The Flexalen PB piping system is an SDR11 thermoplastic piping system made of PB-1 (Polybutene-1). PB-1 is used worldwide in applications where high temperature and pressure performance is combined with flexibility, such as large-scale building projects, district energy networks, heating and cooling, and plumbing installations.
PB-1 pipes are available as stick or as long length coil and connected using either mechanical or welded (socket, fusion and butt) fittings.
