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).

Free-flow system GOFR

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

110 110 90
160 160 135
200 229 198

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.

 

2. Cable protection system GOFR-E

Cable protection system GOFR-E

Dnom, mm Dnar, mm Dvn, mm
110 110 90
160 160 135
200 229 198
250*

Corrugated pipe GOFR-E is an excellent protection against mechanical damage or electrical fire, television and telephone cables, voltage up to 10 kVolt. The pipe is made of HDPE outer diameter 110 and 160 mm, in lengths of 4 or 6 meters. Tubes with a diameter of 110 mm can be supplied in coils of 50 lm

Pipe GOFR-E is simple to install, easy and convenient to transport, which reduces the cost for transportation, in addition, it is an insulator, and does not require grounding.

Warranty service life Pipe GOFR-E is 50 years.

 

3. Cable protection system GOFR-D

Drainage corrugated pipes used in the creation of drainage systems to protect buildings or portion of the excess moisture, the seasonal rise of water table. Drainage is a complex system of interconnected tubes arranged around or along the perimeter of the water structures. The system comes running down to the ground water.

The pipe can be perforated on the walls, and fitted a filter geotextile.

Drainage Corrugated pipe GOFR-D is manufactured from HDPE outer diameter 110 and 160 mm, in lengths of 4 or 6 meters, complete with dvuhrastrubnoy clutch and two sealing rings.

 

For various tasks factory «Spiroplast» offers four types of pipes series GOFR-D:

GOFR-D - without perforations

GOFR-D – without perforations. Infiltrovanyh used to transport wastewater to the wells
