Product Uses
1. Oil and Gas Pipelines
Flanges are widely used to connect pipelines in oil and gas extraction and transportation. They ensure secure, leak-proof joints that withstand high pressure and harsh environments.
2. Petrochemical Industry
In petrochemical plants, flanges connect various processing equipment, reactors, and storage tanks, providing reliable sealing under corrosive and high-temperature conditions.
3. Refineries and Processing Facilities
Flanges play a crucial role in refinery piping systems, enabling easy assembly and disassembly for maintenance while maintaining system integrity.
4. Offshore and Marine Applications
Designed to endure extreme marine environments, these flanges are used in offshore platforms and subsea pipelines, offering excellent corrosion resistance and mechanical strength.
Product Operate Guide
Before installation, inspect the flange and mating surfaces for cleanliness and damage. Align the flange properly and evenly tighten bolts using the recommended torque to prevent leaks. After installation, perform a pressure test to verify sealing integrity. Regularly inspect flange connections for loosening or corrosion to ensure safe and stable operation.
