How to calculate a steel pipe and tube theoretic weight

The weight of a pipe depends on the weight density of the material that composes the pipe as well as the physical volume of the pipe.

Square hollow section, rectangle hollow sectionSquare hollow section, rectangle hollow section

A hollow structural section (HSS) is a type of metal profile with a hollow tubular cross section. In some countries they are referred to instead as a structural hollow section (SHS).
Most HSS are of circular or rectangular section, although other shapes are available, such as elliptical.

Igot production The Manufacturing Process of steel pipe

The overall production method for both processes involves three steps. First, raw steel is converted into a more workable form. Next, the pipe is formed on a continuous or semicontinuous production line. Finally, the pipe is cut and modified to meet the customer’s needs.
