Structure, main size and basic parameters of two pieces glass-lined steel vessels with agitator
1 Scope
This standard specifies the structure, classification, main size, parameters and marks of two pieces glass-lined steel vessels with agitator.
This standard is applicable to two pieces glass-lined steel vessels with agitator with design pressure less than or equal to 1.0 MPa in inner vessel, nominal volume of 50 L to 5,000 L, design pressure less than or equal to 0.6 MPa in jacket, and design temperature not lower than –20°C and not higher than 200°C in inner vessel and jacket.
