Specifications for indoor use of PE gas pipes

PE燃气 管有老化、泄漏等现象,时间长了需要维修更换。 Do not install it indoors. The PE gas pipe introduced in the house has aging, leakage and other phenomena. It needs to be repaired and replaced after a long time.

PE燃气 放置于道路两旁地下,只要外层管质量有保障,放海底也没问题。 In the city, it is required to dig 3 meters deep and place PE gas pipes on both sides of the road and underground. As long as the quality of the outer pipe is guaranteed, it is no problem to put it on the sea floor.

PE燃气 管道断裂或管道密封不严泄露天然气,那后果不堪设想,出于安全考虑应做管沟,或将其埋入地下。 Natural gas is a flammable and explosive gas. If a PE gas pipeline breaks or the pipeline is not leaked tightly, the consequences are unthinkable. For safety reasons, a trench should be made or buried underground. According to the National Natural Gas Pipeline Installation Design and Acceptance Code , the main pipeline with a diameter above Φ40 should be located at 5OCM from the subsidiary branch pipeline.

管道施工时,以避免将管体焊缝朝向墙面,焊缝不明显的管道应事先做好标记。 When constructing gas pipelines, avoid directing the welds of the pipe body to the wall. Pipes with insignificant welds should be marked beforehand.

PE燃气 管道竖井内的铜管或不锈钢波纹管的安装,已在图件及其他管道施工完毕后进行,管道穿越竖井内的隔断板时应加套管,套管与管道之间应有不小于 5mm的间距。 The installation of copper pipes or stainless steel corrugated pipes laid in the vertical shafts of PE gas pipelines has been carried out after the construction of drawings and other pipelines. Casings should be added when the pipelines pass through partition boards in the shafts. Pitch of not less than 5mm.

Buried gas copper pipes or stainless steel corrugated pipes should not be in contact with various metals and wires; when unavoidable, insulation materials should be used to separate them. 道穿越楼板的孔洞宜从最高层向下钻孔,逐层以重锤垂直确定下层孔洞位置。 The hole of the PE gas pipeline passing through the floor should be drilled from the highest floor downwards, and the position of the lower hole should be determined vertically by a hammer.

The hose should be replaced once a year and a half to two years. PE燃气 管专用的胶管,如果使用非 PE燃气 管专用胶管,或者胶管有僵硬、龟裂就会发生危险 ;胶管的安全长度在1.5米以内,如果胶管超长并从墙体中或窗户玻璃中穿过,都存在安全隐患。 When replacing it, use a special PE gas hose. If you use a non- PE gas hose, or if the hose is stiff or cracked, it will be dangerous ; the safe length of the hose is within 1.5 meters. Or through the window glass, there are security risks.

Every time you run out of gas, just turning off the stove switch will not work. According to statistics, only closing the stove switch without closing the valve on the gas pipeline has become a major cause of gas accidents. Because once the aged hose or stove can not withstand the pressure, gas leakage will occur. Especially in winter, doors and windows are tightly closed, and the leaked gas cannot be emitted. When a certain amount is accumulated, an accident will occur. 提醒 ,使用完燃气后,除关闭炉具的开关外,还要牢记关闭燃气管线上的阀门。 To this end, we solemnly remind that after using the gas, in addition to turning off the stove switch, remember to close the valve on the gas pipeline.
