This article will give an overview of steel pipes, the common sizes used as well as how to cut and bend steel.

Common Steel Pipe Sizes

Steel pipe is very versatile and can be created to any size or dimension. Steel pipe is generally measured in three ways: thickness, the nominal bore (NB) (which measures the hollow section) and the outside diameter. Below is a table of the most common steel pipe sizes available.

Outside Diameter (OD) Nominal Bore (NB) Outside Diameter (OD)
27mm 20 2.0 (extra light) 2.3 (light) 2.6 (medium) 3.2 (heavy)
34mm 25 2.0 (extra light) 2.3 (light) 2.6 (medium) 3.2 (heavy)
42mm 32 2.0 (extra light) 2.3 (light) 2.6 (medium) 3.2 (heavy)
48mm 40 2.0 (extra light) 2.3 (light) 2.6 (medium) 3.2 (heavy)
60mm 50 2.0 (extra light) 2.3 (light) 2.6 (medium) 3.2 (heavy)
76mm 65 2.0 (extra light) 2.3 (light) 2.6 (medium) 3.2 (heavy)

How to Cut Steel Pipe

Steel pipe is naturally strong and resistant to damage, so to cut it to size, a specialised tube or pipe cutter is used.


Some cutters will need to be manually adjusted to change the aperture, while others automatically adjust. There are other methods, such as using angle grinders or saws, but they will offer a poorer result than a pipe cutter.

How to Bend Steel Pipe

Due to the natural properties of steel pipe, bending it to shape can be a labour-intensive process.


One of the easiest ways to bend steel pipe is using a pipe bender. This custom tool applies hydraulic force to the pipe to manipulate its shape and create a bend in the steel.


There are other, less effective ways to bend steel, such as with a blowtorch or tube roller. However, the risk of injury and poorly bent pipes is much higher when compared to a pipe bender.
