PROGEF PP-H standard reducer PN10 socket fusion

  Datasheet (PDF)

The Georg Fischer PROGEF Standard reducer is a socket fusion fitting for concentric diameter transitions in pressurised thermoplastic pipelines. Moulded from beta-nucleated polypropylene homopolymer (beta-PP-H) to EN ISO 15494 and rated SDR 11 / PN10, it covers metric reductions from d16 to d110 mm. It is intended for process engineers and installers building chemical, water and effluent treatment lines.

Materials and standards

The fitting is moulded from isotactic beta-nucleated polypropylene homopolymer with a minimum required strength of MRS 10 MPa and complies with EN ISO 15494 for pressure-bearing industrial plastic piping systems.

The beta-nucleated structure delivers high mechanical stiffness together with long-term hydrostatic strength, while the homopolymer resin withstands aggressive inorganic acids, caustic alkalis, salt solutions and industrial effluents. Unlike metallic fittings, beta-PP-H is not subject to electrochemical oxidation, pitting or stress corrosion cracking. The PROGEF Standard range is engineered for a 25-year operational life with water at 20 degrees Celsius.

• Material: isotactic beta-nucleated polypropylene homopolymer, MRS 10 MPa
• Manufacturing standard: EN ISO 15494, pressure-bearing industrial piping
• Pressure class: SDR 11, PN10 for socket fusion fittings
• Dimensional coverage: concentric reductions from d16 mm to d110 mm
• Design life: 25 years in continuous service with water at 20 degrees Celsius

Applications

The reducer is used in chemical process plants, water and wastewater treatment facilities and industrial effluent lines, wherever a pipeline changes nominal diameter without leaving the plastic piping system.

The concentric geometry keeps the flow axis constant, so the transition between the two diameters stays hydraulically smooth and avoids excessive turbulence or localised stress concentrations at the change of section. The non-absorbent internal surface does not scale or corrode, which keeps pressure losses stable over the service life of the system and suits the fitting to clean water, treated water and chemically loaded media alike.

Installation and jointing

Both ends are fusion sockets, jointed by heated-tool socket fusion to PROGEF Standard pipes and fittings in the same material and SDR series.

Socket fusion produces a homogeneous, fully welded connection with no adhesives, threads or elastomeric seals in the pressure path, so the joint carries the same chemical resistance as the pipe itself. Use the socket fusion machines and heating tools of the PROGEF Standard programme, and support the line with PP or PE pipe clips and the KLIP-IT pipe support system so that no bending load is transferred into the fusion zone.
