Product description

ASTM A213 T91 tube is a type of seamless ferritic alloy steel tube used in high-temperature applications. It has a composition of chromium, molybdenum, and vanadium, which provides high strength, corrosion resistance, and excellent creep and rupture strength at elevated temperatures. ASTM A213 T91 tube is commonly used in power generation plants, petrochemical refineries, and other industries where high-temperature and high-pressure conditions are present. It is available in various sizes and thicknesses to meet specific requirements.

Pipe Process of ASME SA213 T91 Steel tube / ASTM A213 T91 Alloy Steel Seamless tubes:
