Viega introduces Pexfit Pro Fosta pipeline system for drinking water and heating systems

Germany-based company Viega's new pipeline system for drinking water and heating systems called Pexfit Pro Fosta, is an innovative installation product under composite pipe system, and is flexible and durable as expected.

Made of physically cross-linked polyethylene (PE-Xc), these pipes are temperature and pressure-resistant as compared to CPVC pipes, insensitive to corrosion and incrustation. A Pexfit Pro Fosta series variant has three layers: PE-Xc internal pipe, an aluminium layer, and a white external coating - making the pipe form stable, that is, once bent into close radii, the pipe permanently retains this shape, thereby eliminating the need for elbow joints.

Pexfit Pro system comes with the advantage of Viega's press connection technology to ensure leakage-proof joints. Once crimped using the Viega press tool (tool calibration and bevelling are not required), these joints become permanently leak-proof. Whether made of polyphenylsulfone (PPSU) or red brass, Viega's press connectors feature the SC-Contur, which makes unintentionally un-pressed joints easily visible during a leakage test, or when the system is filled.

A complete installation can be inspected centrally on the manometer as long as the components are all fitted with the SC-Contur. Only threaded connectors must be inspected individually in advance; central inspection is a huge advantage for those executing large projects. The Pexfit Pro Fosta pipes are available in 16 to 63 mm. An extensive range of Pexfit Pro connectors with press connections also allow quick and uncomplicated crossover to metal pipe systems.
