Product details

Large flanges are widely used for natural gas pipeline connections, especially in high-pressure, long-distance, or large-diameter natural gas transmission systems. As a critical component for pipeline connections, large flanges ensure the sealing, strength, and reliability of the pipeline system, making them suitable for various operating conditions in natural gas pipelines.

Specific applications of large flanges in natural gas pipeline systems include:

  • Long-Distance Natural Gas Pipelines: Used to connect long-distance gas transmission pipelines (such as the West-East Gas Pipeline), ensuring the stability of the pipeline during high-pressure (10–20 MPa or higher) and long-term operation.
  • Natural Gas Processing Plants: In natural gas compression stations, distribution stations, or purification plants, used to connect pipelines with valves, filters, metering devices, and other equipment.
  • City Gas Distribution: In urban gas pipeline networks, used to connect main pipelines with branch pipelines, or with the interfaces of pressure regulating stations and storage and distribution stations.
  • Offshore Natural Gas Platforms: In offshore natural gas extraction and transportation, large flanges are used to connect subsea pipelines with platform equipment, requiring resistance to seawater corrosion and high pressure.
  • LNG (Liquefied Natural Gas) Facilities: In LNG receiving stations or storage tank systems, used to connect cryogenic pipelines, requiring compliance with low-temperature toughness requirements.
