The self use gas metering and pressure regulating system in gas transmission stations is suitable for natural gas distribution stations, metering stations, storage and distribution stations, pressure regulating stations, and other stations with manned or unmanned operation and manned duty.

The self use gas metering and pressure regulating system in this station has high requirements for the heater. Firstly, special explosion-proof performance and protection requirements are required, and at the same time, the manufacturing of the equipment casing is also required. Heaters generally use indirect or direct electric heaters (furnaces), and the heating speed, heating temperature, and safety protection measures such as preventing dry burning of electric heaters directly affect the safety of the system.

System features:

a. Gas heating generally adopts electric heating method, which is divided into direct electric heaters (furnaces) and indirect electric heaters (furnaces);

b. Adopting a cut-off pressure regulating valve, it has the characteristics of stable pressure and excellent closing performance at low flow rates;

c. Adopting safety protection measures with dual safety emergency shut-off valves;

d. High voltage regulation accuracy of ± 1% and wide regulation ratio;

e. Equal percentage characteristic (logarithmic characteristic);

f. The system safety cut-off response time is less than 1 second;

g. The system can also be configured with functions such as automatic shut-off, remote valve position transmission, and valve position indication (local and remote);

h. Special flow meters are used for small flow metering applications.

Typical performance examples: famous pipeline gas transmission stations and metering stations such as Seninglan, Shaanxi Beijing Line, Cangzi Line, Shanwu Line, West East Gas Pipeline Jining Connection Line, West East Gas Pipeline Expansion Project self use gas, Zhongwu Line, etc.
