GB/T 17393-2008
ActiveSpecification for thermal insulation for use in contact with austenitic stainless steel
覆盖奥氏体不锈钢用绝热材料规范
Application Summary AI generated
This standard specifies the technical requirements for thermal insulation materials that are in direct contact with austenitic stainless steel, primarily to prevent stress corrosion cracking caused by chloride ions. It is applied in the construction and industrial sectors, particularly for insulating pipelines, vessels, and equipment made of austenitic stainless steel in environments such as petrochemical plants, power stations, and refrigeration systems. The standard ensures that insulation materials meet strict limits on leachable chloride, fluoride, and silicate ions to protect the integrity of the stainless steel surface.
