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



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.
