Notice on the promulgation of the "Specifications for the Commissioning of Large and Medium-sized Plants in the Chemical Industry"
To the chemical industry departments (bureaus) of all provinces, autonomous regions, municipalities directly under the Central Government and cities with independent planning status, Jilin Chemical Industry, Nanning Chemical Industry, Dahua Chemical Industry, Taihua Chemical Industry, and all chemical construction, design and construction units:
On May 3, 1988, our Ministry issued the "Specifications for the Production Preparation and Commissioning of Large-sized Plants in the Chemical Industry" in Document No. (88) Huajizi No. 381. In accordance with the requirements of the State Planning Commission on the "Plan for the Formulation and Revision of Engineering Construction Standards and Specifications", we commissioned China National Chemical Engineering Corporation to compile the "Specifications for the Commissioning of Large and Medium-sized Plants in the Chemical Industry" on the basis of the "Specifications". It is now promulgated as the Chemical Industry Standard of the People's Republic of China, with the serial number HGJ231-91, and will come into effect on October 1, 1991. The commissioning of chemical equipment is the last important stage of chemical engineering construction. Doing a good job in the commissioning is very important for giving full play to the economic benefits of the equipment. Therefore, the leaders of the chemical industry departments (bureaus) and chemical construction units must attach importance to the work of the commissioning stage and personally grasp it and grasp it to the end. This "Specification" is compiled on the basis of summarizing the commissioning experience of domestic and selected chemical equipment, absorbing the conventional practices and commissioning experience of foreign technologically advanced countries. It is more complete and accurate in content than the original "Regulations". In order to enable the new chemical equipment to start smoothly and operate stably and continuously, all chemical industry departments (bureaus) and units are requested to implement it conscientiously. This specification is managed and interpreted by the Infrastructure Department of the Ministry of Chemical Industry. It is hoped that all units will report the problems and experiences in the implementation to the Standard and Quota Department of the Infrastructure Department of the Ministry at any time. This specification is published by the Engineering Construction Standard Editing Center of the Ministry of Chemical Industry (Address: Building 3, Ministry of Chemical Industry Compound, Hepingli North Street, Beijing, Postal Code: 100013).
