Product Description
High Quality Q235 Q345 Hot Rolled Carbon Seamless Structure Pipe
Seamless Structure Pipe(GB/T8162-2008) is a seamless tube for general structure and mechanical structure. It is a kind of seamless steel pipe which is divided into different kinds because of its different uses.GB/T8162-2008 (seamless pipe for structure) is mainly used in general structure and mechanical structure. Its representative materials (grades): carbon steel 20, 45 steel, Q235, alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.Because of its different manufacturing process, it can be divided into hot-rolled (extruded) seamless steel pipe and cold-drawn (rolled) seamless steel pipe. Cold-drawn (rolled) pipes are divided into circular pipes and special-shaped pipes.
