On September 18, 2018, the company cooperated with the gas group to organize an expert review meeting on " New Dajian Road Natural Gas Project". After discussion and verification by the expert group, the plan was approved.

This project is the first underground direct-buried pressure regulating device (Q=50000 m3/h) in Beijing , located in Block A3-2-1 of Zhujiang Investment and Development Company, Jinqiao Science and Technology Industry Base, Tongzhou District, which supplies gas for boiler room (140T/h) and surrounding areas. The newly-built medium-pressure A natural gas pipeline is connected to DN400 medium-pressure A natural gas pipeline on the south side of the boiler room (Majuqiao sub-high pressure A tank (30,000 m3/h) ) and can be used as a supplementary gas source in this area.

In this plan, the sub-high pressure regulating device covers an area of about 41.02 square meters, and the sub-high pressure A regulating station is equipped with a sub-high pressure A regulating device of 50,000 cubic meters. The filtration, metering and pressure regulation in the process flow are all directly buried underground. This plan is safe, technically reliable, reduces land use and noise and improves environmental compatibility.
