PVC-A PN8 Water Pressure Pipe D110-500mm

The LaReTer PVC-A PN8 piping system is an advanced thermoplastic alloy engineered for pressurized water distribution, industrial utilities, and agricultural irrigation networks. Manufactured by Lareter Spa in Italy, this polymer alloy combines the high tensile strength and rigidity of PVC-U with the ductility and impact absorption of chlorinated polyethylene. This compound eliminates the ductile-to-brittle transition risk, preventing rapid crack propagation caused by concentrated external loads or surface scratches. PVC-A is approximately 25 percent lighter than standard polyethylene pipes of equivalent pressure class, optimizing handling and transport efficiency.

Each pipe is produced in a 6-meter standard length with an integrated bell socket featuring the factory-fitted Forsheda Power-Lock sealing system. The joint incorporates an EPDM elastomeric gasket conforming to UNI EN 681-1, reinforced with a yellow polypropylene stiffening ring without metal parts. This design eliminates gasket displacement during spigot insertion and permits angular deflections of up to 3 degrees. The system maintains negative pressure tightness down to -0.5 bar and has a design life exceeding 50 years.
