ASTMA213/A213M alloy steel pipe "Specification for ferritic and austenitic alloy steel seamless steel pipes for boilers, superheaters and heat exchangers"
SA213 T2 seamless steel tubes are mainly used for superheater and reheater system with working temperature lower than 540 ℃, and also for water wall tube in supercritical boiler.
SA213 T92 steel tubes can partially replace TP304H and TP347H austenitic stainless steel pipes to manufacture sub-critical, super-critical, or even super-supercritical power plant boilers with metal wall temperatures not exceeding 650℃.
Product grades: T2, T5, T5b, T5C, T9, T11, TI2, T21, T22, T23, T91 (Type1. Type2), T92, etc.
Product specifications:
Outer diameter 21.3mm~762mm
Wall thickness 2.0mm~130mm
Production method: hot rolling, cold drawing, hot expansion
Delivery status: Heat treatment and products should be confirmed to comply with the requirements of TSGD7002-2006 "Type Test Rules for Pressure Pipe Components".
