Product introduction
High-Pressure Half-Coupling (Threaded) – Technical Specification
1. Product Definition
A high-pressure threaded half-coupling is a semi-circular pipe fitting designed to:
- Provide a branch connection on existing pipelines without full disassembly
- Enable high-pressure tapping (up to 6,000 psi) via male/female threads
- Serve as an economical alternative to welded outlets in maintenance-sensitive systems
2. Design Features
✔ Split-Socket Body: Clamps around existing pipe (no full-circumference welding required)
✔ Reinforced Collar: Prevents thread deformation under high torque
✔ Hex Flats: For wrench tightening during installation
✔ Optional Boss Design: Integrates a welding pad for secondary reinforcement
3. Applications
- Retrofitting: Adding instrumentation taps to existing high-pressure lines
- Hydraulic Systems: Branch connections for pressure gauges/valves
- Oil & Gas: Temporary test points on wellhead manifolds
- Power Plants: Steam line sampling ports
4. Installation Protocol
1. Surface Prep:
- Clean pipe surface & apply thread sealant
2. Clamping:
- Secure half-coupling around pipe with high-tensile bolts
3. Sealing:
- For non-welded versions: Use EPDM gasket between coupling/pipe
- For weldable types: Seal-weld the outer perimeter
4. Thread Connection:
- Tighten threaded component to specified torque (per ASME B31.3)
5. Advantages vs. Full Couplings
✓ No Pipe Cutting: Installs on live pipelines
✓ Faster Installation: 60% quicker than welded outlets
✓ Adjustable Positioning: Rotatable after initial clamping
6. Standards Compliance
- ASME B16.11: Threaded/socket weld fittings
- API 6A: Wellhead equipment compatibility
- NACE MR0103: Sour service compliance
Note: For permanent installations >3,000 psi, recommend seal-welding the half-coupling perimeter.
