natural gas installation supervision and management is divided into two parts. One is a pressure pipeline with medium pressure or above, which belongs to the special equipment testing institutions of technical supervision and management departments, such as the boiler special equipment testing institute. One is a low-pressure pipeline, which belongs to the construction quality supervision organization of the construction management department. At the same time, according to the national regulations, the natural gas pipe network belongs to the municipal pipe network outside the community and the building inside, which need to be reported to the construction department for supervision and management. However, due to the overlapping scope of national standards, at present, only the medium-voltage pipe network is reported to the special equipment testing department for supervision and management. The supervision and management of construction is in name only.
