132”RSC160, 9 HDPE Elbows and 1 Manhole




    Oregon, USA

After months of planning, environmental studies and construction, an ambitious project was to lay 3,020 feet of pipeline in a canal in southeast Bend, Oregon.

The project is part of a larger effort by the District to replace its open canals with pipes, a move the district says will conserve up to 50 percent of the water in the irrigation system from evaporation and seepage. At the height of the season, late summer, up to 150 cubic feet per second will flow through the pipe.

The most important aspect of a commodity-based irrigation system which sells water is to be able to ensure that there are no leaks in the system, otherwise there could be potential monetary loss. Weholite is able to address this simply by its robust material characteristics and fabrication method. During fabrication of a large diameter, double-walled pipe, a single beam is extruded and fused together using a unique heating method which allows two separate solid surfaces to become a single homogeneous piece rather than a normal weld, which is known to “hold” two surfaces together. This particular method allows a very minimal chance of leakage throughout the Weholite system.

Infra Pipe worked extensively with the Central Oregon Irrigation District to provide its Weholite offering for the impressive project at hand. The project called for 3020 feet of 132” RSC160 Weholite Large Diameter HDPE Pipe, 9 elbows, and 1 access chambers and several turn-outs. The installation of the Weholite pipe began in February of 2018 and concluded successfully in March of 2018. The joining of the pipe was completed by using the extrusion welding process where the joint is leak free and stronger than the pipe itself.
