External slip connectors grip the outer diameter of the coiled tubing using slips to transmit axial and torsional loads while maintaining internal flow. They are field-installable and suitable for standard interventions like cleanouts or stimulations.
Internal slip connectors engage the inner diameter of the coiled tubing with slips or collets, preserving the external profile and reducing drag in deviated wells. They support high-pressure applications with full-bore access for efficient fluid circulation.
Grapple connectors use mechanisms that bite into the coiled tubing for secure holding under dynamic loads, with options for thermal compensation in high-temperature environments. They handle vibration and provide unrestricted internal diameter for better flow during operations.
Dimple connectors create a mechanical lock by crimping dimples into the coiled tubing, often using grub screws for added security. They offer a permanent hold ideal for high-tensile and extended-reach applications with minimal risk of slippage.
Roll-on connectors are swaged or rolled onto the coiled tubing to provide a friction-fit connection that accommodates varying tubing weights and transitions. They are versatile for mismatched setups and easy to redress for reuse in the field.
Grub screw connectors secure the coiled tubing using threaded grub screws, often combined with slips for even load distribution and rotational locking. They enable quick assembly and disassembly, with high shear resistance for temporary interventions.
Collet-type connectors use expandable collets to grip the coiled tubing evenly, allowing for releasable connections with metal-to-metal seals where needed. They are adjustable for different sizes and reusable during frequent tool changes while maintaining pressure integrity.
Specialized connectors address specific needs like spooling large-diameter tubing or self-aligning for efficient makeup in hot wells. They reduce rig time and enable longer strings without welding, enhancing operational efficiency.
