Are you looking for the curing method using UV light or hot water and steam?
Rehabilitation of open channel pipelines
The service life of wastewater pipes is inherently limited. For this reason, lining methods were developed decades ago to eliminate the need to dig up and replace pipes. Pipelining has continued to evolve and is now common practice in many European, American, and Asian markets. A distinction is made between different types of liners and curing methods. Depending on the application and conditions at the construction site, different systems and methods are used to achieve the optimum result at the construction site. IBG HydroTech offers a wide range of innovative systems for trenchless pipe rehabilitation.
Our UV curing systems were developed in Germany and are manufactured by skilled personnel in Alzenau in Lower Franconia. By purchasing a vehicle with an integrated UV system for curing glass liners, our customers have full freedom of design. The touch panel on the system makes operation simple and timesaving. The light chains in various sizes, which have been specially developed for curing with UV light, can be coupled to an existing system as required. Therefore, a single-vehicle extension can be equipped for dimensions from DN 150 – DN 2.000, thus ensuring the greatest freedom in order processing for service providers in the pipe rehabilitation sector.
Curing of felt liners in bendable pipes
For the curing of felt liners in bendable pipes, hot water or steam curing is used. The pipeliner can be easily and quickly inserted into the pipe to be rehabilitated with the help of the inversion drum. Rolled in, it is “inverted” into the pipe from inside the drum through air. The resin-impregnated fabric lies on the outside of the inner pipe wall, while the coated inner protective film lies on the inside of the liner. The inversion pressure and speed can be adjusted via the control on the drum. After the liner has been inverted, the heating medium (water or steam) is introduced via the drum so that the resin cures and a new pipe is formed in the old one.
