Coil Tubing Connectors

Internal Dimple Connector

Internal Dimple Connectors are essential to make-up coiled tubing bottom hole assemblies with the greatest torsional strength while maintaining no external upset against the CT string. During installation, a dimpling yoke and jig applies thousands of pounds of hydraulic force to dimpling buttons on the external CT wall that align with the dimples on the upper section (shank) of the connector. This process creates a strong, tight fit that transmits the tensile as well as the torsional forces applied.

External Slip Type Connector

The Slip Connector is designed to attach the BHA to the end of the coil and transfer the axial load using slips.

The Slip Connector is comprised of a top sub, slip, brass ring, and a bottom sub with desired connection. The dressed coil is stabbed into the connector and the bottom sub is rotated to start the tightening process. An overpull is then used to set the slips further and retightening the bottom sub then ensures no further movement.

Spoolable Dimple Connector

Spoolable dimple connectors are critical in pipe recovery operations as an emergency splice between two lengths of coiled tubing. The central part of the connector has a smooth thru-bore and notched exterior profile. The notches allow a plastic bending modulus equal to the coiled tubing while preserving the OD so that the connector can be passed through the injector chains and the stuffing box.

9 - Spoolable Dimple Connector

Technical Specifications

Engineered as an emergency splice solution, each configuration maintains CT bending modulus while preserving the original OD. The notched profile allows the connector to pass through injector chains and stuffing boxes during pipe recovery, maintaining full flow capacity and pressure integrity when CT failure means losing time downhole.
