Pipe and tubing is also known as HSS (hollow structural steel), just like square and rectangular tubing, since it is hollow.

Round tube lends itself well to bending because of the symmetry of the part and because, with the proper tubing, the part can be encapsulated well to avoid ovality or other distortion. Generally speaking, tighter bends are more difficult in round tube bending; similarly, the thinner the wall, the more difficult the bend. However, with the correct tooling, machinery, and procedures, excellent quality can be achieved even with tight-radius, thin-wall round tube bending.

Bending Pipe & Round Tube Circular Hollow
BIT series profile bending machine can bend all types of pipe and tubing including aluminum, stainless and carbon steel. We even bend specialty materials such as copper, zirconium and titanium.
Pipe and tubing are specified in different ways. Pipe is NOT called out by the OD size of the material and is not called out with an easily identifiable thickness.
BIT provides detailed information on nominal pipe size and pipe schedules and sets out a complete table of schedule 40 and schedule 80 thicknesses & weights.
Like square and rectangular tubing, round tubing and pipe can be bent with virtually every bending process BIT series section bending machine have available in our shop. Processes include draw bending, roll bending, increment hot bending, increment cold bending and induction bending. The only exception is the plate roll.
W24s series section bending machine can bend all types of pipe and tubing including aluminum, stainless and carbon steel. We even bend specialty materials such as (zirconium and titanium). Carbon pipe (mill produced) is classified as ASTM A53 (most commonly) resulting in a yield point (psi) of 30,000 minimum for grade A and 35,000 for grade B. Carbon tubing (mill produced) are most commonly classified as ASTM A500B resulting in a yield point (psi) of 46,000 minimum for Grade B.

Tubing and pipe can be used in virtually any application but are most commonly used as railings, recreational products (play grounds, bike racks, goal posts), industrial products (boiler tubes, heat exchangers, piping systems) and curved members of canopies and awnings.
