T/SASE 004-2022 The production process specification for on-line solid solution heat treatment of austenitic stainless steel welded pipes
Basic Information
Scope
Main technical content: The main content mainly focuses on the heating, insulation, cooling, and safety requirements of online solid solution treatment during the TIG welding production process of austenitic stainless steel welded pipes: (1) Online solid solution treatment heating temperature and heating method: These mainly specify the requirements for the heating method and temperature during the online solid solution treatment process of austenitic stainless steel welded pipes. (2) Online solid solution treatment insulation: These mainly set and require the insulation temperature, insulation method, and insulation time during the online solid solution treatment process of austenitic stainless steel welded pipes. (3) Online solid solution treatment cooling: These specify the cooling medium, cooling method, and other cooling process parameters and indicators for austenitic stainless steel welded pipes during online solid solution treatment. (4) Online solid solution treatment pipe performance testing: After completing the solid solution treatment test, mechanical property tests must be conducted on the solid solution-treated stainless steel pipe components to evaluate whether the solid solution treatment process can achieve the purpose of performance regulation. The main mechanical property testing methods include hardness testing, pipe flaring test, flattening test, and expansion test. (5) Online solid solution treatment safety requirements: These mainly specify the safety protection requirements for protective gases during the online solid solution treatment process.
