PROGEF PP-H Fixpoint Fitting SDR17.6 PN6

  Datasheet (PDF)

The PROGEF Standard SDR17.6 PN6 fixpoint fitting manufactured by Georg Fischer (GF Piping Systems) is an engineered thermoplastic piping component designed to securely anchor pipeline sections and absorb axial mechanical stresses caused by thermal expansion and contraction. Fabricated from high-grade isotactic beta-polypropylene homopolymer (beta-PP-H), this fitting provides the mechanical stiffness, tensile integrity, and creep rupture strength required to establish rigid anchoring points across industrial process networks. Operating at a nominal pressure rating of PN6 (6 bar at 20 degrees C), the SDR17.6 configuration is optimized for medium-duty pressure installations, industrial water treatment, chemical transfer, and wastewater handling where uncontrolled thermal movement could compromise pipe runs, inline valves, or connected equipment.

Manufactured in full compliance with EN ISO 15494 for polypropylene piping systems, each PROGEF fixpoint fitting features precision spigot ends compatible with conventional heated tool butt welding according to DVS 2207 standard parameters, as well as non-contact infrared (IR) fusion machines. IR fusion ensures reproducible joint quality, minimal weld beads, and smooth hydraulic characteristics. The reinforced exterior shoulder geometry safely transfers high axial expansion and contraction thrusts into external steel brackets, pipe clamps, or building structures without generating localized stress concentrations on the pipe barrel, preventing premature fatigue or pipe buckling during continuous thermal cycling.

As an authorised Georg Fischer distributor, BigWeld provides genuine PROGEF components with full technical support and factory documentation. The chemically resilient beta-PP-H material exhibits high resistance to inorganic salts, acids, and caustic solutions across broad industrial operating regimes, engineered for a 25-year operational service life when conveying water at 20 degrees C. The fitting is suited for mounting within industrial pipe racks, plant rooms, and chemical processing facilities requiring defined thermal expansion zones.
