Weholite sopii vesistöasennuksiin: se kestää suolavettä ja korroosiota, hitsausliitokset ovat vesitiiviitä ja toimitusvalikoima ulottuu DN/ID 3 500 mm saakka.

Cooling intake and outfall pipes

Durable pipes for underwater installations

The installation of intake and discharge pipes in water is a multi-stage project, which includes pressure and strength calculations, material deliveries, welding, assembly, and execution of the actual installation. Uponor can supply all the relevant services as a complete package.

Weholite is suitable for installation in water; it withstands salt water and corrosion, the welding joints are waterproof, and the available size range reaches up to DN/ID 3,500 mm. The light pipes are easy to install and handle, even for the larger diameters. Flexible pipes adapt better to the load variations of ground water than rigid pipes do.

Conventional polyethylene pipes with solid walls are typically weighted against buoyancy with external concrete weights. This approach can also be used for Weholite pipes, but it is preferable to make use of the pipe's flexible structure by filling the hollow thread profile with concrete mortar. This method saves you dredging costs, since the trench needed for a profile weighted pipe is narrower than the one required for outside weighting. Profile weighting is not only quick, it requires less heavy installation equipment, and any related welding can take place at a separate work site. Plumbing components can be towed to the final installation site with pontoons.
