Alloy pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature, low temperature and corrosion resistance performance is unmatched by ordinary seamless steel pipe, so alloy pipe is widely used in petroleum, aerospace, chemical, power, boiler, military and other industries.
