Emergency Repair
Definition - What does Emergency Repair mean?
Trenchless emergency repairs have two major characteristics:
They are usually associated with power plant and water treatment plants, or commercial facilities with similar piping systems.
Repairs are made by relining the affected pipes with fiber-reinforced polymer (FRP) linings that are flexible, like conventional lining tubes, and one side is coated with an adhesive resin. But unlike the linings used in smaller relining projects, the lining material is moved into the pipe and, when fully cured, becomes a structural element in the pipe.
Trenchlesspedia explains Emergency Repair
The liner is available in almost any length and diameter. It's lightweight, impermeable and has minimal -- if any --impact on flow rates. One side of the FRP liner is coated with an adhesive resin. When the FRP lining is applied to the pipe's surface in the same way wallpaper is applied to a wall (according to Mo Ehsani writing in Trenchless Technology Magazine) and when the resin cures fully, it forms a barrier that reduces the interior diameter of the pipe to less than 1.3 mm (0.5 in).
