Two-layer polyethylene corrugated pipes TW-CORR, SN4 and SN8, for external sewerage and drainage

Two-layer corrugated pipes TW-CORR made of polyethylene (PE) for external non-pressure industrial, domestic, fecal and storm sewers.

Diameters - 110mm, 160mm, 200mm, 250mm, 300mm, 400mm;

Hardness class - d160-400mm SN4, d 110-400mm - SN8;

Material - HDPE polyethylene;

Depth of SN4 pipes - up to 5m, SN8 - up to 10m.

 

The TW-CORR pipe is an analogue of the two-layer corrugated pipes KORSIS, but is supplied immediately with a coupling and a seal.

 TW-CORR pipes are used for outdoor non-pressure domestic and storm sewer networks, as well as for drainage. Double-layer corrugated pipes, due to their high ring stiffness (SN8 and SN4), can be used as a protective case when laying pressure pipelines under roads and railway lines.
