CNG Pressure Reducing Station for Reliable Natural Gas Delivery

There is a CNG pressure reducing box in the workshop.
CNG pressure reducing box performs well in regulating and metering gas pressure.

CNG pressure reducing station also called CNG pressure regulating and metering station, is the abbreviation of compressed natural gas reducing station. It is a kind of gas pressure reducing stations. With the adjustment and optimization of energy structure, CNG (compressed natural gas) has got rapid utilization and development. The application process of CNG mainly consists five steps: First, get the wellhead gas or pipeline gas purified and compressed. Second, high pressure storage. Third. Transport to the sites. Fourth. Heat transfer and decompression. Five, Transmission. CNG pressure reducing station got widely used in natural gas applications. It plays an important role in CNG pressure regulation and transmission.

CNG pressure regulating and metering station is equipped with specialized cut-off device, which can automatically take reasonable security measures if an emergency occurs. Its remote monitoring system can let the users know clearly about working conditions of the regulator station. Pressure, temperature, flow and emergency shut-off valves of the station are all linked to the central control system. Various specifications of this type regulator station can meet different needs. This type gas pressure regulating and metering station has stable and reliable performance, it has been widely accepted by users at home and abroad.

There is a CNG pressure reducing station.
The specifications of CNG reducing station can be customized according to your specific requirements.
