After renovation, how to install the gas pipe at home?

The decoration treatment of gas pipeline in home decoration should be safe and beautiful first, especially easy to maintain and replace.

According to relevant regulations and personal experience and lessons, the following points are summarized:

1. The gas pipeline shall not pass through the bedroom and bathroom. Don't seal the gas main and gas meter. For example, the decoration must be well ventilated to facilitate maintenance and security inspection. For multiple gas appliance, branches of branch pipes must be clearly set for inspection, and the branch pipes should be laid openly as far as possible. It is suggested to branch the gas meter and control it separately.

2. If it is hidden, it must be located in a place that is not affected by external forces and the temperature changes greatly. Buried depth is not less than 10mm, and it must be marked well with perfect safety protection measures. The concealed part cannot have mechanical joints and should be insulated from other metal pipes or wires.

3. Pipes, fittings, valves, etc. Products that have passed the national standard inspection shall be adopted; Cleaning before installation to ensure cleanliness; It is not necessary to pass the pressure test before the pipeline is concealed. If the pressure is kept hidden, ventilation is the most convincing, and ventilation is often ignored, which is also an important measure to ensure safety and no air leakage. The pipeline shall not be damaged during concealed construction.

4. It is recommended to use the national standard stainless steel corrugated pipe thread connection for the soft connecting pipe connecting gas appliance. If rubber or plastic hose is used, it should be fixed when it is less than 2m. Please replace it regularly, about 1 year, to prevent aging and ensure safety.

5. When setting the control valve (tail valve) for the nearby protection of the appliance, the convenience of using, maintaining and replacing the hose should be considered first, and then the protection is safe and out of the way. It is suggested that the cooker should be placed at the outer edge of 4o㎝ above the lower left partition of the kitchen cabinet.

6, pay special attention to connect the water heater without looking at the sign, and connect it correctly, otherwise tap water will cause big trouble when it enters the trachea, and there are many lessons. Professionals need to check it many times and confirm it correctly before passing water.

7. When using gas appliance and pipes to pass through the room, it is recommended to install shutters or windows with normally open shutters in order to ensure ventilation.

8. Proper use and maintenance after decoration is also a guarantee of safety. Please accept regular security check, do not change relevant facilities at will, get into the habit of closing the gas tail valve when not in use, and close the gas valve in front of the instrument for a long time.

9. Learn relevant safety knowledge and how to deal with gas accidents. If gas leakage is found, first close the gas valve in front of the instrument, open the doors and windows for ventilation, and prohibit all actions that may cause sparks, such as turning on the electrical switch and calling for help outdoors.
