Alloy pipe is a kind of seamless steel pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe , so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.
