Seamless steel pipe is a kind of hollow cross section, no seams around the circle, square, rectangular steel. Seamless steel ingot is made of perforated or solid through the capillary tube, and then by the hot-rolled, cold-rolled or cold call is made. Specifications of seamless steel pipe with outer diameter * wall thickness revealed that the performance of a few millimeters. Hot-rolled and cold rolled seamless steel pipe points (written) seamless steel categories. Hot-rolled seamless steel tube sub-pop. Hot rolled seamless pipe diameter larger than the popular 32mm, wall thickness 2.5-75mm, cold-rolled seamless steel pipe at the Trail can go to 6mm, wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm thickness can be less than 0.25mm , cold than hot-rolled high dimensional accuracy.
