In the process of gas hose pipeline construction, in order to avoid the direction of the welding seam of the gas hose body facing the wall, the welding seam hose with inconspicuous welding seam should be marked accordingly in advance.
If the corrugated hose or copper pipe laid inside the pipe tree well can only be carried out after the drawing or other pipeline construction is completed, and the gas hose passes through the partition plate inside the shaft, a casing should be added.
At the same time, the distance between the casing and the gas hose should not be less than 5 mm, and the buried gas hose and bellows should not be in contact with other metals and wires.
If unavoidable, some insulating material should be used to isolate the two. Next, I will talk to you about some precautions in the process of gas hose construction, as well as maintenance methods after construction.
Some obvious gas hoses should be painted only after passing the inspection. If steel pipes are used for welding, they should be derusted before painting. All welds should be painted to two layers. primer.
Then, after being fully painted, galvanized steel pipe threads are used for connection. During the installation of other pipe fittings, a primer should be applied, and then two topcoats should be applied.
Generally speaking, the positioning of the gas hose is difficult. The arc-shaped gas hose is easy to cause some water-filled pipelines. The non-excavated pipelines are buried deeper, the intuitive performance is relatively poor, and the technical requirements are relatively low. high. Generally speaking, the gas hose should be replaced after one and a half to two years of use, and a special gas hose must be selected during the replacement process.
If you choose a non-dedicated gas hose, there may be a danger of the hose being stiff and chapped. The safety strength of the gas hose is within 1.5 meters. If the length of the gas hose is too long, and it needs to pass through glass windows and walls, there will be problems. certain security risks.
And every time you run out of gas, just turning off the stove switch is not enough. According to statistics, only turning off the cooker switch without closing the valve on the gas hose line has become a major cause of gas accidents.
Because once the aging hose or stove can not withstand the pressure, gas leakage will occur. Especially in winter, when the doors and windows are closed, the leaked gas cannot be released, and when a certain amount is accumulated, it will cause an accident.
After using the gas, in addition to turning off the switch on the stove, remember to close the valve on the gas hose.
