About Cloth Chemical Machinery Notice on the two industry standards of centrifugal compressors and small and medium-sized chamber type compressors
All provinces, autonomous regions, and municipalities directly under the Central Government Chemical Industry Department (hereinafter referred to as the "Ministry of Industry Standards"), we have commissioned China Net Chemical Engineering No. 1. The second construction company of China Net Chemical Engineering Co., Ltd. to formulate the second construction and acceptance specifications for chemical machinery installation projects for low-cost and medium-sized scientific and technological compressors; the thirteenth construction company of China National Chemical Engineering Co., Ltd. to formulate the construction and acceptance specifications for chemical machinery installation projects for centrifugal compressors. After consultation with relevant units, they are now approved as the chemical industry construction standards. The missing numbers are HGJ20E-92 and I1GT20-92 respectively. Since the implementation of the two standards in October 2012, the original standards for small and medium-sized chamber type gas compressors and technical specifications for improvement (trial) (Chemical Class 10377) and technical specifications for the construction and acceptance of medium and low-cost and high-pressure centrifugal compressors (Trial 18 (Chemical Class 102-77) are currently in force.

According to the arrangement of the Ministry of Chemical Industry (90) Chemical Standard No. 21, the Ministry entrusted China Chemical Engineering Thirteenth Class Design Company to interpret the medium pressure centrifugal compressor lung construction and acceptance technical specifications (trial) training chemical 1 ton 7) plate. During the revision of this specification, the implementation of the original specification was analyzed, the construction experience of special projects such as refractory, ethylene, pure spherical, and joint-stock projects was summarized, and the latest versions of technical standards at home and abroad were consulted. The technical indicators of this specification are determined based on the latest domestic technology of centrifugal machines, industrial steam turbines, and the technical standards of products in the 1980s, which are in line with the current level of mechanical innovation in my country. This specification is widely coordinated with the standards of relevant majors, and after review, it is determined that the specification is of customer-oriented nature: the material variation of the specification within the warranty period is revised, which will improve the construction progress, reduce the cost of construction, and ensure the safety of the workers. It will play a positive role in meeting social pressure. With the development of construction industry and the improvement of cutting machine manufacturing level, new materials and new machines will emerge continuously. We hope that all units can summarize their experience and provide improvement suggestions in the process of inspection and standardization, so as to provide more comprehensive information.
