PRODUCT DESCRIPTION

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 100% recycled, which is environmental protection and energy saving。

ASTM A335 Alloy Pipe is often called as chrome moly pipe because of the chemical contain of Molybdenum (Mo) and Chromium (Cr). ASTM A335 Alloy Pipe is the seamless ferritic Pipe for high temperature service. ASTM A335 Alloy Pipe finds high usage in power generation industry and petrochemical industry, because of its resistance to corrosion, tensile strength, strength for high temperature and its cost-effectiveness.
 
Chome moly pipe is popular in ASTM A335 standard material P5, P9, P11, P12, P22, P91 and P92.
