The special pipe materials for natural gas are as follows:

1, domestic natural gas pipe.

Made of high-quality PVC and synthetic materials, soft and flexible, safe and reliable, better pressure resistance, good weather resistance, excellent sealing.

2. Aluminum-plastic composite pipe for gas.

Special aluminum-plastic pipe natural gas pipeline material is aluminum-plastic composite pipe to welded aluminum pipe as the middle layer, the inner and outer layers of polyethylene plastic, aluminum layer inside and outside the use of hot-melt adhesive bonding, through a special mechanical processing method composite into one natural gas pipeline material.

3, 40 chromium seamless steel pipe.

40 chrome seamless steel pipe and round steel and other solid steel, compared to the same bending and torsion strength, the weight is lighter, 40 chrome seamless steel pipe is a kind of economic cross-section steel, used as a pipeline for transporting fluids.

4, spiral pipe for natural gas.

National standard spiral steel pipe referred to as 9711.1 spiral steel pipe, 9711.2 spiral steel pipe, material classification: 16Mn material spiral steel pipe, Q345B spiral steel pipe, L245 spiral steel pipe, L360 spiral steel pipe, X40-X80 spiral steel pipe, is mainly used for the oil, natural gas industry to transport combustible and non-combustible fluids and steel structures.

5, metal hose for gas.

This new type of pipe has the advantages of strong connection, corrosion resistance, long life, easy to install, easy to construct, safe to use, flexibility and good sealing. Gas metal hose can be displaced with the movement of the earth's crust, used for natural gas, liquefied petroleum gas and other sources of gas into the gas appliance pipeline connection, higher security.

China was the first country to use wood and bamboo pipes to transport natural gas. 1600 years ago, around the Ziliujing gas field in Sichuan Province, not only in the laying of pipelines on flat ground, and "high mountain, low into the ground", "digging a ditch at the bottom of the river to set up the water pipe, chiseled stone for the groove covered with it". The modern gas transportation pipelines in China are mostly centralized. China's modern natural gas transportation pipelines are mostly concentrated in Sichuan Province, the main source of natural gas.

Extended information:

Usage

1, the gas pipe is installed, to be properly protected (especially in the tiling), shall not be privately dismantled, moving, touching, smashing, squeezing, pressing the gas pipe, in order to ensure that the gas pipe is intact and unbroken.

2, remember not to seal the gas pipe, especially the entire building of the valve and the gas meter of each user's home, such as the need for decoration can be made into a living cabinet or leave ventilation holes, to reserve enough space for maintenance and security checks.

3, do not privately dismantle and install gas piping (including piping fixed hooks and nails or pipe cards) and water heaters, should be installed by the relevant gas company's professional and technical personnel to ensure safety.

4, there is a gas pipeline room can not be used as a bedroom, in order to avoid gas leakage, fire, endangering life safety. At the same time, the gas pipe through the kitchen or room can not be stacked flammable and explosive substances.

5, the gas pipe can not be buried in the wall and not less than 10cm from the ground. gas pipe is not allowed to go through the wall and should not be too long, the stove hose no more than 2 meters.

6, if the indoor pipeline has been with gas, found that the indoor gas leakage, first of all, you should turn off the gas valve in front of the table, open the indoor doors and windows ventilation, prohibit the opening of electrical switches and all other behaviors that may cause sparks, prohibit open flame leakage, to the outdoors to dial the telephone number for help.
