ASTM A213 Heat Exchanger Tubes

‌ASTM A213 standard applies to seamless ferritic and austenitic alloy steel pipes for boilers, superheaters and heat exchangers. ‌ The standard covers a variety of steel pipes, including but not limited to TP304, TP304H, TP316, TP316H, TP321, TP321H, TP347, TP347H, etc.‌12.
According to the ASTM A213 standard, these steel pipes have a wide range of specifications, with outer diameters ranging from 20mm to 760mm and wall thicknesses ranging from 2.0mm to 120mm. The production methods mainly include cold rolling and cold drawing, and the delivery state is usually heat treated and pickled.‌
ASTM A213 stainless steel heat exchanger tubes are usually used in high temperature environments, such as superheaters and reheaters. With excellent high temperature resistance and good corrosion resistance, they can withstand high pressure and high temperature working environments.
