Special tools should be used for the joint of natural gas pipes, and if the joint has been ready, you can connect it yourself, but you must use soapy water to test whether it is bubbling to avoid air leakage.

Interfaces on natural gas pipelines. First of all, it is necessary to look at the outside of the gas meter, or on the inside. No one outside the table is allowed to move, only professionals to repair, if in the table, you have strong personal hands-on ability, you can connect it yourself, after the connection to use the washing water to try it, check whether there is air leakage?
Stay safe.

Hello, it takes two tubes. Gas stoves and gas water heaters use the same air pipes. Installation Method:
1. Close the gas valve, plan the location of the gas stove and direct gas water heater in advance, and fix the gas stove and direct gas water heater after installation; The gas pipe is then connected to the gas meter. 2 Connect the dedicated 3-way valve to the outlet pipe of the gas meter. 3. From the special three-way valve of the gas pipeline, connect the pipeline of the gas furnace and the gas water heater in turn, and the length of the pipeline should be relaxed with margin, and it should not be too straight.
4. Connect all the gas pipes connected to the gas water heater and the air inlet of the gas stove and fix them with special locks. 5. Take back the cold water pipe and hot water pipe of the gas water heater, align it with the indication sign, and tighten it; An Sleepy Bi installed a gas water heater and a gas stove.

Summary. It cannot be used universally because the composition of the two gases is different. Natural gas is a flammable gaseous hydrocarbon, which is a natural gas that accompanies the extraction of oil, which is divided into dry gas and moisture gas according to different compositions, and the methane content in dry gas is more than 80%-90%.
In addition to methane, moisture is also bound by ethane, propane and other gases. The main component of coal gas is carbon monoxide, which is a colorless and odorless gas that is insoluble in water and has a blue flame when burned. However, carbon monoxide is highly toxic, and if the concentration of carbon monoxide in the air is too high, it is likely to cause necrosis of body tissues due to lack of oxygen, which may seriously endanger human life.
Natural gas is a non-toxic gas with a smaller density than air, which is not easy to accumulate into a first-class gas, and is safer than coal gas. This is also a natural gas pipe and a gas pipe.

Natural gas is a flammable gaseous hydrocarbon, which is a natural gas that accompanies the extraction of oil, which is divided into dry gas and moisture gas according to different compositions, and the methane content in dry gas is more than 80%-90%. In addition to methane, moisture is also combined with ethane, propane and other gases.
The main component of coal gas is carbon monoxide, which is a colorless and odorless gas that is insoluble in water and has a blue flame when burned. However, carbon monoxide is highly toxic, and if the residual carbon concentration in the air is too high, it is likely to cause necrosis of body tissues due to lack of oxygen, which may seriously endanger human life. Natural gas is a non-toxic gas with a smaller density than air, and it is not easy to accumulate into ** gas, which is safer than coal gas.
This is also a natural gas pipe and a gas pipe.
When I was decorating, I buried the gas pipeline, I forgot that I don't have gas here, I can only use gas, so can the gas pipeline be connected?
I can't pick it up. The tube must be changed.

If the device does not need to be moved, it is better to have a threaded connection.
Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.). The definition of "natural gas" that has long been used is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas.
Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.
Natural gas is contained in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcanic gas and biogenerated gas, and a small amount also comes from the coal seam cavity. It is a high-quality fuel and chemical feedstock.
The main use of natural gas is as fuel, which can make carbon black, chemicals and liquefied petroleum gas, and propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low-molecular-weight hydrocarbons and non-hydrocarbon gases.
With the accelerated implementation of the natural gas reform, the "13th Five-Year Plan" vigorously promotes the gradual approach of natural gas development expectations, and the recent cold weather has increased the use of natural gas, the development of natural gas will usher in a historic opportunity.

The gas wall-hung boiler and gas stove are connected to special pipes and joints.
1. A self-closing valve is installed at one end for connecting the stainless steel bellows and connecting the gas stove (special for bellows). The general use size is 16mm (1 2"Pipes, fittings, valves.
2. Install a special angle valve for gas at one end, connect the gas aluminum-plastic composite pipe, and then connect the gas wall-hung boiler. The general use size is 20mm (3 4"Pipes, fittings, valves.

Natural gas pipeline joints are divided into 20, 25, 32, 40, 50 and 63 specifications in terms of size.
Chemical composition] The main components of natural gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane and butane, in addition to hydrogen sulfide, carbon dioxide, nitrogen and water vapor and a small amount of carbon monoxide and trace amounts of rare gases, such as helium and argon. Under standard conditions, methane to butane exists in a gaseous state, and pentane above is a liquid. Methane is the shortest and lightest hydrocarbon molecule.
Main classification] In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases. Natural gas in a broad sense refers to all naturally occurring gases in the earth's crust, including oilfield gas, gas field gas, mud volcanic gas, coalbed methane and biogenerated gas.
According to the phase state of natural gas in the ground, it can be divided into free state, dissolved state, adsorbed state and solid hydrate.
That is, the pressure of natural gas transported by the external trunk pipeline is very high, about dozens of kilograms, and the natural gas pressure used at home needs to be relatively low, about 3kpa, so an intermediate device is needed to adjust the natural gas pressure of the pipeline for civil use. These devices are placed in the house and are called pressure regulating stations.
The main component of natural gas is methane.
The molecular weight is 16; The main component of air is nitrogen. >>>More
Sihe Village, Wen'an County, Langfang City, Hebei Province installed 12,000 natural gas directly in 2019, and returned 1,000 yuan of subsidized gas.
First of all, why don't old people like to use it? Before the installation of natural gas in my home, cooking was always burning, and corn stover was used to burn. But in recent years, with the promotion of straw returning to the field, there is almost no corn stalk to burn, so I can only go to other people's fields in the autumn to pick pear branches to dry. >>>More
Electric underfloor heating is better. I've been preparing to decorate for the past two days, and I'm also looking at floor heating. After looking at water floor heating and electric floor heating, I feel that electric floor heating is better. >>>More
