The seamless black steel pipe is a circular pipe with a hollow section and no seams around the pipe. The main material of seamless steel pipe is carbon steel, alloy steel, stainless steel ingot or solid tube blank. GK black seamless steel pipes is cast from several grades of ductile or malleable iron and produced after material by hot rolling, cold rolling or cold drawing.
