面议Alloy steel pipe is a kind of seamless steel pipe, which is made by hot rolling (extrusion, expansion) or cold rolling (drawing). Its performance is much higher than the general seamless steel pipe, because this steel pipe inside containing Cr. Alloy steel pipe is mainly used in high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. The advantages of alloy steel pipes can be 99% recycled, which is environmental protection and energy saving。
