Definition:
Hollow Section is a hollow strip steel, also known as flat tube, square tube or flat Fang Bian tube (as the name implies).A large number of used for conveying fluid pipe, such as oil, natural gas, water, gas, steam, etc., in addition, in the bending and torsional strength phase at the same time, the weight is lighter, so also widely used in the manufacture of machinery parts and engineering structures.Also commonly used for the production of various kinds of conventional weapons, barrel, shells, etc.

Hollow Section is to use hot rolled or cold rolled steel strip or rolled plate for the parent metal by cold bending forming by high frequency welding again after made of square cross section shape, the size of the steel.Hot rolled, thick-walled square tube in addition to outside in the thickness of the wall thickness, the size and edge Angle straightness achieves even exceed the level of the resistance welding cold forming square tube.

Classification:
According to the type, can be divided in square pipe, retangular pipe and round pipe.
According to the process, can be divided in hot rolled seamless steel square tube, cold drawn seamless tube, extrusion of seamless pipe, welded pipe.
