Alvehol 1200

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.

PVC-O pressure pipes for conveyance potable water irrigation and industrial uses

The project involves the production of PVC-O pressure pipes for conveyance drinkable water, irrigation and industrial uses. The process was made possible thanks to the phenomenon of biaxial molecular orientation during the production of rigid PVC pipes. In this way the molecular chains of PVC and their layout change from random to well organized type compared to a laminated. The process of molecular orientation developed by Molecor and licensed to Sirci Gresintex ensures high productivity and repeatability thanks tocontrol temperature, pressure and strain rate during molecular orientation. In this manner PVC pressure pipes improve the mechanical property and become a serious candidate for conveyance of pressurized fluids compared to other plastics pipes. The main advantages about using PVC-O pipes are: resistance to internal pressure, resistance to impact and accidental cuts, hydraulic performance, high flexibility, easy installation, energy efficiency.
