 6.1.1 General provisions pipe installation shall meet the following conditions: 6.1.1.1 and pipeline-related civil works have been tested together Geha Xi-line analytical instruments, to meet the installation requirements, and has been handing. 6.1.1.2 machinery and pipe connections have to find positive qualified, fixed completed. 6.1.1.3 piping components and pipe supports, have been inspected. 6.1.1.4 pipes, fittings, valves, and other hash conductivity meter, internally clean hash turbidity, no debris. Within the possession of the special requirements of the pipeline, its quality has been consistent with the provisions of the design documents. Such as degreasing, internal corrosion and lining 6.1.1.5 related processes must be completed prior to the installation of the pipeline has been completed. 6.1.2 flanges, weld and other connections should be set for easy maintenance, and not close to the wall, floor or rack. 6.1.3 degreased piping components, and must be strictly checked before installation, without traces of oil pollution. 6.1.4 pipeline crossing the road, when the wall or structure, should be added protective sleeve or masonry culvert. 6.1.5 buried pipeline corrosion pressure test, it should promptly backfill, compaction in layers, and "(closed) record covert project" form to fill in Section A.0.4 A provision of this Article shall regulate the Appendix, for the hidden works acceptance. Mild steel, copper, aluminum and other metal gaskets, when the factory is not annealed, the annealing process should be carried out prior to installation. Hot or cold state fastening fastening should maintain the operating temperature after 2h conduct. 6.3.10.3 fastening bolts when the pipe, pipe maximum internal pressure should be determined according to the design pressure. When 6MPa design pressure is less than or equal to the thermal state fastening shall be the maximum internal pressure 0.3MPa; when the pressure is greater than based sauce 6MPa, thermal state fastening the maximum internal pressure should be 0.5Mpa. Cold fastening should conduct relief. 6.3.10.4 tightening should be moderate and should secure technical measures to ensure the safety of operating personnel. Plus multi-pad interface and other methods to eliminate the gap end face, oblique, wrong port or different heart defects. 6 the following shall apply hot or cold state fastening fastening: 6.3.10.1 love fastening pipes, cold temperature should be tightened in accordance with Table 6.3.10.
