ASTM A500 square tube

thick-walled circular pipe diameter changing equipment; can produce circular pipes with a maximum thickness of 24mm

2,production line of high-accuracy cold pipe and opening-type steel section; the pipe specification is 20*20-150*150,with a wall thickness of 0.8-8mm and bending/distorting degree of 0.2/1000-0.1/1000. it could produce special-shaped steel sections(triangular,octagonal,texagonal ellipse,etc.). and can also produce all kind of opening-type steel sections.3, thick-walled circular pipe diameter changing equipment; can produce circular pipes with a maximum thickness of 24mm (specifications;190*20.216*20,267*20),user-defined.4, production of hot-rolled square pipe(50*50-350*350,2-18mm); covers hot-rolled special-shaped steel sections up to European standard of American standard. It can also produce right-angle square pipe with a high mechanical performance.
