Cured in Place Pipe Services
Cured-in-place-pipe (CIPP) is a trenchless pipe rehabilitation method for repairing broken, leaking, cracked, or corroded pipes. CIPP technology is used to restore water, sewer, gas, or chemical piping systems without the costly expense and disruption of surface activity.
The need for cured in place pipe installation is due to the fact that pipe corrosion occurs in virtually all types of piping systems beginning from the moment they are put into service. Corrosion build-up in piping obstructs water flow, collects lead and other potentially harmful elements, and results in the gradual deterioration of the pipe. EA Services Inc. cured in place pipe lining renews aging and deteriorated pipes, extending the life of your pipeline system.
Cured in Place Pipe Installation
Cured in place pipe (CIPP) is a jointless, seamless, pipe-within-a-pipe with the capability to rehabilitate pipes ranging in diameter from 6"-110". EA Services Inc. CIPP process consists of a pre-inspection of the pipe, after which an epoxy resin-saturated liner is inverted or pulled into the damaged pipe through a manhole or other existing access point. The resin is uniformly distributed on the entire pipe surface to create a pipe with a uniform wall thickness.
CIPP liners are versatile, being able to accommodate non-circular sections, bends, and changes of cross-section. They work for pipes constructed of all types of materials and for various loading conditions. The CIPP lining has a smooth internal surface, resulting in low hydraulic roughness.
The CIPP process does not require excavation for pipe rehabilitation. With little to no digging involved, our cured in place pipe services provide a more environmentally friendly method than standard "dig and replace" pipe rehabilitation methods.
EA Services Inc. uses inversion equipment specially designed to create a pipe-within-a-pipe solution.
The epoxy impregnated felt liner is vacuumed with special equipment to remove any excess material. This process is imperative in producing a perfect interior surface.
Curing the Pipe Lining
After the epoxy resin is in place, the resin-impregnated liner is cured either with heat or by ambient curing to form a tight-fitting, jointless, and corrosion-resistant replacement pipe out of the cured in place pipe liner. Ambient curing relies on the ambient temperature of the liner location to cure the new resin-impregnated pipe lining. A heated curing process, using hot water or steam, can be used to speed the curing process. The chemical reaction of the resin during the curing process results in a hard plastic material that provides strength and density for the pipe.
After the pipe lining has been completely cured, the ends are cut. Service laterals are internally restored with robotically controlled cutting devices. Closed-circuit television (CCTV) is used to inspect the rehabilitated pipe. The result of the CIPP services is a new pipe-within-a-pipe, all without costly excavation.
CIPP Materials and Equipment
EA Services Inc. has a wide variety of resident liner for all conditions. For offset joints, frequent sharp bends up to 90 degrees, and open ends, we have custom provided liners. For relatively straight sections or manhole-to-manhole, we recommend our liner tube. All of our cured in place pipe liners consist of the finest materials, and our cured in place pipe process uses the highest engineered equipment available.
Benefits of Cured-in-Place-Pipe (CIPP)
Cured in place pipe services provide cost-effective pipe rehabilitation for aging and deteriorating pipe systems without costly excavations. The cured in place pipe liner has quantifiable structural strength and can be designed to suit various loading conditions for water, sewer, gas, or chemical piping systems. With CIPP technology, you can restore pipeline integrity and extend the service life of your pipe.
