Bending stainless steel tube technology in profile bending

Bending stainless steel pipe/tube is a process that can be used to shape stainless steel pipe into many useful configurations.
The difficulty of bending a section of pipe depends on the thickness of the pipe.
Although thick-walled pipe requires more force to bend, it is less likely to fail during the bending process than thin-walled materials.
Pipes of different sizes need their own set of molds.

What is Pipe Bending and Tube Bending

It’s worth a mention firstly that there are two common terms used in industry, tube bending and pipe bending. Tube is measured by the outside diameter whereas pipe is measured by the inside diameter. Pipe sizing refers to the nominal inside diameter, sometimes called nominal bore, rather than the actual inside diameter.

Nominal Pipe Size & Pipe Schedules

NPS, or nominal pipe size, is the North American set of size standards for pipes that are used for temperatures and pressures of all ranges. The nominal pipe size identifies the size of the diameter of the pipe’s hole with a non-dimensional number. Using the NPS, a pipe is identified by its diameter and then with another non-dimensional number for the pipe’s wall thickness.

Tube & Pipe Bending Common Terminology

Tube is bent around a fixed radius die with a mandrel insert in to prevent it from collapsing during bending. The tube or pipe is clamped against the die and this is then rotated whilst the pressure die moves in a straight linear motion. This is the most common form of bending.
