HIGH PRESSURE FILTER-SLEEVE
High Pressure Filter-Sleeve™ is an internal repair method, designed for rehabilitation of well casings, designed for differential pressure up to 50 psi . Repairs holes, cracks and corrosion damage.
Advantages:
- Compared with resin-sealed repair sleeves, dry Filter-Sleeve™ has several advantages:
- No time pressure for resin handling
- No wait for resin to cure
- The process is clean and dry and allows good control over handling and installation
- Fast application … 20 minutes to 1.5 hours depending on local conditions: Accessibility, Depth, etc.
- Fast return to service
LOW PRESSURE SLEEVE
Low Pressure Sleeve™ is an internal repair method, designed for rehabilitation of water mains and water wells with differential pressure up to 5 psi. All product components have individual NSF or FDA approval.
Once the sleeve is brought into repair position monitored by the CCTV camera, the air/hydraulic pressure is introduced and the sleeve is expanded. When full installation pressure is reached the sleeve locks itself in place and the resin behind the sleeve starts curing. Air pressure is then released immediately and equipment is retrieved. There is no need to hold the pressure inside the sleeve while resin is curing, since the sleeve is designed as a self-curing repair device.
