Mission-Critical Equipment for the Energy Sector
Oil and gas exploration, processing, and transportation demand heavy-duty equipment capable of enduring immense pressure, abrasive fluids, and extreme temperatures. Openex Metal Fabrication is an established partner for the global energy sector, combining 180 acres of massive fabrication capacity with the strict quality controls required to build to API, ASME, and global classification codes.
Whether you require heavy structural weldments for offshore platforms, precisely machined gas compression skids, or enormous high-pressure reactor vessels for refineries, we act as a complete, under-one-roof contract manufacturer.
O&G Sectors We Support
Upstream
Exploration & Production
Operating on land and subsea, upstream equipment requires exceptional fatigue resistance and structural integrity. We specialize in heavy marine plating and weldments designed to survive harsh ocean dynamics.
- Jack-up rig legs and offshore tubulars
- Subsea manifolds, templates, and PLEMs
- Blowout Preventer (BOP) handling structures
- Custom heavy-duty mud tanks and skids
Midstream
Transportation & Storage
For pipelines, pumping stations, and bulk storage, continuous flow relies on heavy walled infrastructure. We manufacture large-scale components requiring advanced forming and critical pipe welding.
- Gas compression packages and massive base skids
- Custom large-diameter flanges and pipeline manifolds
- Pig launchers and receivers
- Heavy walled pressure vessels and separators
Downstream
Refining & Petrochemical
Refineries handle extreme heat, volatile chemicals, and immense pressures. We utilize advanced heat-resistant and corrosion-resistant alloys, along with explosive cladding, to build heavy-duty processing internals.
- Massive tube sheets (up to 8,000 mm diameter)
- Heat exchanger shells and complex baffle assemblies
- Reactor vessels, columns, and towers
- Industrial vacuum chambers and energy storage tanks
Strict Adherence to QA/QC & Standards
The O&G sector requires absolute traceability and certified material handling. We operate highly equipped internal inspection facilities managed by ASNT certified NDT technicians.
- ✓ Extensive Non-Destructive Testing (NDT): 100% full-penetration joint inspections via Ultrasonic Testing (UT), Radiography Testing (RT), Magnetic Particle (MPI), and Penetrant Testing (PT).
- ✓ Welding Procedures (WPS/PQR): Over 1,000 qualified welding procedures strictly following ASME Section IX, API, AWS D1.1, and DNV rules. Multi-pass SAW for ultra-heavy plate connections.
- ✓ Post-Weld Heat Treatment (PWHT): Massive on-site stress relief furnaces ensure large O&G pressure vessels maintain their required structural mechanics after intensive fabrication processes.
- ✓ Dimensional Validation: Laser trackers and large-scale CMM machinery to guarantee critical flange sealing faces and machine beds sit absolutely flat to sub-millimeter tolerances.
