Designed for active leaks with a pressure boundary up to 100 psi, the LeakStop™ system is a mechanical clamping solution consisting of a sized Fiber Reinforced Plastic (FRP) shell lined with a gasket and secured by metallic compression bands. The LeakStop™ system is available with gaskets not only for standard service, but also for chemical service applications. The system provides complete fit-up integrity between the sealing gasket pad and the pipe, creating a compression seal to stop the leak. Temperature-rated to 250° F, the system installs quickly with minimal down time.

Installation Procedure

1. Position and Secure LeakStop™ Pad

1_7Thumb

Position the LeakStop™ pad over the defect. Secure the stainless steel banding clamp over the pad center and tighten the band until the leak stops.

2. Position and Secure Remaining Bands

2_8Thumb

Position and tighten each band using the tensioning tool. Media blast or grind the remaining repair area to create a clean anchor patter, then solvent wipe the surface.

3. Apply Load Transfer Putty to Band Clamps

3_4Thumb

Knead putty until uniform in color. Then apply the putty to the band clips using a “tented profile.”

4. Apply Epoxy Paste

4_4Thumb

Mix and apply a 30 mil coating of epoxy paste. Allow the paste to thicken for 10-15 minutes – a “peanut butter” consistency is desired.

5. Apply Pipe Wrap® and Topcoat

5_2Thumb

Apply provided PipeWrap® using the cigar wrap method. A topcoat may be applied after two hours.
