Upstream & Offshore (HPHT & Subsea)

Operating in harsh marine environments, subsea depths, and High-Pressure High-Temperature (HPHT) wellhead zones demands ultimate mechanical reliability. Equipment is subjected to hydrostatic ocean pressures, intense structural flexure, dynamic topside vibration, sour gas (H2S) exposure under NACE MR0175 / ISO 15156, and wellhead working pressures reaching up to 20,000 PSI.

Primary Application Areas

API 6A wellhead Christmas trees, subsea BOP stack connections, offshore production risers, subsea manifolds, choke-and-kill manifolds, high-pressure mud pumps, and topside separation units.

Common Flange Types & Standards

API 6A Type 6B & 6BX Flanges

Heavy-duty, extreme-pressure flanges engineered for wellhead, BOP, and Christmas tree assemblies.

ASME B16.5 / B16.47 Weld Neck Flanges (WN - RTJ Facing)

Standard high-pressure connections for topside process manifolds and riser piping.

Engineered Gasket & Sealing Selection

API Spec 6A & 17D Ring Type Joint (RTJ) Gaskets

Solid metal RX, BX, and pressure-balanced SRX / SBX subsea profiles machined in Inconel 718, Super Duplex S32750, and 316L SS with strict hardness verification to force plastic seal deformation without damaging expensive groove faces.

API 6FB Fire-Safe Flange Isolation Kits (FIK - TX-ISOPRO)

High-dielectric G10/G11 Glass-Reinforced Epoxy (GRE) retainers with spring-energized PTFE seal elements engineered for splash-zone atmospheric protection and subsea Cathodic Protection (CP) isolation.
