BX-152 Ring Joint Gasket – Low Carbon Steel (Zinc Plated) API 6A RTJ Sealing Ring

The BX-152 Ring Type Joint (RTJ) Gasket is a high-performance, pressure-energized metal sealing ring designed for use with API 6BX flanges in high-pressure oilfield applications. Engineered for systems operating at pressures from 10,000 PSI to 20,000 PSI, the BX-152 provides a robust, blowout-proof seal for wellheads, blowout preventers (BOPs), and high-pressure manifolds.

Manufactured from premium Low Carbon Steel (LCS), this gasket is precision-machined and subsequently zinc-plated (or coated with a similar corrosion inhibitor) to prevent oxidation and ensure integrity during storage and installation. The BX series features a unique geometry that allows for face-to-face contact between mating flanges. Once installed, the gasket is completely enclosed within the groove, making it highly resistant to vibration, temperature fluctuations, and mechanical shock.

The pressure-energized design means that as internal system pressure rises, the gasket is forced more tightly against the flange's sealing surfaces, further enhancing the metal-to-metal seal. Additionally, the BX-152 includes a standard pressure-equalizing vent hole to prevent pressure entrapment behind the ring, ensuring safe and predictable performance during decompression.

Features & Benefits

• Pressure-Energized Technology: Utilizes internal line pressure to increase the sealing force, ensuring a bubble-tight metal-to-metal seal under extreme conditions.

• Low Carbon Steel Construction: Offers the necessary ductility to deform into the flange groove for a perfect seal while maintaining high structural strength.

• Corrosion Protection: Finished with specialized zinc plating to resist rust and environmental degradation in field conditions.

• Integrated Vent Hole: Features a precision-drilled cross-hole to equalize pressure across the gasket, preventing fluid or gas entrapment in the groove.

• API 6A & ASME B16.20 Compliant: Machined to strict dimensional and hardness tolerances to ensure full interchangeability and to prevent damage to the mating flange faces.

• Face-to-Face Mating: Designed specifically for API 6BX flanges, allowing the flange faces to meet for a more rigid and protected connection.

Specifications & Technical Details

Applications

The BX-152 Low Carbon Steel Gasket is widely used in high-pressure drilling and production environments. Typical applications include critical connections on Blowout Preventer (BOP) stacks, wellhead assemblies, frac trees, and high-pressure choke and kill manifolds.

Quality Assurance

Each BX-152 gasket is manufactured under rigorous quality control standards. We perform strict hardness testing to ensure the ring is softer than the mating flange, preventing groove damage while ensuring the metal-to-metal seal is fully formed. Every gasket is visually and dimensionally inspected, with full material traceability provided to ensure safety and reliability in the field.
