Is the gas riser in the kitchen a main pipe? Isn't it impossible to be indoors? How do you go straight through the floor (indoor)?

Dear, hello, I'm glad to answer for you, is the riser connecting the gas in the kitchen a main pipe? Isn't it impossible to be indoors? How do you go straight through the floor (indoor)?

A: No, the main gas pipes are located outside the floor structure and run through the entire floor. Indoor is the sub-pipeline for each household to use gas, which is directly connected from the main pipeline and connected to the gas hood. The installation standard for natural gas pipelines requires that the valves of natural gas pipelines installed indoors must be connected to the gas stove or plugged by oak, but the joint of a valve can be installed.

The hose should be replaced every one and a half to two years. When replacing the hose, use a hose for gas use, as it is dangerous if a non-gas hose is used, or if the hose is stiff or cracked.

The new house has a pipe well, and the old house does not have it through the interior.

No, the main gas pipes are located outside the floor structure and run through the entire floor. Indoor is the sub-pipeline for each household to use gas, which is directly connected from the main pipeline and connected to the gas hood.

The standard for the installation of natural gas pipelines requires that the valves of natural gas pipelines installed indoors must be connected to the gas stove or blocked, but the fitting of a valve can be installed. The hose should be replaced every one and a half to two years. When replacing the hose, use a hose for gas use, as if a hose for non-gas use is used, or if the hose is stiff or cracked, it is dangerous.

The national gas construction code stipulates that the building gas riser (the supervisor of the unit) can be on the outer wall of the building, or it can pass through the indoor floor slab, which is called "outdoor riser" on the outer wall and "indoor riser" through the floor slab, and the indoor riser usually passes through the well-ventilated kitchen position (well-ventilated means that there is a kitchen window leading directly to the atmosphere, and the kitchen is separated by a door). The specification also clearly stipulates that the gas pipeline is not allowed to pass through the bathroom, bedroom, and living room, and the gas pipeline shall not be encapsulated when the user decorates. At present, the regulations on the open kitchen connected to the kitchen and the living room (dining room) are relatively vague, for your own safety, it is best not to use the open kitchen, the kitchen has a door isolation, even in winter, you can open a little window ventilation, but the open kitchen will not necessarily open the window, the danger of gas is not only leakage, but also the consumption of oxygen and the exhaust gas produced during combustion (especially gas water heaters), in a closed space, it will cause hypoxic suffocation and carbon monoxide poisoning for a long time.

The installation of gas meters in the household through the pipes is generally in the corner of the kitchen or near the window.
