Clamp Type Connectors (Hub Connectors)
High-pressure clamp-type hub connector systems for offshore wellhead platforms, flowlines and manifolds — butt-weld hubs, metal seal ring, clamp and stud bolts/nuts. A compact, fatigue-resistant alternative to flanged connections.
- Metal-to-metal sealing
- Compact and lightweight compared with conventional flanges
- Fast make-up and break-out
- Spool replacement without hot work at the connector
- Axial-load and bending-moment design verification
- BV / DNV / TÜV third-party inspection available
High-pressure clamp-type hub connector systems for offshore wellhead platforms, flowlines and manifolds — butt-weld hubs, metal seal ring, clamp and stud bolts/nuts. A compact, fatigue-resistant alternative to flanged connections. Meritus Technology is a supplier in China and sourcing partner for pressure-containing oil & gas production piping equipment. Standards: ASME VIII, API 6A, ASME B16.25, NACE MR0175 / ISO 15156. Confirm design code, material, pressure–temperature envelope, fluid composition, corrosion/erosion allowance and connection interfaces before manufacture. Approval and registration status relates to the relevant manufacturing partner, product scope and purchasing entity; project-specific evidence and current validity are confirmed at quotation. These references do not imply that every product is approved by every listed organization or that Meritus holds direct approvals.

Preparation Requirements
Review approved drawings, pressure–temperature ratings, fluid compatibility, inspection records and site permits. Isolate, depressurize, drain and verify zero stored energy before opening any pressure boundary.
Installation Steps
- 1Verify material identity, dimensions and pressure rating against the approved order
- 2Inspect sealing faces, screens, cushions or closure parts as applicable
- 3Align piping without forcing connections or introducing unapproved loads
- 4Fit the specified new seals and tighten fasteners in the approved sequence to the specified torque
- 5Check vents, drains, differential-pressure tappings and safety interlocks where fitted
- 6Complete the approved leak/pressure-test and commissioning procedure
- 7Record installation results and hand over maintenance instructions
Required Tools & Equipment
Certified lifting equipment, calibrated torque tools and project-approved alignment and pressure-test equipment.
Safety Requirements
Never loosen a connector or open a closure under pressure. Follow isolation, depressurization, gas testing and permit-to-work procedures.
Technical Support
Quotation-stage review of service conditions, drawings, codes, materials and manufacturing-partner approval requirements.
Field Service
Installation-support scope and site attendance agreed in the purchase order.
Training Programs
Equipment-specific handling, closure, screen/cushion replacement and maintenance guidance as applicable.
Documentation
Approved drawings, material certificates, weld traceability, NDT, pressure-test reports and project-specific approval evidence as ordered.
