Basic Information
Scope
This regulation applies to simple pressure vessels that meet the following conditions simultaneously: (I) The vessel consists of a cylindrical body and a flat head, a convex head (excluding spherical heads), or two convex heads; (II) The materials of the main pressure-bearing components such as the cylindrical body, heads, and manifolds are carbon steel and austenitic stainless steel; (III) The design pressure is less than or equal to 1.6 MPa; (IV) The volume is less than or equal to 1000 L; (V) The product of the working pressure and the volume is greater than or equal to 2.5 MPa·L and less than or equal to 1000 MPa·L; (VI) The medium is air, nitrogen, and water vapor evaporated from medical distilled water; (VII) The design temperature is greater than or equal to -20℃, and the maximum working temperature is less than or equal to 150℃; (VIII) Welded vessels that are not directly exposed to flames.
