High-pressure steel pipe is used in manufacturing high quality carbon steel of high pressure vessels and piping,alloy structural steel and stainless steel seamless pipe.Manufacturing methods are divided into hot-rolled (extrusion, expansion) and cold drawn (rolled). Among them, touter diameter of hot-rolled (extrusion, expansion) steel tubes range is 2.0 ~ 70mm;outer diameter of cold drawn (rolled) steel pipe range is 10 to 108mm;wall thickness range of 2.0 ~ 13mm.
Application of high-pressure steel pipe: high-pressure steel pipes have a good room and high temperature mechanical properties, strict quality control,which is suitable for a variety of high-pressure conditions in the workplace. The high-pressure pipe is mainly used for boilers, high pressure fuel pipe, fertilizer, equipment and piping and other fields.
