Product Description

COILED TUBING TOOLS

DUAL FLAPPER CHECK VALVE
The Dual Flapper Check Valve is used in situations where the operator wishes to eliminate the flow or potential flow of fluids back through the work string while running or retrieving pipe under pressure.
The Dual Flapper Check Valve is designed so that the flow area through the valve is equal to or greater than the cross sectional area of I.D. of the valve seat. The Dual Flapper Check Valves are easy to assemble or disassemble, a new flapper cartridge can be inserted in a matter of minutes. The Dual Flapper Check Valve combines reliability, minimum flow restrictions, and the ability to pump wiper plugs or to drop balls through the valve for disconnects, etc.
As with ball type check valves, rust, scale, paraffin, dried hydrocarbons or materials do not pose a threat of plugging this flapper check valve due to the ability to pump through the valve at all times.
The flapper valve and seat are directly exposed to the pumped fluid and some errosion may occur on the seat surface and possibly the flapper valve itself, depending on a variety of factors including velocity through the valve, abrasiveness of the fluid pumped, solids content, and duration of the exposure. The flappers and valve seats should be checked and replaced when required

TWIN FLAPPER CHECK VALVE WITH LOCK-OUT SLEEVE
The Twin Flapper Check Valve with Lock-Out Sleeve is a coiled tubing string component that can be run in the locked out position and activated with a drop ball when required to perform as a downhole safety barrier. Its use provides a means of preventing the back flow of well fluids into the coiled tubing in the event of failure or damage to the coiled tubing string or surface equipment.
The design of the Twin Flapper Check Valve incorporates a dual sealing system in each flapper assembly for increased safety. A tefn seat provides the primary low pressure seal, while at higher pressure the flapper seals on a metal to metal arrangement.
It is ideally suited to CT velocity string systems allowing activation by a drop ball prior to pulling the string from the well.
Design Features/Benefits:

• Dual sealing in each flapper cartridge i.e. low pressure Tefn seat/seal and high pressure full metal to metal seat/seal
• Full bore fluid passage for balls, darts & plugs
• Removable flapper cartridges
• Simple drop ball activation

BALL CHECK VALVE
The Ball Check Valve is a standard coiled tubing string component. Its use in a tool string provides a means of preventing the back flow of fluids into the coiled tubing in the event of failure or damage to the surface equipment.
Ball Check Valves are used when devices such as balls and darts do not need to pass through the valve. In the event of a ball or dart needing to be dropped a Flapper Valve must be used.
Design Features/Benefits:

• Large flow area
• Easy redress
• Metal to metal sealing

HEAVY DUTY HYDRAULIC DISCONNECT

The Heavy Duty Hydraulic Disconnect (HDHD) allows the tool string to detach at a predetermined point via the deployment of a suitable drop/trip ball through the coiled tubing. The drop ball locates on a piston sleeve creating sufficient back pressure to shear the pins and disconnect the tool. The piston sleeve pushes the tool apart to ensure a clean disconnect. Circulation is immediately returned to the tool string, providing a surface indication of a positive disconnect. All piston sleeves and drop balls are returned to surface leaving a standard 'GS' internal fish neck for retrieval purposes.
The 'HDHD' utilizes a heavy duty, one piece, threaded collet slip to hold the tool together. The collet slip endures higher tensile loading than collet finger type release mechanisms and is far less susceptible to fatigue. The collet slip is backed up with a collet slip sleeve to give maximum tensile strength to the disconnect during heavy jarring operations. Only by dropping a ball and shearing the pins can the collet sleeve shift, allowing the collet and top sub to part. The piston sleeve is pressure balanced, therefore internal pressure does not affect the hydraulic configuration and shear values.
High torque capabilities are achieved through positive torque drive teeth between the top sub and the main body of the tool. The 'HDHD' is therefore ideally suited for high torque, heavy duty coiled tubing drilling operations where maximum performance and durability is essential.
Shear screws can be supplied in either brass or steel to give a comprehensive pressure range to suit virtually any coiled tubing application. Shear screws are also integrally situated to eliminate the possibility of shear screws vibrating free during CT drilling operations.
By interchanging the piston sleeve, the drop/trip ball size can be varied to suit the desired tool string requirements. This is a particularly useful feature when the 'HDHD' is situated below jars and accelerators, and ID restrictions are a factor for consideration. Running the 'HDHD' below jars and accelerators ensures that if disconnection of the tool string is necessary, a greater proportion of the tool string is safely returned to surface.
A major design consideration is that of simple field redress. The 'HDHD' has been designed to ensure assembly & disassembly of the tool is trouble free. No special assembly tools are required and all seals are standard 'o' rings.

DUAL ACTIVATED CIRCULATION VALVE( DROP VALL/OVER PRESSURE)
The Dual Activated Circulation Valve offers the traditional method of returning circulation of the tool string through use of a drop ball. In addition, the valve is capable of operating through internal overpressure within the tubing string.
Conventional dual circulation valves use a burst or rupture disc to facilitate the function of returning circulation through overpressure. However, the Dual Activated Circulation Valve offers a pressure differential activated piston. The piston activation pressure can be predetermined at surface through shear pins, offering superior flexibility and considerable savings on redress.
As with many other tools in the standard BHA tool range, the emphasis is on simplicity and the Dual Activated Circulation Valve has very few component parts, seals and thread connections.
Design Features/Benefits:
-Simple drop ball design and pressure differential to operate

BURST DISC CIRCULATION SUB
The Burst Disc Circulation Sub is a standard coiled tubing tool string component that is used in conjunction with tools that require drop balls etc., and that need to be circulated into the coiled tubing.
The Burst Disc Circulation Sub is incorporated into the coiled tubing tool string just below the tool that requires a drop ball.
Should circulation be lost due to a down hole restriction, a predetermined pressure applied to the coil will burst the disc in the sub and re-establish circulation.
Design Features/Benefits: Various burst disc pressure rating available

STRAIGHT BAR

The Straight Bar provides a means of extending the tool string, while maintaining the maximum through bore. The tubular section between the top & bottom sub can be interchanged to vary the length of the straight bar. This approach offers an ideal way of spacing out tools within the tool string, without compromising the flow requirements of flow activated or jetting tools.

DOWN STROKE INTENSIFIER
Its purpose is to provide the necessary even pull and acceleration power for the Coiled Tubing Down-Stroke Hydraulic Jar to operate efficiently, especially in long reach wells where there is limited coiled tubing push.
The Coiled Tubing Down-Stroke Intensifier stores downward energy in a powerful compression spring, which is suddenly released when the Hydraulic Jar 'releases', thus intensifying the downward jarring impact.
The Down-Stroke Intensifier is fully vented to the well bore to prevent damping effect and has full 'pump through' capability, compatible with the PCE Coiled Tubing Hydraulic Jar
The Down-Stroke Intensifier is manufactured from high grade low alloy steel and stainless steel and is extremely robust and durable in construction.
Under normal conditions the Down-Stroke Intensifier will function at temperatures of up to 200°C if circulation is maintained during operations.
Design Features/Benefits:

• Full flow through bore
