According to the arrangement of the Infrastructure Department of the Ministry of Chemical Industry, the Equipment Design Technology Center Station of the Ministry of Electrochemical Industry organized the preparation of design standards and technical regulations for chemical equipment design as a ministerial directive technical document to guide equipment design and manufacturing. Brick Lining Chemical Equipment stipulates the design calculation and technical conditions of brick lining. This standard is revised on the basis of the chemical design standard CD130A11-85 Brick Lining Equipment Design Technical Regulations ≥ and CD130A12-85≤ Brick Lining Equipment Technical Conditions issued by the former Infrastructure Bureau of the Ministry of Chemical Industry. This standard was edited by Xu Jiaxiang of Jilin Chemical Industry Design Institute, checked by Wang Yaodong, reviewed by Wu Fusheng, and partially participated by Wang Jixue.
During the preparation process, extensive investigation and research were conducted, and the design experience of various chemical design units over the years was summarized. After soliciting opinions, review by special personnel and review by the technical committee, the final draft was submitted to the Ministry for approval by the Equipment Design Technology Center of the Ministry of Chemical Industry.
During the implementation of this standard, if any modification or supplement is found, please provide the opinions and relevant information to the Equipment Design Technology Center of the Ministry of Chemical Industry for reference in future revisions.
