Critical Applications for Flanges
Petrochemical & Refining
Used in high-temperature distillation columns and cracking units where secure, separable joints are required for maintenance.
Offshore & Subsea
RTJ (Ring Type Joint) flanges designed for high-pressure subsea pipelines and platforms where leak prevention is a safety priority.
Power Generation
Critical for boiler feed water lines and steam turbines in coal, gas, and nuclear power facilities.
Cryogenic Systems
Specialized low-temperature alloy flanges for LNG storage and transport, maintaining ductility at sub-zero temperatures.
Pulp & Paper Industry
Stainless steel and Duplex flanges resistant to acidic and alkaline slurries used in pulping and bleaching processes.
Cross-Country Pipelines
Large diameter flanges (up to 60") for water transmission and natural gas distribution networks across long distances.
