ASTM1020/1035/1045/4140 ST52 27SiMn 41Cr4 Heavy Wallthickness Seamless Steel Pipe
Short Description:
Heavy wall seamless steel pipe is a type of pipe with higher wall thicknesses than average.
Heavy wall seamless steel pipe is a type of pipe with higher wall thicknesses than average. The manufacturing process of heavy wall steel seamless pipe can be divided into four basic methods: cold drawn, cold rolled, hot rolled, and hot expansion. According to the purpose, it can be divided into seamless steel pipe for structure; seamless steel pipe for liquid transport; high-pressure seamless steel pipe for boiler; high pressure seamless steel pipe for fertilizer equipment; seamless steel pipe for geological drilling; seamless steel pipe for oil drilling; seamless steel pipe for oil cracking; seamless steel pipe for shipbuilding; various alloy pipes. Seamless steel pipes are indicated by outer diameter and wall thickness.
