Construction Seamless Steel Pipe Astm A312 Tp316l Gas Oil Hot Rolled
Seamless steel pipe is a steel pipe made of whole round steel pierced without welded seams on the surface, called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, top pipe, etc.
