CT Pressure Activated Firing System,
Percussion Initiator Bottom Load
Description
The Coiled Tubing Pressure Activated Firing Head was developed for use where pressure
firing is required such as in horizontal wells, well stimulation, or as a backup firing system.
This firing head utilizes our precision shear pin technology with an accuracy of ± 5%.
This system can be set to activate a predetermined pressure ranging from 2,000 to
18,000 psi in adjustable increments by using two sizes of precision shear pins.
Features and Benefits
• Can be used with the Owen Time Delay Fuses.
• Can be placed on top or bottom of all Owen Small Scalloped Gun Systems
(1-11/16”, 2-1/8”, 2-1/2”)
• Well suited for highly deviated wells
• Minimum operating pressure 2,000 psi (14 MPa)
• Maximum operating pressure **18,000 psi (124 MPa)
• Requires pinning to 8,000 psi (55 MPa) to pass API RP-67 drop testing
• No metal to metal contact between Firing Head and Percussion Initiator
• The top thread connection is specified when ordering
**Damage may occur when running the tool at these higher pressures

To install and tighten Retainer Nut you can use the Hex Socket (TC-033-0010000 sold separately). The tool is built so the tip of the wrench allen will not
contact the case of the detonator. Uses 3/8” drive.

Warning: The assembly of this tool requires the handling of an
Explosive Device and all safety precautions must be adhered to and
observed! Only personnel trained in explosive handling procedures
should be allowed to arm this assembly
Caution:
The shear pin values shown on the package
accompanying this tool are valid ONLY for the tools listed in this
manual
Caution:
Correct shear pin values will vary between lot dates,
always reference the data accompanying the pins!
Note: Check all items against the parts list to be sure of having the
correct parts and quantities.
Note: Check for any damage to the parts which would prevent the part
from being assembled correctly, easily and safely.
1.0 Assembly
1.1
Install the O-Ring (item 9 and 10) onto the Piston Housing (item 4). Set aside

1/27/16 1:47 PM

1.2
Install the O-Rings (item 7) on the Shear Piston (piston part of item 1). Apply one drop of Blue
Loctite® on the threads of the Firing Pin (item 12). Thread the firing pin into the shear piston
and tighten.
1.3
Slide the Outer Shear Ring (part of item #1) over the shear piston, matching the alignment
mark and numbers on the ring and piston. This will align the holes that were match drilled.
1.4
Install the O-Ring (item 8) on the groove of the Outer Shear Ring. With the tip of the shear
pin facing outward, insert the correct size and quantity of pins as per job requirements (refer
to the Pinning Procedures and Temp. Correction Chart in the back of the manual). Owen
recommends inserting the Shear Pins (items 2 and 3) as symmetrically as possible around
the outer shear ring. Starting with the large pins, first fill one (1) row before inserting pins in
the next rows.

1.5
After the correct number and size pins are inserted, you can apply a thin film of grease over
the pin tops and ring to help retain the pins during further assembly of this tool. Do not place
grease in holes of shear piston this makes it difficult removing the sheared off pin stubs from
piston. It is recommended installing the pins in a vertical position to prevent them from falling
out.
1.6
Apply grease to the O-rings on the shear piston (item 1) and the entry angle of the piston
housing (item 4). Insert the shear piston (item 1) into the housing until the outer ring is flush
with the edge of the housing. Again it’s best to do this in a vertical position and until the
Retainer Cap (item 5) can be threaded onto the piston housing. The cap is what retains the
pins during your operation. Install the O-Ring (item 11) on the top groove of the Outer Shear
Ring.
1.7
Apply light grease to the threads and O-ring of the piston housing (shear ring end) and thread
on the Retainer Cap (item 5). Remember, the retainer cap comes blanked out and must be
machine threaded to meet the particular thread requirements of the tubular to be used.

(These steps MUST be accomplished with NO DETONATOR in the detonator body.) Apply
grease to the threads and o-rings on the piston housing (item 4) and thread into the Detonator
Body (item 13) until both bodies are flush metal to metal. Tighten with no more than 150
lb-ft (203 Nm) of torque. Thread in the two Set Screws (item 15) into the upper end of the
detonator body and tighten.
Caution:
The next steps are only used prior to the well
operation. Never ship or attached an arm firing head with an
explosive component.
2.0 Detonator Installation
2.1
Remove the CP Detonator (item A) from its shipping package and install O-ring (item 6) into
the groove in the bottom of the CP detonator. Place the CP with o-ring into the Retainer Nut
(item 14). Install the CP-Rubber Washer (item 16) on top of the CP detonator and inside the
lip of the retainer nut.

2.2
Thread in the retainer nut (item 14) assembly with CP detonator into the detonator body until
the lip of the retainer nut makes contact with Internal surface of the detonator body (item 13).
Do not force retainer nut, if hard to thread, remove and check for cause. The retainer nut uses
a 3/8” Allen Wrench or the Hex Socket (TC-033-0010-000) to thread in. To secure, use no
more than 20 lb-ft (27 Nm) of torque. A torque wrench is reccommended.
Note: To secure the retainer nut, use no more than 20 lb-ft (27 Nm)
2.3
of torque. A torque wrench is reccommended. Caution: DO NOT use any
pointed device to install the Retainer Nut Assembly into the detonator
Body as it may cause detonation and serious injury.
Install the Top Sub Rubber Washer (item 17) inside the detonator body and up against the
retainer nut. This washer is used to prevent the retainer nut from backing off and as a debris
barrier.

must be used when handling and installing it on the main well
device! REMEMBER you are handling explosive components so
handle safely and do not over tighten any connections.
