"We carried out natural gas replacement construction some time ago, everyone has been looking forward to it for a long time, and this time we finally want to use natural gas, and we are very happy." However, we found that the replaced tubes are exposed, everyone can not help but be a little worried, long-term wind and sun, can ensure safety? Mr. Zhao, a citizen, said that neighbors had some doubts about such a construction method.
The construction of natural gas pipeline network is a major people's livelihood project, which is not only related to the quality of life of the people, but also a basic project to improve urban functions, improve the urban environment and enhance the quality of the city. In the process of natural gas replacement construction, many old residential areas basically use outdoor riser construction methods, why use this construction method?
The relevant person in charge of China Resources Gas said that indoor transformation and outdoor riser are common practices for riser transformation, which are in line with the current "Urban Gas Design Code". The riser construction method is finally determined by comprehensively considering the service life, pipeline material, corrosion, emergency repair record and other factors to ensure that the safe gas needs of the public are met.
In addition, on the basis of following the principle, the determination of the construction method also needs to be combined with the actual situation of the site, according to the actual situation of the riser, if there is a long service life, serious corrosion, multiple emergency repair records, etc., the external riser construction method should be adopted.
