The service life of indoor hoses is generally less than 2 years. Hoses are easy to install, but need to be replaced regularly. Natural gas is mostly seamless steel pipes, stoves and natural gas pipelines.
Outdoor aluminum-plastic composite pipe can be used for a long time, and the installation of aluminum-plastic pipe needs special accessories, which is relatively troublesome and the cost is higher than that of hose. Aluminum plastic pipe can choose Rifeng, Jinde, Jinniu and other companies.
It should be noted that the aluminum-plastic pipe has three layers, the inner and outer layers are plastic, and the middle layer is overlapped or welded aluminum. It is easy to age when exposed to ultraviolet rays, so direct sunlight should be avoided, or PVC sleeves should be installed outside. Common specifications are 12 16, 14 18, 1620 and 2025.
Household natural gas safety knowledge;
1. If you use natural gas, you can't use other raw materials, such as bottled liquefied gas or coal.
2. The length of natural gas pipeline installed indoors is also limited to a certain extent, which cannot exceed two meters. If you choose a rubber tube, you can't go through the wall because of the material problem. Moreover, regular inspection is needed. If it is found to be aging and chapped, it needs to be replaced in time.
3. After each use of gas appliance, check whether it is turned off, and make sure there is no leakage before ventilation and ignition. When used in the kitchen, it is necessary to open the window or leave a certain gap to prevent natural gas leakage.
