Square Tube Is How The Production

- Nov 29, 2017 -

A seamless square tube manufacturing process can be divided into: hot (extrusion), cold-rolled (pull), thermal expansion of the basic types of pipe. Pipe according to the manufacturing process can be divided into: straight seam welded steel pipe, submerged arc welded pipe, steel plate butt welded pipe, pipe thermal expansion pipe.

2, seamless square tube, square tube is four corners, cold drawn seamless steel pipe extrusion molding of square steel pipe, seamless square tube and welded square tube is essentially different. Steel has a hollow section, a large number of pipes used to transport fluid.

3, welded steel pipe, also known as welded pipe, is made of steel or welded steel pipe by curling after forming, generally length 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less equipment investment, but the general strength is lower than the seamless steel pipe.
