Heat expand carbon seamless steel pipe is a circular pipe with a hollow section and no seams around the pipe. The main material of such hot rolled seamless steel pipe is carbon steel.
In the market, these materials are often found as GK large diameter seamless steel pipe：10# 20# 35# 45# 16Mn 27SiMn 15CrMo 12Cr1MoV 10CrMo910 T91 P91 J55 K55 Q345 Cr5Mo2）20#、35#、45#、16Mn、27SiMn3）10#、20#、35#、45#、16Mn、27SiMn、12Cr1MoV、10CrMo910、15CrMo, etc.
GK hot finished seamless tubing is cast from several grades of ductile or malleable iron and produced after material by hot rolling.
Heat-expanded seamless steel pipes are also called the heat-expanded pipes. Steel pipes with relatively low density but strong shrinkage can be referred to as heat-expanded pipes for short. A rough tube finishing rolling process in which the diameter of a pipe is enlarged by a diagonal rolling method or a drawing method. 15CrMoG steel pipe is widely used in petroleum, chemical, power, boiler and other industries because its performance is much higher than ordinary seamless steel pipe and contains more Cr, and its high temperature, low temperature resistance, corrosion resistance performance .
