Taper-Lok® Ball Misalignment Flanges

Up to 10° Angular Compensation

Handling complex subsea pipeline and manifold offset geometry with zero pressure reduction.

1. Angular Compensation

Subsea and underground pipeline routes rarely meet perfectly. The Taper-Lok® Ball Misalignment Flange accommodates up to 10 degrees of angular misalignment, removing the need for costly field measurements and spool re-fabrication.

2. Full Structural Capacity

Traditional ball joints require pressure de-ratings at high angles. The Taper-Lok® misalignment flange maintains its full design pressure rating and tensile/bending structural capacity even when fully offset at 10 degrees.

3. Spherical Metal Seal

Features a custom spherical-nose metal-to-metal sealing geometry. As internal line pressure builds, it acts directly on the seal lips, forcing them tighter into the flange pocket to prevent leaks.

4. Diver & ROV Operations

Designed to be ROV and diver friendly, our misalignment flange simplifies pipeline tie-ins. The outer flanges slide and tilt easily, making connection adjustments safe and fast underwater.

Forged for Severe Misalignment

Designed and qualified for deepwater pipelines, risers, and manifold jumpers where thermal expansion or seabed shift causes continuous pipe movement.

Manufactured from forged carbon steel or high-strength duplex alloys, the Taper-Lok® misalignment flange is qualified for HPHT and sour gas environments.

Misalignment FAQ

How does the ball misalignment flange maintain its seal at an angle?
The seal ring has a spherical outer face that mates with a matching spherical socket inside the flange body. This allows the flange to tilt up to 10 degrees while the seal ring remains in full contact with the seating surfaces.
Is the misalignment set permanently during installation?
Yes. Once the flange is aligned at the required angle, the bolts are tightened to full pre-load. This locks the connection into a rigid joint that behaves like a solid weld neck flange, resisting external forces.
Does this require specialized installation tools?
No. The flange uses standard studs and nuts. Standard hydraulic torquing tools are used to tighten the connection, making it straightforward for standard marine and construction crews.
