Uponor Ultra Rib 2 Blue® is a gravity sewer system partially based on renewable plastic raw material. The pipes are used as sewer and storm water pipes in various kinds of applications like municipal, transport, commercial and residential. Ultra Rib 2 Blue® is a ribbed and massive non-pressure pipe with injection moulded in-line socket. The material is polypropylene. Pipes are available from outer diameter 200mm up to diameter 560mm. Outer layer of the pipe is red brown and inner layer is white for easier inspection. The pipe has an injection moulded in-line socket, which is a solid part of the pipe and is produced on extrusion production line. The in-line socket reduces the number of joints needed by 50%. Ultra Rib 2 Blue® pipes uses renewable PP raw material for the pipe is based on the Bornewables™ product range supplied by Borealis. These raw materials are made using sustainably sourced renewable feedstocks derived solely from waste and residue vegetable oils, such as used cooking oil and residues from vegetable oil processing. The residue from vegetable oil processing consists of rancid fat that has to be removed to produce food-grade oil. The used cooking oil, entirely waste and residues in origin, is a waste stream collected from restaurants and the food industry. The waste and residue raw materials that are used to produce our feedstock are no longer fit for human consumption, and as such, do not impact food security. Ultra Rib 2 Blue® pipes are extremely tight, safe and strong. Socket has perfect shape and tolerances. Pipe cavity can be filled well-graded soil with up to 60mm particle size.
