Structure, main size and basic parameters of one piece glass-lined steel vessels with agitator 1 Scope This standard specifies the definition, structure, main size, basic parameters and marks of one piece glass-lined vessels with agitator (hereinafter referred as "the vessel"). This standard is applicable to one piece glass-lined vessels with agitators with the design pressure less than or equal to 1.0 MPa, the nominal volume of 1000 L ~ 40000 L, the design pressure less than or equal to 0.6 MPa in U-shaped jacket, and the design temperature higher than -20 °C ~ 200 °C in inner container and jacket. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendment) applies.

The upper heads of the vessels are provided with equipment flanges, and those with the nominal diameter of their equipment flanges of less than half of the nominal diameter of the vessels fall into F-structure, while those without equipment flanges on their upper heads belong to Q-structure.
