PVC

PVC - Polyvinyl chloride - is a RAL 7011 grey color thermoplastic unable to resist UV rays, so it is not suggested for above ground installations without suitable protection against sun rays. If this aspect is not considered, the material starts aging and the component becomes more fragile.

PVC complies with the requirements of Directive 90/128/EEC and is physiologically usable with food products.

The fire resistance rating is B1 according to DIN 4102 standard and V-0 according to UL 94 standard, so this material is classified as self-extinguishing.

The Hürner Italia S.r.l. program offers a wide and extensive liquid conveyance line with sizes from OD 10 mm to OD 400 mm with NP 2.5 - 4 - 6 - 10 and 16 bar, according to the diameter.

Pipes and fittings follow UNI EN 1452 standard, while valves refer to UNI EN ISO 16135 for ball valves, UNI EN ISO 16136 for butterfly valves, UNI EN ISO 16137 for check valves, and UNI EN ISO 16138 for diaphragm valves.

The procedure and check of chemical gluing is defined in UNI 11242 standard - PVC-U, PVC-C and ABS joints for the conveyance of fluids under pressure and not under pressure.
