Mainly Standard of Alloy Steel Pipe

Alloy pipe is a kind of seamless steel pipe. Its performance is much higher than that of ordinary seamless steel pipe. Because this steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are other. Sewed steel pipes can not match, so alloy pipes are widely used in petroleum, chemical,electric power, boiler and other industries.
