Flange
Product Description
As the core component of connecting pipelines and equipment, flanges are widely used in industrial and civil fields that require sealing, pressure bearing or easy disassembly and assembly. The following are its main application scenarios:
1. Petrochemical and natural gas
Oil and gas transmission pipelines: Butt-welded flanges (Class 300 and above) connect high-pressure oil and gas pipelines to ensure sealing (such as API 6A standard).
2. Energy and power
Thermal power plants: High-pressure steam pipelines use ring joint (RTJ) flanges with a temperature resistance of ≥540℃ (such as ASTM A105 material).
Nuclear power plants: Stainless steel flanges (316L) are used in cooling water systems to resist radiation corrosion.
3. Construction projects
Steel structures: Flanges splice bridge trusses and building support columns (Q235B flat welding flanges).
4. Shipbuilding and marine engineering
Hull pipes: 316 stainless steel flanges resistant to salt spray corrosion are used to connect the ballast water system.
