The PVC-U range is a system of products complete of: fittings for solvent welding, threaded connection and manual or automatic valves for use in the construction of process and service lines to convey industrial fluids at maximum operating temperatures of 60 °C.

The entire range is produced using PVC-U resins compliant with the standards EN 1452 and ISO 4422 and in observance of the requirements of DIN 8063 and EN ISO 15493 for the use of plastic pipes in industrial processes.

Among the main properties and features of the PVC-U range the following can be noted:

• Good chemical resistance: PVC-U resins guarantee excellent chemical resistance with regard to most acids and alkalis, aliphatic hydrocarbons and saline solutions. PVC-U resins are also totally compatible for handling food grade fluids, treated and untreated drinking water, as well as demineralised water according to current national and international standards.
• Good thermal stability: Mostly in the intermediate temperature range between 20 °C and 50 °C, PVC-U finds its ideal application in industrial and water supplies, guaranteeing optimal performance in terms of mechanical resistance, good rigidity, low coefficients of thermal expansion and optimal safety factors in service.
• Lifetime: PVC-U resins feature is an high value in the material strength (Minimum Required Strength MRS ≥ 25.0 Mpa at 20°C) and an extremely extended lifetime.

The entire production range of PVC-U is manufactured in a quality assurance system, according to UNI EN ISO 9001.

FIP PVC-U valves and fittings are approved for use on board ships and other units classified by RINA (Italian Naval Register), Bureau Veritas and Germanischer Lloyd.
