CIPP Lining

CIPP Lining Cured in Place pipe (CIPP) can be used to rehabilitate sanitary sewers, storm drains and pressure pipelines for water, gas and process effluents. Circular pipes from 80-2000mm and a variety of noncircular pipes such as egg shapes, ovoids, and box culverts can be lined.

The cured liner inside the old pipe will actually perform as a new jointless pipe.

Water penetrating the sewage line through holes, cracks, and common damages may significantly impair the operation process, especially in the event of heavy rain and storms. Helios CIPP technologies can dramatically reduce water infiltrations and finally remove all leaks from the system. In hot and dry environments, trees and plant roots reach down into the sewer line where they can find water and nutrients. Hydraulic and structural problems occur at the areas where the roots enter an existing pipeline.

Helios CIPP technologies are designed to stop flow leakage out of the pipeline, and prevent water and roots from penetrating the pipe at the same time. With us, you will save on social costs for expanding your existing purification plants, and also remove the environmental problems caused by the sewer hydraulic failures. Helios CIPPs allow the restoration of the structural integrity of damaged sewer lines. Our design models, many independent tests, and over 40 operation                years provide exhaustive evidence that CIPP structural methods yield an average life time of at least 50 years.

Helios systems include flexible methods and a vast range of materials. Helios CIPPs can be either pulled or inverted inside the pipe using air or water. Curing can be carried out with UV, steam, or hot water. All processes are compliant with the reference National standards and quality ISO-certified. We are in a position to design our system tailored to your job specifications so that we can bring the most viable and optimal solution to your rehabilitation needs.

CIPP liners of non-woven polyester felt or fibre reinforced fabric are manufactured to fit the host pipe. The liners are impregnated with a polymer resin, which will form a close fitting liner pipe within the host pipe when cured. The liner may be designed with sufficient cured thickness to sustain the loads imposed by the external groundwater and internal service pressure, as well as by soil and surface traffic.

The liner is impregnated with polyester, vinyl ester epoxy or silicate resin using vacuum, gravity or other pressure systems. The resin includes a chemical catalyst or hardener to facilitate curing. The outermost layer of the liner tube is coated with a polymer film to protect the liner during handling and installation. The impregnated liner may be chilled for transportation to maintain stability until installed.

The impregnated liner may cure at ambient temperature, although most common curing methods normally utilize  heat  from the recirculation of the inversion water through a boiler, blending steam with inflation air or by pulling a UV light train through the pipe. When the pipe has cured, the liner is cooled and the ends removed flush with the pipe ends, and sealed if necessary. The curing water, or steam condensate and the liner cutoffs are removed for safe disposal. A sample of the CIPP may be taken from the pipe ends or from a mould cured under the same conditions and used for testing and quality assessment purposes.
