Best Pipe Bending Methods For Your Project

Each bending method has its place in the pipe bending industry, and choosing between them typically depends on the specific requirements of the project, including the type of material, the wall thickness of the pipe, and the necessity for maintaining internal diameter integrity.

Mandrel Pipe Bending


  • Prevents Deformation: Mandrel bending involves inserting a mandrel—a solid rod or linked ball—inside the pipe during the bending process. This supports the pipe internally, preventing it from collapsing, wrinkling, or deforming, which is crucial for thin-walled pipe.
  • Maintains Cross-sectional Integrity: Maintains the cross-sectional area of the pipe, ensuring that the flow characteristics are maintained, making it ideal for applications requiring a smooth internal surface.


  • Complex Setup: The process requires more complex setup and adjustments, making it slower and generally more expensive than some other bending methods.
  • Limited to Certain Materials: Not all materials are suitable for mandrel bending, as some may be too brittle or hard, limiting its applicability.


Rotary Draw pipe Bending


  • High Precision: Rotary draw bending provides a high degree of control and accuracy, making it suitable for creating precise, repeatable bends, a preferred choice for architectural and automotive applications where exact specifications are critical.
  • Versatility: It can be used on a variety of materials and sizes, often without requiring the inner support that mandrel bending does, allowing for a wider range of applications.


  • Risk of Deformation: Without the internal support provided by a mandrel, rotary draw bending can lead to some degree of deformation, particularly in pipes with thinner walls or larger diameters.
  • Wrinkling and Flattening: There is a higher risk of wrinkling or flattening at the bend, especially if the pipe has a high diameter-to-thickness ratio.

Roll bending is distinct from mandrel and rotary draw bending in terms of its applications and the outcomes it produces, which is why it was not directly compared with the other two methods. Roll bending is primarily used for creating large radius bends or continuous circular shapes, suitable for large structures like tanks, drums, or architectural features. This method differs fundamentally from mandrel and rotary draw bending, which are more focused on achieving precise and tight radius bends with high degrees of accuracy and minimal deformation. Roll bending excels in larger-scale projects with less stringent requirements on cross-sectional deformation.

Roll Bending and it's Difference in Precision Pipe bending

Pipe Sizes A&S Bending is Equipped for

1"-12" Diameter Pipes

Perfect for detailed applications in structural and architectural projects, such as custom railings or unique architectural details. A&S Bending uses precise bending techniques like CNC mandrel bending to ensure accurate and aesthetically pleasing results for these smaller-diameter pipes.

12"-24" Diameter Pipes

Often used in the natural gas and mining industries for pipelines and conveyance systems. Our advanced mandrel bending ensures that these mid-sized pipes maintain their structural integrity and meet strict industry standards, supporting efficient and safe operations.

24"-36" Diameter Pipes

These large-diameter pipes are commonly needed in maritime and industrial applications, including shipbuilding and large-scale manufacturing facilities. Techniques such as roll bending and induction bending are utilized to manage the significant size and weight, ensuring smooth bends that are crucial for both performance and durability.

Schedules of Pipe

A&S Bending accommodates pipes with various schedules, which determine the wall thickness and are crucial for applications requiring specific pressure ratings. We handle pipes from Schedule 10 to Schedule 160, serving industries like natural gas, where higher schedule pipes are essential for ensuring safety and durability under high pressure.

Understanding Pipe Schedules

Definition of Pipe Schedules

Pipe schedules refer to the wall thickness of a pipe, which is directly linked to the diameter of the pipe and its ability to withstand different internal pressures. The schedule number increases with the thickness of the pipe wall. Common schedules include Schedule 40, Schedule 80, and Schedule 160, with each providing different degrees of robustness and capability to handle pressure.

Importance in Pipe Bending

The schedule of a pipe determines the techniques and tools necessary for effective bending. Thicker-walled pipes (higher schedules) require more robust bending methods to prevent cracking or deformation. For example, high-schedule pipes might need heat-assisted bending processes or specialized mandrels to support the interior during bending to maintain integrity and prevent collapse.

Application Considerations

Different industries require pipes of specific schedules based on the environmental and operational pressures the pipes will face. For instance, pipes used in the natural gas industry often need to be of higher schedules to safely handle high pressure. Understanding the correct schedule for an application ensures that the pipe performs safely and efficiently in its designated role.
