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.

Bending Square Tube

Section bending machine can bend all types of pipe and tubing including aluminum, stainless and carbon steel. It even bend specialty materials such as copper, zirconium and titanium.

Bending rectangular tubing

Rectangular tube bending is the same as rectangular tube bending for the profile bending machine. The difference is that the bending parameter size is determined according to the bending height.

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.
