Induction Bending

Precise tube and pipe bends for optimum strength and consistency

Induction bending uses heat and controlled force to shape pipe while preserving the cross section. This method allows for precise bending of large-diameter pipe, including square and rectangular tubes. Induction bending reduces material deformation, maintains cross-sectional integrity, and supports tight radius bends.

We have been innovating the pipe bending industry since 1958. As a nationally recognized leader, we bring decades of experience to each project, delivering exact bends across a wide range of materials, sizes, and applications. Our processes are designed to meet demanding industry specifications and serve critical infrastructure across the country.

Our induction bending capabilities include:

  • Heat induction pipe bends from 3.5 inches to 36 inches OD
  • Compliant with ASME B16.49, TPA-IBS-98, and most internal company specifications
  • Used in power plants, petroleum pipelines, and road signage
  • Consistent, repeatable results across a wide range of materials

Frequently asked questions

Induction pipe bending utilizes localized heating through an induction coil to soften a specific section of the pipe, allowing it to be bent precisely without compromising structural integrity. Unlike traditional cold bending methods, which can cause wall thinning and ovality, induction bending offers high precision, uniform wall thickness, and minimal distortion, making it ideal for tight radius bends and complex shapes.

Tulsa Tube Bending can bend most grades of carbon steel, stainless steel/duplex, chrome, nickel alloys, and aluminum pipe and tubing. As a rule, the ductility of the material and the bend radius specified are the two primary factors that determine if a bend can be made. The selection of material depends on factors such as pressure, temperature, and environmental conditions, ensuring the bent pipes meet specific application requirements.

Induction bending can enhance the strength and durability of pipes by increasing their yield and tensile strengths due to rapid cooling after heating. This process typically results in a harder microstructure, especially in the austenite phase of steel. However, it may reduce ductility, which can be mitigated through heat treatment. Compared to cold bending, induction bending better preserves or even improves mechanical properties like toughness, minimizing wall thinning and distortions.

Order higher quantities when possible.
Common sizes, wall thicknesses, and grades are more cost-efficient. Many sizes listed in pipe charts are specialty items and cost more due to limited production. Our experienced sales team can help you select widely available options that meet your specs.

Use standard bend radii.
Modern techniques can achieve nearly any radius, but some cost more. Many projects have flexibility in radius selection. Choosing a common radius and adjusting tangent lengths can lower your total cost. Submit a quote and we’ll help you explore the most efficient radius options.

Consider welded pipe or tube.
Today’s welded material often meets or exceeds quality standards once reserved for seamless. For many applications, switching to welded can reduce costs by 25% to 40%.

Simplify end preparations.
Unless your project requires square or beveled ends, opt for plain or rough cut. This slight change can lead to significant savings. Refer to our end prep guide to choose what fits your needs.

Avoid rush orders when possible.
Standard lead times (typically 3 to 5 days for small jobs) allow us to group similar orders and reduce set-up costs. Planning ahead helps keep your project on time and on budget.

At Tulsa Tube Bending we try to make it as easy as possible to specify your bends, by giving you the option that is easiest for you.

  • Input your information into our online quote and we’ll email with price and lead time.
  • If you have a sketch, drawing or print, please attach it to the quote form. We can currently accept .bmp, .tif, .gif, .jpg, .pdf, .dwg, or .dwf files. You are also welcome to fax it to us at the number listed at the bottom of the web page.

We will need to know the following for every bend:

  • Quantity of bends
  • Outside diameter of pipe/tube or nominal pipe size
  • Wall thickness or pipe schedule
  • Material grade
  • Degree of bend or arc length of bend
  • Radius of bend
  • Required tangent lengths
  • End preparation (plain, square cut, beveled, etc.)

Built for industry standards

Every induction bend we produce is aligned with ASME B16.49, TPA-IBS-98, or your internal project specifications. Our quality-first approach ensures compliance across refining, chemical, power, and infrastructure applications.

Precision across every radius

From tight turns to broad sweeps, we deliver reliable, repeatable bends with minimal distortion. We maintain cross-sectional integrity even in large-diameter pipe, square tubing, and high-performance alloys.

Decades of trusted performance

Since 1958, we have been the go-to resource for complex pipe bending. Our experienced technical sales force and modern equipment help you move from quote to completion with unmatched efficiency.

I have closer pipe bending sources, but I’ve found that Tulsa Tube Bending offers an overall product and service value that overcomes the distance between us. Quick deliveries, excellent quality, good service and FOB delivered prices make it easy for me to do business with Tulsa Tube Bending.

David, Seattle, WA
I like the friendly customer service and the emailed quotes. My sales representative is very knowledgeable and offers me cost saving alternatives. I especially like the firm quoted freight cost that is added to my order.
Mark, Kansas City, MO
I’ve dealt with Tulsa Tube Bending for many years. Pipe bends that in the past took two to four weeks to deliver can now be turned in three to five working days. These quick project turnarounds are just what my customers are looking for.
