For standalone point repair, or for pre-lining under high infiltration, the new Quick-Lock sleeve offers a rapid, easy-to-install and economical way to repair failing pipe. It restores the host pipe’s strength with heavy-gauge 316L stainless steel, and seals out infiltration with a single-piece vulcanized EPDM rubber gasket. Suitable for sewer, water and industrial applications, a Quick-Lock sleeve installs in minutes with minimal equipment and overhead.
“In the world of pipe rehab, performing localized repairs can still be a big undertaking,” says Sean Lipscomb, Field Operations Manager at Pipeline Renewal Technologies. “Either you’re digging up a road, or your using a trenchless method and everything that entails: resin mixing, winching, bypass pumping/plugging, wash-out risk, short pot life and long ambient cure times. Quick-Lock solves all these problems.”
Quick-Lock is positioned inside the host pipe on a wheeled flow-through packer pushed by any standard CCTV crawler. Once in position, air pressure supplied to the packer expands the sleeve against the pipe wall. Patented stainless gear ratchets within the sleeve sustain the outward pressure, which structurally reinforces failing regions of the host pipe, and also compresses the gasket for leak-proof service.
“The technology is as simple as it is effective,” says Lipscomb. “For small-diameter repairs, two people can install a Quick-Lock in about 30 minutes, and the only major equipment needed is a common inspection crawler. That repair will typically be comparable or superior to point repairs made using other trenchless methods.”
Quick-Lock sleeves address a variety of common pipe problems: infiltration, longitudinal and circumferential cracks, root intrusion, holes, leaks, offset joints and abandoned laterals. Quick-Lock sleeves are available in diameters ranging 6–28”, and in lengths of 16” and 20”. Multiple sleeves can be interleaved to perform longer repairs. The sleeve design meets ASTM F3110-14 for mechanical trenchless point repair.
“Quick-Lock is simply a much nimbler way to do point repair,” concludes Lipscomb. “The investment is minimal; the materials costs are extremely competitive; and the overhead—in terms of equipment, people and time—is remarkably low. It opens the door for anyone to perform point repair, from nationwide rehab contractors to small municipalities.”
