This standard applies to stainless steel pressure vessel includes a fixed pressure vessel, stainless steel bottles, , stainless steel removable stainless steel pressure vessel and pressure piping such as stainless steel heat exchanger. Stainless steel pressure vessel and other mechanical equipment can also refer to adopt. The criteria used in the manufacture of stainless steel pressure vessel means a chromium content of not less than 16% of the acid-resistant steel, including austenitic stainless steel, ferritic stainless steel and austenitic-ferritic duplex stainless steel, but does not include martensitic precipitation hardening stainless steel and stainless steel. Both pressure processing stainless steel and welded joints, including stainless steel and surfacing. This standard stipulates that the intergranular corrosion susceptibility own stainless steel pressure vessel inspection requirements. Also provides for the manufacture of stainless steel raw materials used in pressure vessels, corresponding inspection requirements of welding materials and outsourced components. This standard relates to intergranular corrosion means sensitized state intergranular corrosion, excluding non- sensitized state intergranular corrosion. | GB/T 21433-2008: Detecting susceptibility to intergranular corrosion in stainless steel pressure vessels

1.1 standard applies stainless steel pressure vessel comprising a fixed stainless steel pressure vessels, stainless steel heat exchanger, stainless steel cylinders, stainless steel
Mobile stainless steel pressure vessels and pressure pipelines. Stainless steel pressure vessel and other mechanical equipment may also refer to the use of (hereinafter
"Pressure vessel" is sometimes referred to as "container").
1.2 This standard applies manufacture stainless steel pressure vessel means a chromium content of not less than 16% of the acid-resistant steels, including austenitic stainless steel, ferritic
Stainless steel and austenitic - ferritic stainless steel, but does not include martensitic stainless steel and precipitation hardening stainless steel. Both pressure processing is not
Stainless steel and welded joints, as well as stainless steel and the cladding layer.
