Onshore Completion Equipment
Casing Heads/Casing Spools
- Models: C-22, C-29 (light/heavy load), Slip-Type Casing Heads
- Features: Compliant with API 6A standards; straight-through design avoids wear and supports BOP testing; slip-type requires no welding for quick installation (30 minutes).
Casing Hangers
- Models: C-21 (light load), C-22 (medium load), C-29 (heavy load)
- Features: Slip self-energized sealing; temperature resistance from -46°C to 121°C; compatible with API casing sizes; high reliability of H-type seal boxes.
Tubing Heads & Tubing Hangers
Tubing Heads
- Models: Single String (TCM), Dual String (TC-60)
- Features: Single String (TCM): Compatible with TC-1A-FN hangers; side outlets support production pipeline connection.
Dual String (TC-60): Segmented suspension design, suitable for high-pressure dual-string completions.
Tubing Hangers
- Models: Elastomer-Sealed TC-1A-FN, Metal-Sealed (M2M)
- Features: Elastomer-Sealed TC-1A-FN: Optional downhole safety valve control lines.
Metal-Sealed (M2M): Suitable for high-pressure (15,000 psi / 103.5 MPa) and corrosive environments.
