In case of any doubt about the English translation, the Chinese original shall be considered authoritative. China Petroleum and Chemical Industry Association, mobilized by China Petroleum & Chemical Engineering Survey and Design Association, was in charge of revision of this code according to the requirements of the Ministry of Industry and Information Technology (GONGXINTINGKE No.104 [2009]) and China Petroleum and Chemical Industry Association (ZHONGSHIHUALIANZHIFA No.136 [2009]) This code replaces HGJ 206-1992 Code for construction and acceptance of chemical machine installation engineering (Medium/small piston-type compressor) from the date of implementation. This code was revised by the compilation team based on extensive investigation and research, practical experience, reference from advanced relevant international standards and extensive solicitation of opinions. The main technical content of this code includes: general provisions, terms, construction preparations, site assembly compressor installation, integral compressor installation, auxiliary equipment and piping installation, test run of set, handover of technical documents, etc. Compared with HGJ 206-1992, the main changes of this code are as follows: 1. Clause 2 "Terms", Clause 6 "Auxiliary equipment and piping installation", Annex A "Aligning for middle body" and other contents have been added; 2. Annex A "Installation of compressor sets without shim iron", Annex B "Tightening torque of anchor bolts and reference value of axial tension" and Annex E "Recommended recipe of pickling passivation solution for carbon steel and low alloy steel pipe" of the original standard have been deleted; 3. The names and contents of other clauses are also adjusted, modified or supplemented. This code was proposed by and is under the jurisdiction of the China Petroleum and Chemical Industry Association. The technical content of this code is interpreted by China National Chemical Engineering No.14 Construction Co., Ltd. If you have comments and suggestions on this code for future reference during its implementation, please contact China Chemical Engineering No. 14 Construction Co., Ltd. (Contact address: No. 148, Xinhua Road, Dachang, Luhe District, Nanjing, Jiangsu, Zip code: 210044, Tel: 025—58380722 ). 1 General provisions 1.0.1 This code is formulated in order to improve the installation of medium and miniature sized piston compressor sets, strengthen the quality control in the compressor installation process, and ensure the quality of installation. 1.0.2 This code applies to the construction and acceptance of on-site assembly or integrated installation of medium and miniature sized piston compressor sets in the chemical and petrochemical industries. 1.0.3 The general technical requirements for installation engineering construction and acceptance of medium and miniature sized piston compressor sets shall comply with the relevant provisions of the current industry standard HG 20203 Code for construction and acceptance of chemical machine installation engineering (General purpose requirement). 1.0.4 Where this code is inconsistent with the requirements of the accompanied technical documents of the compressor sets, the latter shall prevail. 1.0.5 The construction and acceptance of the installation of medium and miniature sized piston compressor sets shall not only comply with this code, but also comply with the relevant current national standards. 2 Terms 2.0.1 piston compressor a machine that works through the piston or plunger making a reciprocating linear motion to periodically change the working volume formed within the cylinder for the purpose of increasing the gas pressure and transporting the gas 2.0.2 throw the sign of the centerlines of the compressor cylinder, the number of throw is the number of the centerlines of the cylinder 2.0.3 stage the sign indicating that the compressed gas has been compressed to the predetermined amount of pressure boost 2.0.4 horizontal compressor a compressor whose cylinder centerlines are all on the same horizontal plane 2.0.5 vertical compressor a compressor whose cylinder centerlines are all on the same vertical plane 2.0.6 oil free compressor a compressor that does not use lubricating oil between the friction surface of the cylinder and the reciprocating parts 2.0.7 test run test operation of the processing equipment, machines or the entire processing system after installation 2.0.8 unload test run test operation of the set under load-free conditions after installation 2.0.9 onload test run test operation of the processing equipment, machines or entire processing systems under loaded conditions 3 Construction preparation 3.1 Technical preparation 3.1.1 The set shall have the following technical documents before installation: 1 End-of-manufacturing certificate. 2 The quality inspection certificate, which shall include the following contents: 1) Product quality certificates for accompanied pipes, valves, pipe fittings and fasteners; 2) Product quality certificate and manufacturing inspection certificate of pressure vessels; 3) Hydraulic test records of cylinder jacket and packing box; 4) Records of pre-assembly and trial operation of the compressor before leaving the factory. 3 The assembly drawing, process flow chart, auxiliary equipment installation drawing, wearing parts processing drawing and the product instruction manual of the set.
