According to the arrangement of Chemical Construction Standard (1996) No. 90, the original chemical design standard "Equipment Layout Model Design Specification" (CD43A2-87) was revised by the National Chemical Engineering Model Design Technology Center to this regulation, which was reviewed and finalized by the Technical Committee of the station. The content of this regulation includes: general principles, the function and application scope of equipment layout model design, the work procedure table of equipment layout model design, the design and production of equipment layout model, the results of equipment layout model design and clause explanation, etc.
During the revision, the professional names, professional division of labor and design work procedures in the original regulations were adjusted according to the international general design system and methods. At the same time, based on the summary of the equipment layout model design experience in the chemical, petrochemical, pharmaceutical and other industries, the selection ratio and condition relationship were modified accordingly.
This regulation is managed and interpreted by the National Chemical Model Design Technology Center. The address of the station is No. 20, Lane 767, Wanhangdu Road, Shanghai (Postal Code: 200040); Tel: (021) 62678992.
This regulation is edited by the National Chemical Model Design Technology Center. Main drafters: Gu Guoliang, Jiang Lianbao, Zhang De Equipment layout model design is an auxiliary design method for professional designers of process equipment layout in the engineering design stage. In order to improve the application level of equipment layout model design, this regulation is specially formulated.
This regulation is applicable to the equipment layout model design of devices or workshops in the chemical, petrochemical, pharmaceutical and other industries.

20648-1998
Article·Explanation
1.0.1~1.0.2 These regulations apply to the equipment layout model design of devices or workshops in the chemical, petrochemical, pharmaceutical and other industries.
2 Functions and application scope of equipment layout model design 2.1 Compared with the original regulations (CD43A2-87, the same below), this regulation has made corresponding enrichments in terms of the functions of equipment layout model design based on the actual use effect to give full play to its due role.
Equipment layout model design work procedure table
Compared with the original regulations, this regulation simplifies the equipment layout model design work procedure and readjusts the professional names, professional division of labor, design work procedures, etc. in the original regulations according to the direction of the current design system reform. 4 Equipment layout model design and production
4.1.14.1.2 According to the different characteristics of the chemical, petrochemical, pharmaceutical and other industries, this regulation has different requirements for the proportion of model design selected for large, medium and small-scale devices. This revision has made corresponding adjustments to the recommended model selection proportions in the original regulations. 4.3 This regulation changes the original "basis for equipment layout model design" to "technical conditions for equipment layout model production", and clarifies the requirement that the process equipment layout profession should be the main body and the relevant professions should be coordinated to provide the model design profession with the technical conditions for production. 22
