Alloy seamless steel pipe is a kind of seamless steel pipe, its performance is much higher than that of ordinary seamless steel pipe, because this kind of steel pipe contains more Cr, its resistance to high temperature, low temperature and corrosion is less than that of other seamless steel tubes.  Alloy steel pipes are mainly used in power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters and other high-pressure and high-temperature pipes .biggest advantage can be recovered 100%, in line with environmental protection, energy saving, save resources
