Oil & Gas Solutions
Engineered for upstream, midstream, and downstream pressure and reliability.
Overview
The oil and gas industry demands the highest standards of flange engineering. From subsea blowout preventers at 15,000 feet to refinery process piping, every connection must withstand extreme pressures, corrosive fluids, and demanding environmental conditions. Our flanges support wellhead systems, pipeline infrastructure, separation equipment, and downstream processing.
Applications
Wellhead and subsea completions
Pipeline distribution and transmission
Separator and pressure vessel connections
Furnace tube systems in refineries
Glycol/amine treater service
LNG and cryogenic systems
CO2 sequestration and injection

Typical Service Specifications
Flanges in oil & gas typically operate at 600-2500 PSI with temperatures ranging from -50°F (LNG service) to 1000°F (furnace outlet). Sour service applications require NACE MR0175/ISO 15156 compliance. Material Test Reports with heat number traceability and pressure-temperature ratings are mandatory.
