PROGEF butt fusion outlet flange adaptor PP-H SDR17.6 PN6

  Datasheet (PDF)

The Georg Fischer PROGEF Standard butt fusion outlet flange adaptor is engineered from high-grade isotactic polypropylene homopolymer (beta-PP-H) for pressure-bearing industrial piping systems. Specifically designed with an SDR 17.6 geometry rated for nominal operating pressures of PN6 (6 bar at 20 degrees Celsius), this specialized fitting delivers an optimized seating interface for Georg Fischer Type 369 wafer check valves. By ensuring accurate axial alignment and unobstructed disc clearance, the adaptor prevents internal mechanical interference and premature wear within flanged valve assemblies across chemical lines, wastewater treatment plants, and process cooling loops.

Manufactured in compliance with EN ISO 15494 standards and DVS 2207 welding guidelines, this PROGEF fitting is fully compatible with heated-tool butt fusion and contactless infrared (IR) fusion jointing. The controlled beta-nucleated crystalline morphology of the PP-H material provides outstanding resistance to aggressive inorganic acids, alkalis, salts, and chemical effluents, alongside excellent resilience against environmental stress cracking. Operating across a temperature range from 0 degrees to 90 degrees Celsius, with short-term peaks up to 100 degrees Celsius, it retains long-term hydrostatic strength throughout a design life of 25 years.

Available across outer diameters from d40 mm to d315 mm, the fitting features an extended spigot design facilitating secure clamping in standard butt fusion equipment. Its precision flange face coordinates smoothly with metric backing flanges and profile gaskets, creating dependable, leak-free mechanical joints resistant to operational vibrations. As an authorised Georg Fischer distributor, BigWeld supplies industrial piping contractors with certified thermoplastic piping systems engineered for maximum operational safety where metallic materials fail.
