PVC-U Corrugated Twin-wall Pipe
Corrugated (rib-enforced) twin-wall sewage pipes are made of un-softened polyvinyl chloride ( PVC-U ) and are intended for the discharge of precipitation and industrial waste waters, drainage ,low-pressure and gravity water. Owing to its high quality, PVC is resistant to mechanical impacts, abrasion and negative chemical impact of acids, alkalis, salt compounds, bases, sulphates, alcohol and many other chemicals. The pipes are fully compliant with the quality standards stipulated by ISO 21138 :2007 The pipes with double walls and outer-rib enforcement are up to 40% lighter than pipes used to the same purposes (depending on the diameter). They are highly durable and resistant to mechanical movements of the ground. They are also very good electrical insulator and are easily installed. In addition to their long service life, they pose very few maintenance requirements. The connections are made using a socket fitting (collar) and a rubber ring, securing full tightness of joints. Corrugated PVC pipes and the corresponding PVC accessory parts can be permanently applied within the temperature range between 0ºC and +60ºC. Corrugated PVC pipes are produced to standard parameters of perimeter rigidity of SN4 (4kN/m²) i SN8 (8kN/m²), while higher values of perimeter rigidity of up to SN 16 are made to order, for non-standard projects. The outer pipe diameters are in the range from DN 160 to DN 500 mm, and the standard pipe length is 6m. Other lengths are supplied to customer’s order.
