Alvehol 1200 is a PVC pipe intended to be used for non-pressure underground drainage and sewerage systems with perfectly smooth internal and external surfaces.The pipe wall is not compact but consists in a sort of cells in the longitudinal direction. The wall structure can be regarded as a double T beam; this configuration gives equal mechanical properties but lower weight compared to a compact PVC pipe. Sirci Gresintex has developed an extrusion line for Alvehol pipe nominal diameter up to 1200 mm, with formulations containing new generation of stabilisers (“lead free”). Other advantages of Alvehol in the production process, are the lower material consumption in comparison with the same diameter pipe and mechanical properties, the easier handling during installation in difficult situations and the choice of non-toxic formulations.
