Special Shaped Pipe
Special shaped pipe is a kind of seamless steel pipe made by cold drawing. The special-shaped seamless steel pipe is the general term of seamless steel pipe with other cross-section shapes except round pipe. -
Galvanezed Seamless Steel Pipe
Galvanized seamless steel pipe is hot-dip galvanized, so the amount of zinc plating is very high, the average thickness of zinc coating is more than 65 microns, and its corrosion resistance is much different than that of hot-dip galvanized pipe. The regular galvanized pipe manufacturer can use cold galvanized pipe as water and gas pipe. The zinc coating of cold galvanized steel pipe is electroplated layer, and the zinc layer is separated from the steel pipe substrate. The zinc layer is t... -
Heavy Wall Steel Pipe
The production and manufacturing process of heavy wall seamless steel pipe can be divided into cold drawing, cold rolling, hot rolling and hot expansion. The materials of steel pipe are 10, 20, 35 and 45, which are called ordinary steel pipe. According to the application, it can be divided into structural seamless steel pipe, seamless steel pipe for transportation, seamless steel pipe for boiler, high-pressure seamless steel pipe for boiler, high-pressure seamless steel pipe for chemical fert... -
Precision Seamless Steel Pipe
Precision seamless steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling treatment. Because there is no oxide layer on the inner and outer wall of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending -
Boiler Seamless Steel Tube
Mainly used to manufacture high-quality carbon structural steel and alloy structural steel seamless steel pipes for steam boiler pipes with high pressure and above. -
