UV curing systems and equipment for trenchless sewer rehabilitation: Perfectly matched to the needs of Alphaliner

The success of a UV GRP pipe liner rehabilitation project depends greatly on the technologies used. With our Alphaliner, RELINE is the global leader in the field of trenchless pipeline rehabilitation with UV light curing. As the only manufacturer of GRP pipe liners, RELINE also develops and produces complete systems and equipment, from UV curing systems to complete turnkey conversion of rehabilitation and service vehicles. And all RELINE AMERICA materials and equipment are manufactured right here in the United States, so there’s no unnecessary wait for delivery or support.

WHAT IS GRP TECHNOLOGY

Glass fiber-reinforced plastic (GRP) is one of the most versatile materials that can be designed and used successfully in numerous industries such as the aircraft, automotive, shipbuilding and wind turbine industries.

As a high quality, fiber-reinforced composite (FRP), GRP is produced by combining several materials: the molding matrix, such as polyester, vinylester or epoxy resin; and reinforced high-strength fibers, usually glass, aramid or carbon.

With GRP technology, RELINE offers an optimal GRP pipe liner for trenchless pipeline rehabilitation that is tailored to the static requirements of the sewer, the characteristics of the wastewater or other media, and each installation’s given safety requirements.

Materials of the highest quality—special ECR glass fiber and a resin adapted to UV light curing—form the basis for this successful GRP technology. Our exclusive process enables optimal curing with innovative UV light curing, for long-lasting quality and performance of the end product.

WHAT IS UV TECHNOLOGY

UV technology is the use of ultraviolet light to cure and harden resins. This technology is used in many fields, but in trenchless pipeline rehabilitation, it was developed to create a faster, safer, more trouble-free process.

  • Faster, cleaner, more flexible to schedule – Requires no on-site wet-out process to impregnate resins into liner material, eliminating the need for tight scheduling and long prep hours on the construction site.
  • No on-site wet-out reduces the chance for foreign objects to contaminate the resins and possibly interfere with effective curing and performance.
  • Eliminates toxic off-gassing of older steam-cure technology, making it safer for installers, neighbors and the environment

UV curing systems from RELINE are characterized by constant, maximal performance, the fastest curing times, and the best possible control and documentation.
