Characteristics and precautions of gas steel pipe

Gas steel pipe A special kind of gas pipeline. Replacing traditional rubber hoses with metal gas hoses can solve the shortcomings of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and short service life.
First, the characteristics of gas steel pipe
Gas steel pipe is easy to install, reliable connection, corrosion resistance, no gas blocking, good flexibility, long service life, can be bent arbitrarily without deformation, no gas blocking and so on. The soft surface protective layer material is safer, easier to clean and beautiful. Stainless steel threaded metal hose has a service life of 8 years. In China's municipal pipe market, plastic pipes are developing steadily, PE gas pipes, PP-R gas pipes, UPVC gas pipes have a place, of which PE gas pipes have a strong momentum of development, and its use is also very wide.
Second, the need to pay attention to gas steel pipe matters
1. After the gas pipe is installed, it should be protected (especially when tiling). It is not allowed to dismantle, remove, touch, smash, squeeze or press the gas pipeline without permission to ensure that the gas pipeline is intact.
2. Remember not to seal the gas pipe, especially the main valve of the whole building and the gas meter in each user's home. If you need to decorate, it can be made into a valve cabinet or ventilation hole, and leave enough space for easy maintenance and security check.
3. Do not disassemble gas pipelines (including pipe fixing hooks or pipe clamps) and water heaters without permission. It should be installed by professional and technical personnel of the relevant gas company to ensure safety.
4. The room with gas pipeline can not be used as a bedroom, so as to avoid gas leakage, fire and endanger life safety. At the same time, flammable and explosive items cannot be stacked in the kitchen or room through which the gas pipeline passes.
5. The gas pipeline can be buried in the wall, not less than 10 cm from the ground. The gas pipe is not allowed to go through the wall, should not be too long, and the stove hose should not exceed 2m.
6. If the indoor pipeline has been filled with gas, when the indoor gas leak is found, first close the gas valve in front of the meter, open the indoor doors and Windows for ventilation, and prohibit all actions that may cause sparks, such as turning on the electrical switch. No open flame leak detection, outdoor call for help.
When the hard plastic pipe of the gas steel pipe is threaded, appropriate force should be applied to prevent the pipe mouth from twisting and cracking. The equipment is mainly composed of air compressor, air filter and welding gun. When using rigid PVC pipe as elbow, the method of sand filling hot bending should be selected. The heating temperature of the pipe is 130~140. The bending radius should not be less than 3 times the diameter of the pipe. During cold bending, the bending radius of the polyethylene pipe should not be less than 15 times the diameter of the pipe, otherwise the socket elbow should be used instead of the elbow.
When the gas steel pipe is connected to the steel pipe, the end of the steel pipe should be used as the socket, and the rust should be removed, polished and smooth before inserting the plastic pipe, and the 601 glue should be applied. After wetting, the interface can be coated with adhesive and 5 to 6 layers of glass cloth prepared by weight. General pipe fittings and fixed plastic joints welded in the field can also be reinforced in this way.
