public spaces can also be fitted with steel staircases. They are weather-resistant and can be designed to withstand extreme conditions.

What Are The Best Types of Steel Stairs?

Are you having trouble deciding on a staircase style for your facility? Here are some of the best types of steel stairs in use today. 

Straight Steel Staircase

For a steel staircase, this is the most common and straightforward design. It consists of a single flight of straight stairs that goes from one level to another without any turns, making it a perfect option for homes and buildings with limited space. The steps can have closed or open risers, and they can be designed with or without a landing, depending on the height of the space and the desired look and functionality.

One of the benefits of a straight staircase is that it is easy to navigate. Additionally, it can be more cost-effective than other types of staircases, as it requires less complex design and construction. However, straight stairs can take up more floor space than other types of staircases and may not be suitable for small or narrow spaces.

Spiral Steel Staircase

A spiral staircase consists of a central post or column around which the steps wind in a spiral pattern. They are often used in small or narrow spaces where a traditional straight staircase may not fit. They can also serve as a striking architectural feature, adding a touch of elegance and sophistication to any space.

Spiral staircases can have open risers or closed risers and can be designed to turn clockwise or counterclockwise. The steps can be wide or narrow, and the handrail can be made of various materials such as metal or wood.

Floating Steel Staircase

A floating steel staircase is an ultra-modern design that creates the illusion of floating stairs. Unlike traditional staircases, which rely on a visible structural support system such as a stringer or a central beam, floating staircases are designed to be self-supporting, with each step attached to a hidden support structure within the wall or the staircase itself.

These unique steel staircases can be straight, curved, or angled and can feature open risers or closed risers. The steps themselves can be thick or thin and can be designed with various edge profiles. However, they may require a higher level of structural engineering than traditional staircases and may be more expensive to install.

L-Shaped Steel Staircase

An L-shaped staircase changes direction at a landing. It typically consists of two flights of stairs connected by a 90-degree turn. One flight goes up a certain number of steps, and then the other flight begins at a landing and goes in a perpendicular direction. The landing in between the two flights of stairs can be either a small platform or a larger area that allows for a turn and rest. L-shaped steel staircases provide an elegant and practical solution for changing elevations while taking up less floor space than a straight staircase.

L-staircase. A set of stairs are connected perpendicular to each other.

U-Shaped Steel Staircase

A U-shaped staircase consists of two parallel flights of stairs connected by a landing at the bottom and/or top, creating a U-shape in plan view. The stairs are typically wider than those in a straight or L-shaped staircase, which allows for a more spacious feel and greater traffic flow. They also provide a continuous handrail, which can improve safety and accessibility. The landing in the middle of the staircase can serve as a natural pause point or gathering spot.

Overall, a U-shaped staircase can be a stunning architectural feature that adds both style and functionality to a space. However, they do require careful planning and installation to ensure proper structural support and safety.

What is the Best Metal for Fabricating Steel Staircases?

There are many factors to consider when choosing the best metal for stairs, including the specific application, design requirements, durability, and maintenance requirements. These are some of the common types of metal used for stairs:

  • Aluminum: Aluminum is a lightweight and corrosion-resistant metal that is easy to maintain and can be finished with various colours and textures. However, aluminum may not be as strong as steel and may require additional support for heavy traffic.
  • Steel: Steel is a popular choice for stairs due to its strength, durability, and versatility. It can be shaped and welded to create different designs and can be finished with various coatings to prevent corrosion and wear.
  • Stainless Steel: Stainless steel is a corrosion-resistant, low-maintenance metal that provides a modern, sleek look. However, stainless steel can be expensive and may require more maintenance to keep its shine.
  • Bronze: Bronze is a durable, corrosion-resistant metal with a classic, elegant look. It can be shaped and finished to create intricate designs but may require more maintenance to prevent tarnishing.

Ultimately, the best metal for stairs will depend on the project’s specific requirements, including the design, location, and budget. It’s best to consult with a professional to determine the best metal for your particular needs.

How to Estimate Steel Fabrication Cost

February 17, 2023

In the metal fabrication industry, knowing how to accurately estimate steel fabrication cost is critical to satisfying customers and protecting your profit margins. While it’s not too difficult to come up with an estimate for time and materials, they are only part of the equation.

Steel fabrication projects come with associated costs – the design, prototyping, finishing processes, etc. To get the most out of your project while keeping clients satisfied, you need to have a cost-saving plan. The following tips, which have been compiled by the experienced team at VeriForm Inc., will help you strengthen your job costing and maximize profits and resources.

Cost Estimation of Steel Products- Getting Started

In today’s competitive markets, it is important to have a clear understanding of cost structure before developing a pricing strategy. The sheet metal production cycle includes bending, forming, punching, welding, and many more phases, each with its own associated costs. 

To start, break down the production cycle into more straightforward processes, so you can focus on one process at a time. Then follow the steps below to get an accurate estimate of the costs involved.

Prepare a Raw Material Cost Calculation

You’ll need to estimate the number of raw materials needed to complete a single product associated with the project. Use the following steel fabrication cost calculator to estimate the material cost per product piece:

Raw material cost= volume x density of material x cost of material per kilo

If you’re purchasing steel with a density of 7.4kg/dm3 at $0.8 per kilo and the plate dimensions are 700x300mm with a 1mm thickness, you’re looking at a raw material cost of $1.29. See the calculations below:

(7 x 3 x 0.01) x 7.4 x 0.8 = 1.29

This process must be repeated for each raw material.

Calculate the Machining Cost

At this point, you must know the hourly cost, efficiency, and cycle time (productivity) of the machines being used. To calculate this information, use the formula below:

Machining cost= (hourly cost x cycle time for single piece) / efficiency

If the cycle time is 10 seconds with an 87% efficiency and hourly cost of $77.30, this formula will yield the following information: 

(77.30 x 10) / (0.87 x 3600)

Machining Cost = (78.4 x 12) / (0.855 x 3600), which yields a total of $0.24. 

To get the total production cost for a single fabricated piece, combine the cost of your raw material with the machining cost. Using the figures above, this would be:

$1.29 + 0.24 = $1.53

These calculations can give you a reasonable idea of your costs during this particular machining aspect of the production cycle.

Calculate Costs For The Different Phases of Production

Now that you have the production cost for one machine, you can apply the same cost calculator for other machines or phases. This way, you’ll get an accurate idea of your steel fabrication costs from the moment production begins until the product is ready for delivery.

Factors That Affect the Cost of Steel Fabrication

In this section, we’ll discuss some of the different factors that may influence the cost of metal fabrication for your project.

Raw Material Costs

Raw materials often fluctuate in price, causing steel fabrication costs to vary. Other factors related to raw material cost include:

  • Transportation (the closer your facility is to the source, the lower this cost will be)
  • Metal thickness
  • Requirement for multiple materials
  • Supply chain disruption

Plating and Welding Costs

When sheet metal arrives pre-plated, welding is risky because the coating can release zinc oxide when heated. If you go with uncoated steel, you’ll want to coat it after fabrication to make it more corrosion-resistant. This added step increases both cost and lead time.

Work Required

The amount of physical work required to complete the metal fabrication process will dictate the number of workers needed, which affects labour costs. Some applications, such as the use of CAD/CAM software, call for expert skills that typically cost more.

Metal Structure Qualities

The design complexity of the metal structure will affect the cost of fabrication. For example:

  • A project with fewer bends, cuts, and welds will cost less.
  • Intricate designs and tight tolerances often require longer manufacturing times and incur higher labour costs.

Tips for Reducing Steel Fabrication Costs

There are ways to reduce steel fabrication costs without impacting the integrity of your project.

  • Using Standard Metal Sizes and Gauges: Standard sheet sizes are often less expensive than special-length sheets. Selecting material grades based on present market conditions can help minimize costs associated with variable gauges.
  • Strategic Material Selection: Raw materials affect sheet metal fabrication costs. Use stock sizes whenever possible and choose less expensive materials for prototypes. You can also reduce costs by buying mill-direct.
  • Lower-Cost Finishing Options: A special finish may require cost estimators to obtain external quotes, adding to the price and lead time. Some standard finishes are less expensive and faster to obtain. Finishes such as chrome plating and powder coating are readily available at a minimal cost.
  • Contact a Professional Steel Fabricator: A fabrication company capable of handling most of the process on its own can speed up production and deliver products of the highest quality while helping to save costs in the long run. By connecting with a reputable steel fabricator, you can get the products you need at a competitive rate.

VeriForm Inc.: Your Steel Fabricating Experts

One of the factors to consider when designing sheet metal parts is fabrication costs. If you follow the tips discussed above, you can effectively control and even reduce the cost of steel fabrication.

What is Structural Steel Fabrication?

January 30, 2023

Structural steel fabrication is the process of cutting, bending, and shaping steel components for later use in steel structures like buildings, towers, and bridges. The various steps involved, which include the use of complex fabrication technologies, often call for equal measures of experience, skill, and artistry. 

Structural steel fabricating is a specialty skill that requires experience in converting raw materials into products that meet applicable codes and standards. It is widely used in the following industries:

  • Aerospace
  • Automotive
  • Construction
  • Energy
  • Manufacturing
  • Mining
  • Shipbuilding

At VeriForm Inc, our structural steel fabrication services are provided by highly skilled tradespeople and state-of-the-art equipment. In this article, we’ll explain what structural steel fabrication is, what it’s used for, and how a top-rated Ontario metal fabrication company can help you get quality results. 

What is the Most Commonly Used Structural Steel?

Steel’s chemical composition and the treatments it undergoes can affect its hardness and ductility, making different types of steel suitable for specific applications. We’ll discuss the three main types of structural steel below.

Carbon Steel

For structural applications, carbon steel is a popular choice. As a matter of fact, it is the most commonly produced steel in North America. Carbon steel is both strong and ductile (it can bend into any shape without breaking), and it is also relatively easy to manufacture. 

This structural steel is an alloy, which means that it’s mixed with other metals or non-metallic materials. The main constituents of carbon steel are iron and carbon, with a few other elements alloyed in very small amounts. It is made in a blast furnace by mixing iron with coke (an industrial fuel made from coal or oil). The steel is cast into a mold after undergoing additional processes such as deoxidation. After that, it can be rolled, cold-formed, or heated to create the exact steel you require.

Since carbon steel is so common, it can be used for a wide variety of purposes, from bridges and buildings to bolts and fasteners. Nonetheless, other forms of steel are also suitable for specific applications.

Tool Steel

Steel alloys become stronger and harder when they are quenched and tempered. The first step is to quench alloy steel. In other words, it is heated up to a critical temperature and then cooled down immediately. (To prevent brittle edges on the steel, this process must be tightly controlled.) Following quenching for extra toughness, the alloy will be tempered. In tempering, the metal is heated once more, but below its critical point. It is then air-cooled. 

Alloy steel that has been quenched and tempered can be used for many things, including building bridges and skyscrapers. It is also used for making tools, which is why it is called tool steel.

HSLA Steel

The term HSLA refers to high-strength low-alloy steel. Elements like manganese, copper, nickel, zirconium, or more are added to steel to make it harder. Steel was originally designed for pipelines, but now you can find it in cars, cranes, and even roller coasters. Since HSLA has a good strength-to-weight ratio and can withstand a lot of stress, it is an ideal building material.

This steel also tends to be more corrosion-resistant than other kinds due to the particular elements alloyed into it. It is, however, more difficult to manufacture than carbon steel.

What Happens During Structural Steel Fabrication?

Structural steel fabrication is a multi-step process that starts with cutting and bending and usually progresses to welding and assembly.

Structural Steel Cutting

Fabricators cut structural steel using a variety of methods that include:

  • Oxygen-Acetylene Flame Cutting: This technique is commonly used for general cutting or edge preparation, such as beveling, coping, or notching.
  • Plasma Cutting: This mechanically-guided process is often used to cut steel plates up to one inch thick.
  • Laser Cutting: Like plasma cutting, this process is useful for cutting steel plates.
  • Water Jet Cutting: This manufacturing process uses high-pressure water jets to cut and shape various types of materials.
  • Shearing: Performed with mechanical presses, shearing is generally useful for cutting plates and angles.

Structural Steel Bending or Rolling

The next step is to bend or roll the alloy. The process of rolling or bending structural steel involves curving it to a specified radius and arc length. The term bending generally refers to creating a bend with a tighter radius, while rolling describes a bend with a larger radius. Bent and rolled steel are often used in environments that require a curved aesthetic, such as domes, arenas, canopies, and roof trusses.

A steel fabricator can hammer steel manually or with a machine. Whether you should do one or the other depends on how much repetitive bending your project requires. Fabricators are more likely to use machinery if bending structural steel is highly repetitive.

Structural Steel Assembly

Combining the various steel parts is the next step in creating steel structures. Although some structures call for the pieces of steel to be joined using rivets, welding is the most commonly used option. This is because welding can make the steel stronger, preparing it for high-pressure applications like I-beams or columns. Compared to riveting, welding gives structures greater strength and durability.

Cleaning and Painting

The last step of the process is to clean the structure surface of any debris. The surface is prepared for painting by using a variety of cleaning methods, such as surface rusting, blasting, etc. Generally, steel structures are painted with two layers of normal paint and one layer of anti-rust paint, which protects against corrosion caused by environmental factors.

Applications of TIG Welding: Analysis of Advantages & Disadvantages

January 18, 2023
Applications of TIG Welding blog featured image. Worker with full protection gear welding a door frame using TIG welding.

Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW) is a form of arc welding that uses a non-consumable tungsten electrode to create the weld. Due to their high performance, strength, and reliability, GTAW welds are commonly used in aerospace and nuclear energy.

In the 1940s, TIG welding skyrocketed in popularity after successfully joining magnesium and aluminum. Today, it’s an appealing replacement for gas and manual metal arc welding because it uses an inert gas shield instead of slag to protect the weld pool. 

At VeriForm Inc, TIG welding is one of our core processes due to its corrosion and crack-resistant welds and compatibility with a wide range of metals and fillers. In this article, we look at how TIG welding works and analyze both its advantages and disadvantages in terms of application, operator skill, and efficiency.

TIG Welding: the Process

During TIG welding, a pointed tungsten electrode and the workpiece are joined by an arc in an inert environment of helium or argon. Small intense arcs created by these pointed electrodes are ideal for precision and high-quality welding. Since the electrode is not consumed, welders don’t need to balance the heat input from the arc. Filler metal must be added separately to the weld pool when it is needed.

Advantages of TIG Welding

Make Clean, High-Quality Welds

When appearances matter, you can create clean welds with TIG due to its superior arc and weld puddle control. TIG welding allows you to control the weld puddle’s temperature with a foot pedal, similar to driving a car, giving you precise control over the weld bead. Therefore, TIG welding is ideal for cosmetic welds such as automotive and metal sculpting.

In addition:

  • With TIG welding, no smoke or fumes are produced, unless the metal being welded contains oil, grease, paint, lead, or zinc. Welding should begin with a clean base metal.
  • The welding puddle only contains the necessary amount of filler metal, so there is no spatter or sparks when you work with clean metal.
  • No flux needs to be applied or used because the Argon gas protects the weld puddle from contamination. There is also no slag to obstruct your view of the weld puddle and the finished weld won’t have any slag that needs to be removed between passes.

Only One Shielding Gas is Needed 

The versatility of Argon allows you to TIG weld all metals and thicknesses, so you only need one gas in your shop. This simplifies the welding process since you don’t have to work with a variety of gas types.

More Versatile Welding

You can make TIG welds in any position – flat, horizontal, vertical or overhead. This versatility makes it an ideal option for shops that produce items like roll cages or need to carry out welding work in tight or confined locations.

Furthermore, TIG welding can weld a greater variety of metals and alloys than any other method available. You can use this process to weld steel, nickel alloys, bronze, copper, magnesium and even gold. In the case of thin sheet metal, there is no better arc welding process: TIG prevents warping, discolouration, and burn-through by using multiple arc and heat control methods.

Greater Operational Control

TIG welding uses tungsten electrodes to create the electrical arc, which improves control. Unlike stick or MIG welding, where a consumable electrode melts into the weld area, tungsten electrodes heat and melt the filler material that is fed into the weld area by the operator. The level of control can make a difference in the quality of the results.

In addition:

  • Foot pedals control amperage to the electrode, which is not the case with other welding methods, such as MIG (gas metal arc welding), in which the arc voltage is set at a preset value. A TIG welding setup has variable amperage, which is one of the main differences between it and processes like MIG welding.
  • TIG welding’s filler material application helps to achieve control. As we mentioned before, TIG welding electrodes are non-consumable, so the operator can better control the amount of filler rod used by separating the filler metal application from the heating step. MIG welding, on the other hand, uses the gun as both an electrode and a filler material.

Disadvantages of TIG Welding

TIG Welding Can Be Difficult

Although TIG welding equipment and materials are relatively affordable, skilled and experienced technicians are needed to perform the process, which can result in higher labour costs. (Even the most experienced welders gradually switch over to TIG welding.) 

Welders without experience have a hard time handling heat with the pedal, as an accidental jerk will create small welding craters on the metal surface. Improperly performed inclusions, contaminations, and unbalanced heating can result in warped or defective products, as well as wasted materials.

TIG Takes Longer

TIG welding takes a lot of time. The kind of precision it’s known for is extremely time-consuming compared to other technologies like stick welding. The machines themselves also need to be thoroughly cleaned after each use: since any contamination will corrode the surface being welded, there is no room for error.

Overheating is a Risk

As the temperature is controlled by a pedal, distractions or operational errors can cause overheating. Upon overheating, the metal surface will discolour instantly, making the joint brittle and prone to breaking. You won’t be able to reduce the amperage smoothly if you haven’t developed the pulsing ability. Overheating will result in every time.
