The product is made of HDPE (high density polyethylene). These double walled pipes with smooth inside and helical web on the outside are characterized by properties such as high loading capacity – ring stiffness SN 8- great elasticity, low weight and insensitiveness to out-side influences.
The unique structure of Pecor Optima® pipes is a result of Scandinavian long-term experience in culvert & sewage technology. The corrugation is stiff and can interact with surrounded soil. The corrugation size and the distance between corrugation depend on the diameter of the pipe.
HDPE pipes are assigned to the principle of flexible, embedded pipes. The pipes supplied in great single length are connected with sockets or so called coupling bands. With appropriate and professional backfilling these pipes can bear high loads even with low height of fill.
