Petrochemical Flanges

Zero Leak Integrity

Critical Service Flange Solutions

Stopping fugitive emissions at the source with advanced metal-to-metal sealing.

1. Petrochemical Flanges

Taper-Lok petrochemical flanges work where standard ANSI flanges fail, across refineries, LNG terminals, and gas processing plants. The metal-to-metal seal removes gasket dependency entirely.

2. Refinery Applications

Taper-Lok handles hydrogen service, sour gas duty, high-pressure steam, and high-temperature lines. Slight pipe misalignment is accommodated without rework or seal compromise.

3. Zero Gap Connector

Closes the physical gap with mating faces that contact completely and leave no emission pathway. Internal pressure tightens the seal rather than degrading it. Ideal for VOC lines.

4. CofferLok Advantages

CofferLok cuts standard flange profiles down to four bolts, a compact footprint, and a reusable metal-to-metal seal ring that holds across repeated maintenance cycles.

The Advantage

Why Choose Taper-Lok Petrochemical?

Taper-Lok petrochemical flanges deliver a self-energizing metal-to-metal seal that holds firm even in misaligned pipe conditions. Every joint is permanently leak-free, reducing fugitive emissions and eliminating costly unplanned maintenance.

For LNG flange connectors and oil refinery pipe fittings, the Taper-Lok design significantly reduces overall flange weight and face diameter, lowering material and installation costs.

Common Questions

Petrochemical FAQ

What are the flanges used in refineries?

Flanges in a refinery are mechanical fittings used to connect pipes, valves, pumps, and equipment. Taper-Lok compact flanges use a metal-to-metal seal to deliver a leak-free connection across high-pressure and high-temperature conditions.

How do connectors help reduce leakage?

Taper-Lok oil and gas connectors eliminate traditional gaskets entirely. The metal-to-metal seal creates a reliable joint that does not degrade over time, preventing fugitive emissions common in conventional systems.

Can they replace existing leaking flanges?

Yes. Taper-Lok petrochemical flanges are designed for straightforward retrofit into existing piping systems. The compact profile accommodates standard pipe schedules and pressure ratings with minimal disruption.

How do they reduce maintenance costs?

Because they require no gaskets or elastomeric seals, there are no scheduled seal replacements or re-torque procedures. The reliable seal holds throughout the asset lifecycle, reducing inspection frequency.
