ULTRA-DUTY-TWIN-FLAPPER-CHECK-VALVE
The Ultra-Duty Cartridge Type Twin Flapper Check Valve acts as a dual barrier within the tool string avoiding any well fluid backflow through the coiled tubing. The flapper cartridges that fit into the housing allows and efficient pressure sealing due to the combined elastomeric and metal interaction, providing efficient low and high pressure sealing and requiring a simpler redress.
The CE TFCV Cartridges are designed as a single-piece body to reduce the number of potential leak paths and provide reliable pressure testing capabilities. The elastomeric seal is far removed from the flow path to maximise seal life.
The CE Ultra Duty Twin Flapper Check Valves are rated up to 15,000 PSI and feature backup rings on internal O-ring seals to increase the high-pressure protection.
FEATURES AND BENEFITS
- 15,000 PSI rated
- Backup rings on O-ring seals
- Single piece cartridge body to reduce leak paths and increase pressure testing reliability
- Dual elastomer and metal-to-metal seals
SLIP-DIMPLE-CONNECTOR
The CE slip Dimple Connector combines the strength of the Slip and the Dimple connectors to form a very strong connector assembly capable of transmitting high tensile loads and torque capabilities during operations. A pattern of set screws in the body of the connector is locked into pre-formed dimples made on the outside of the coiled tubing using a DTI dimple tool. In addition, a tapered slip with internal teeth bites onto the tubing and pulls up into a tapered bowl.
RUPTURE-PLUG-CIRCULATION-VALVE
The CE CV Rupture Plug allows the circulation of fluid through the CT tool under normal operating conditions. By increasing the CT pressure to a predetermined value, the rupture plug will blow out, allowing to open a flow path from the tool string to the well. This capability is useful when a CT circulation flow path needs to be opened to the well below a tool requiring a drop ball whilst leaving the full tool string I.D. clear for other required operations.
ROLL-ON-CONNECTOR
The CE Roll On Connector forms a sealed joint between the inside of the coiled tubing and the CT tool string or another line of required coiled tubing. The joint O.D. is the same as the coiled tubing.
The tubing end must first be prepared by removing the inner bead using a CE Bead Removal Tool* and fully polished to make an optimum seal. The Roll-On Connector can then be inserted and the tubing roll formed over internal radii on the connector body using a DTI Roll-On Form Tool*. Although it is not the strongest or full bore, this is a useful, cost-effective, disposable connector that is quick and simple to attach. It is often used for wash tool string applications.
* Refer to CE Coiled Tubing Connector Preparation Tools below
CE CT PREPARATION TOOLS
– The Bead Removal Tool is a precision tool used to remove the weld bead from inside the coiled tubing so that the Roll-On CT Connector can be installed.
– The Tubing Honer is a universal tool used to polish out the inside of the coiled tubing to ensure an optimum seal when installing the Roll-On CT Connector.
– The Roll-On Form Tool is a universal tool used to roll the radius grooves onto the coiled tubing when installing a Roll-On CT Connector.
PUMP-OUT-CHOKE-PROBE
The CE CT Pump Out Choke Probe is run below the Hydraulic Knuckle Joint in the Multi-Lateral Entry System. The Pump Out Choke Probe is generally sized so that the Hydraulic Knuckle Joint is prevented from fully articulating inside the main wellbore casing. Once the lateral wellbore is located, the Pump Out Choke Probe moves into the casing window allowing the Hydraulic Knuckle Joint to fully articulate. This position opens the bleed ports and provides a pressure signal meaning that the lateral wellbore has been located.
A pinned piston sub acts as a choke to enable the activation of the hydraulic tool string. Once the lateral wellbore has been successfully accessed, the choke sub can be over-pressured and pumped out into the probe body which also acts as a catcher sub. Higher flow rates can then be pumped through the tool-string for any cleaning and stimulation applications.
FEATURES AND BENEFITS
- Available in all OD’s and lengths to suit main bore casing size options
- It features an adjustable pump-out pressure
- It features an adjustable choke size
- Available in all standard materials and thread connections
