Since the start of the country's implementation of western gas, natural gas has become more important in our lives, and the role of natural gas in our daily life is also very important. Natural gas is generally transported through pipelines during transportation. Because natural gas is a high -risk gas, if natural gas leakage will occur if it is not handled, it will explode. Therefore, the requirements for the installation of natural gas pipelines are very strict. However, many friends do not understand the installation of natural gas very well, so I will give you the precautions for the installation of natural gas pipelines in detail.
Thestap of natural gas pipeline installation 1. Connections of gas pipelines and accessories can be welded as much as possible. 2. The vertical welding joints of the gas pipeline should be not less than 300mm from the side of the support, and the horizontal weld should be above the support. 3. Gas pipelines should take measures to eliminate static and lightning protection. 4. Gas pipelines with high carbon dioxide content such as blast furnace gas and turntable gas should not be buried. 5. When the overhead gas pipeline and other pipelines are laid, when the gas pipeline, the water pipe, the fuel pipe, and the gas gas are laid on the same pillar or trestle, the vertical spacing of the upper and lower layers should not be less than 250mm. Other pipelines that are placed with gas pipelines shall avoid the parts such as gas pipeline flanges, gate valves, and flipplaces of gas leaking gas. Power cables and wires should not be laid on the gas pipelines and brackets, except for cables for gas pipelines.
6. The minimum level of overhead gas pipes and the minimum level of the building is generally 5m, and in special cases, 3M. 7. Gas transportation competent pipes should not be less than 6m at low distance, and the supervisor of gas distribution should not be less than 4.5m; newly built and reconstructed dirty gas, semi -net gas, and net gas general pipes generally set up height, and the bottom to the ground to the ground The net distance is not less than 8m, and the small blast furnace can be lower than 6m. 8. The pipeline considers whether to set the drainter for the specific situation. If the drainter is set, the condensation water discharged should be treated. 9. Regularly measure the wall thickness of the gas pipeline and establish pipeline anticorrosive files.
The natural gas pipeline installation process 1. The first is to install outdoor gas pipelines and risers. 2. Before the user is preparing to stay in the kitchen, the original and photocopy of the ID card, real estate certificate (or house purchase contract) should be carried. In the place, improve indoor gas installation procedures. 3. When the user performs indoor decoration, the natural gas company will send someone to install the indoor pipeline. 4. The indoor decoration is completed. After the gas installation passes through the acceptance of the natural gas company, the ventilation can be enabled.
The above is the precautions for the installation of natural gas pipelines and other aspects of natural gas pipelines. Natural gas is very important in our lives, but the installation of natural gas pipelines is very important. If it is not qualified, it will cause natural gas leakage, and it will explode seriously. The consequences are dare not imagine. The above we have also shared the knowledge of natural gas pipeline installation very detailed. I hope our sharing can help everyone better understand the knowledge of natural gas pipeline installation.
