Organization and Functions of Supply Facilities

Facilities Organization and Functions

  • Pipe Network
    • Underground pipelines deliver high-pressure natural gas from production bases to consumers safely.
    • Pipe diameters range from 36 to 20 inches, and the maximum allowable work pressure is 6.87-0.98MPa (70-10 kg/cm²)
  • Supply Management Office
    • Based on the facilities, technology, inspection, and precision safety diagnosis standards for pipelines outside of wholesale gas production bases and supply offices, we operate three kinds of management offices with respective functions.
