gas steel pipeA special gas pipeline. Using metal gas hoses instead of traditional rubber 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.

Characteristics of 1. gas steel pipe

The gas steel pipe has the characteristics of convenient installation, reliable connection, corrosion resistance, non-gas blocking, good flexibility, long service life, and can be bent without deformation or gas blocking. The surface soft protective layer material is safer, easier to clean and beautiful. The service life of stainless steel threaded metal hose is 8 years. PE gas pipe in China's municipal pipe market, plastic pipe is developing steadily, PE gas pipe, PP-R gas pipe, UPVC gas pipe has a place, including PE gas pipe strong momentum of development is remarkable, its use is also very extensive.

Matters needing attention in 2. gas steel pipe

1. After the gas pipe is installed, it should be protected (especially when tiling). Do not dismantle, move, 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 decoration is required, it can be made into a valve cabinet or ventilation hole, and leave enough space for maintenance and security inspection.

3. Gas pipelines (including pipe fixing hooks or pipe clamps) and water heaters shall not be disassembled without permission. It should be installed by the professional and technical personnel of the relevant gas company to ensure safety.

A room with a gas pipe cannot be used as a bedroom to avoid gas leakage, fire, and life-threatening. At the same time, the gas pipeline through the kitchen or room can not be stacked flammable and explosive materials.

5. The gas pipe can be buried in the wall, not less than 10cm from the ground. Gas pipe is not allowed to pass through the wall, should not be too long, stove hose should not exceed 2m.

6. If the indoor pipeline has been filled with gas, when it is found that the indoor gas leak, first close the gas valve in front of the table, open the indoor doors and windows for ventilation, and prohibit all actions that may cause sparks, such as opening the electrical switch. Open fire leak detection is strictly prohibited, outdoor call for help.

Appropriate force should be applied to the hard plastic pipe of the gas steel pipe during threading to prevent the nozzle from twisting and cracking. The equipment is mainly composed of air compressor, air filter and welding gun. When making elbows with hard PVC pipes, the method of sand filling and hot bending should be selected. The heating temperature of the pipe is 130~140, and the bending radius should not be less than 3 times the pipe diameter. The bending radius of the polyethylene pipe during cold bending should not be less than 15 times the pipe diameter, otherwise the socket elbow should be used instead of the elbow.

　　gas steel pipeWhen connecting with the steel pipe, the end of the steel pipe shall be used as the socket, and the rust shall be removed, polished and coated with 601 glue before inserting the plastic pipe. After infiltration, the interface can be coated with adhesive and 5-6 layers of glass cloth prepared by weight. General pipe fittings and field welded fixed plastic joints can also be reinforced in this way.
