9m 24m Round Construction Seamless Carbon Steel Tube 1.1 / 2" 1.1 / 4" ASTM A192 A179 A192
SA106B SA106C 20G Q345B 27SIMN
Due to their different manufacturing processes, seamless steel pipes are divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes. Cold drawn (rolled) tubes are divided into two types: round tubes and special-shaped tubes.
