Because this JIS G3456 STPT480 steel pipe is a seamless structure, the fluid resistance is small, the flow performance is good, and the pressure loss of the fluid in the pipeline can be effectively reduced. Therefore, JIS G3456 STPT
480 high-pressure carbon steel pipe is also widely used in industrial fields such as petroleum, chemical industry, and electric power.
