Free-flow system GOFR is a double-wall corrugated pipe, made of modern polymers. Plant «Spiroplast» produces three types of pipes GOFR: GOFR-K (gravity drainage), GOFR-E (cable protection system), GOFR-D (drainage).
These systems can be used for construction of networks of external sewage, drainage, as well as a protective cover for laying electrical, telephone and cable television.
Pipes and fittings are made to them in accordance with DSTU BV.2.5-32: 2007 and EN 13476-1:2002 European requirements and EN DIN4261-1:1998-12.
Plant «Spiroplast» makes systems GOFR three types:
1. The sewer system GOFR-K

Corrugated pipe for gravity sewer outside GOFR-to made of polyethylene pipe grades. In the case of wastewater containing corrosive environments and high temperature environments, systems GOFR-K are made of polypropylene.
For the construction of non-pressure sewerage outside plant «Spiroplast» makes GOFR-pipe to a diameter of 110, 160 and 200 mm with ring stiffness SN4 and SN8. The pipes are made with bells, lengths of 6 m, or 12 m lengths complete with dvuhrastrubnoy clutch and two sealing rings.
