Seamless Circular Steel Tube is a steel pipe perforated from a whole round steel, and there is no weld on the surface, which is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes.
Surface finished: Black primer painted, red color primer painted, red primer painted, epoxy coated inner, hot-dipped galvanized, anti-rust oiled, 3PE etc.
Technic method:Hot-rolled, cold rolled, hot expand
