Trident-Seal® Live Natural Gas Repair Kit
Permanently Seals Active Leaks up to 60 psi. Designed and Tested for Natural Gas Industry.
PRODUCT INFORMATION
Trident-Seal®, live natural gas repair system permanently seals active leaks, up to 60 psi (4 bar) without interruption to service. These kits are pre-packaged for up to 6 inch diameter, larger repairs can be made by utilizing more than one kit. Each kit contains enough material to repair pinholes or threaded fittings.
Third party testing for long term pressure retention has been conducted at 90 psi (4 bar). The Trident family of products was specifically designed for the natural gas industry and requires Operator Qualified training.

PREPARATION & APPLICATION
-
1
Locate origin of leak following standard leak detection procedures. Reduce line pressure to a max of 60 psi (4 bar).
-
2
Roughen pipe surface using wire brush and supplied sanding cloth to remove excess rust, dirt or loose scale. Remove any oils, greases, soaps or foreign materials from pipe surface by utilizing the included solvent cleaning wipe.
-
3
Unroll first 6" Unroll first 6” (15cm) from roll of black rubber Pressure Sealing Tape (PTR) and remove backings. Set aside. Remove Trident-Seal Putty from packaging and knead until uniform in color. Maximum mixing time: 3 minutes. Minimum mixing temp: 50ºF (10ºC)
-
COMPLETE #4 OR #5 DEPENDING ON YOUR APPLICATION, THEN PROCEED TO #6
-
4
JOINT: PINHOLE: Place a ball of mixed Trident-Seal Putty which is large enough to fill the void above pinhole.
-
5
THREADED FITTING: Mold mixed Trident-Seal Putty into a 1/8”-1/4” (3mm-6mm) rope and place around entire circumference of the joint, pressing firmly into place. NOTE: the rope should not exceed the shoulder of female fitting.
-
6
Wrap the black rubber Pressure Sealing Tape (PTR) in overlapping manner in a clockwise direction, working toward putty, pushing it downward into the defect, stretching the PTR to its maximum tension while wrapping DIRECTLY over the putty. This will force the putty firmly into place. DO NOT CHASE THE LEAK, as each wrap provides additional pressure to seal the leak. Use entire roll.
-
7
STOP! After applying the PTR, test repair by following your leak detection procedures to ensure the gas leakage is sealed and contained. If leak persists, remove PTR and putty and repeat steps 1-7.
-
8
Water is needed to activate the Trident-Glass Outer Wrap. Put on supplied gloves, open foil pouch and submerge the roll of Trident-Glass in water for 10 seconds. 8 layers of Trident-Glass Outer Wrap are required and must extend 2” (5cm) on either side of the PTR, covering the entire repair site. NOTE: To achieve an 8 layer application, apply 4 passes in a clockwise direction using a 50% overlap. Occasionally twisting the Trident-Glass as it is applied helps it conform tightly to the pipe surface.
-
9
Apply 4 layers of clear plastic compression film over the entire composite repair, wrapping in the same direction as the Trident-Glass was applied. Using a perforating tool or wire brush, perforate all layers of compression film to allow the gas generated by the curing process to escape. Remove compression film after 10 minutes.
-
10
Once the Trident-Glass Outer Wrap has reached its initial cure, 28 minutes @ 75ºF (24ºC), it should be protected with a UV coating, such as Syntho-Glass®UV before returning to service.
