Product details

ASTM A213 T22 is a standard specification for seamless steel tube ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. The T22 designation refers to the grade of steel used in the tube, which is a low alloy steel with 2.25% chromium and 1% molybdenum. This kind of steel pipe is commonly used in high-temperature applications, such as in power plants and petrochemical plants.

Pipe Process of ASTM A213 T22 Alloy Steel Pipe:

Round Billet → Material Inspection → Grinding → Cut to Length → Heating → Piercing → Bite mandrel → Hot Rolled → Get Rid of Mandrel → Heat Treatmen t → Size Reducing → Cooling → Straightening → Semi Manufactured Product → Corp End Cutting off → UT/ET TEST or Hydrostatic Test → Marking → Packing → Warehousing
