1.0.2 This code is applicable to the installation quality acceptance of hydromatic equipment, oil lubricating equipment, grease lubricating equipment, oil fog lubricating equipment, sliding bearing static-pressure oil supply equipment, technological lubricating equipment and air-driven system equipment among the metallurgical machinery.
1.0.3 The requirements for installation quality as given in the engineering technical document adopted during installation of hydromatic, lubricating and air-driven system equipment and in the contract agreement shall not be less than those specified in this code.
1.0.4 In addition to the requirements stipulated in this code, the installation quality acceptance of hydromatic, lubricating and air-driven system equipment also shall comply with those stipulated in the current relevant national standards.
2 Basic Requirements
2.0.1 The construction organization of metal mechanical hydromatic, lubricating and air-driven system equipment installation engineering shall be possessed of corresponding engineering construction qualification. At the construction site, corresponding technical standards for construction, and sound quality management system, quality control and inspection systems as well as the technical documents on construction organization design, construction scheme and operation design which have been examined and approved by the project technical director shall be available.
2.0.2 As far as the modification of construction drawings is concerned, the Notice of Design Modification or the Certificate of Technical Verification of the design organization shall be provided.
2.0.3 The inspection and acceptance of installation quality of hydromatic, lubricating and air-driven system equipment must adopt the measuring instruments which are qualified through verification and calibration.
2.0.4 Welders taking part in the welding work in the installation of hydromatic, lubricating and air-driven system equipment must pass corresponding examination and acquire the certificate of qualification, and be engaged in welding of their qualified examination items within the approved scope.
2.0.5 The installation of hydromatic, lubricating and air-driven system equipment shall be carried out according to the established procedures, shall be carried out with handing-over inspection with the work types of relevant disciplines and also be prepared with relevant records. The procedures in this discipline shall be subjected to quality control according to the technical standards for construction; at the end of each procedure, inspection shall be conducted and quality records shall be prepared. As long as the previous procedure is not approved through inspection, the next procedure shall not be commenced.
2.0.6 As for the secondary grouting of equipment and other concealed projects in the installation of hydromatic, lubricating and air-driven system equipment, before concealment the organizations concerned shall be informed by the construction organization to conduct acceptance and prepare acceptance documents.
2.0.7 The installation quality acceptance of hydromatic, lubricating and air-driven system equipment shall be carried out according to sub-item projects, sub-section projects and unit projects on the basis of the self-inspection of construction organization. The sub-section and sub-item projects of hydromatic, lubricating and air-driven system equipment should be classified in accordance with Table 2.0.7; the installation work of hydromatic, lubricating and air-driven system equipment in an independent process system, with total installation length of pipeline larger than or equal to 10,000m, may be classified as an unit project. If it is insufficient to form a unit project, the sub-section projects of hydromatic, lubricating and air-driven system equipment shall be incorporated into the unit project of the installation of mechanical equipment engineering to undergo acceptance.
