City Looped High-Pressure Gas Pipelines Construction

We have participated in the first city-looped high pressure gas pipelines construction which ensures the sufficient gas supply.

High-pressure gas pipeline welding, radiographic examination and ultrasonic flaw detection
Railways, roads, bridges and rivers crossing
6.0 Mpa pressure test， pressure drop no more than 2%
4.6 Mpa air tightness test, pressure drop not more than 0.1Mpa
The First city looped high-pressure gas pipeline nationwide
Overall length: 96.6 KM
Pipe Size: 610 mm
Pressure: 4.0 Mpa
Annual gas transmission capacity: 3 billion m³
