| Summary | This standard specifies the steel chemical vessel steel and weld material selection, technical requirements, limitations and scope of new materials and production of steel by using foreign standards, steel alternative requirements. This standard applies to the design pressure of not more than 35. 0MPa, the design temperature is higher than -20��C carbon steel, low alloy high strength steel, pearlitic heat resistant steel, stainless steel and stainless steel welded composite material used chemical containers. Variety of materials including rolled products, forgings, castings, and welding materials. Pressure vessel components and accessories welding material selection, technical requirements, scope of use should be consistent with the requirements of this standard. Design of materials with higher or special requirements, drawings or shall indicate on the appropriate file. |
