PROGEF Adaptor nipple SDR11 PP-H

  Datasheet (PDF)

The Georg Fischer PROGEF Standard adaptor nipple SDR11 forms a high-integrity transition between industrial polypropylene pipework and threaded metal or plastic components. One end is a metric butt fusion spigot suited to conventional heated-tool machines and to infrared (IR) fusion equipment, the other a BSP tapered male thread to ISO 7-1, covering d20 to d63 and R 1/2" to R 2". The body is moulded from beta-PP-H polypropylene homopolymer and rated PN10 at 20 degrees Celsius.

Isotactic, beta-nucleated polypropylene homopolymer gives the fitting high long-term hydrostatic strength, good impact resistance and a design life of 25 years with water at 20 degrees Celsius. The homogeneous structure withstands acids, alkalis, salts and solvents without stress cracking, pitting or erosion, and keeps its mechanical stability across an operating range of 0 to 80 degrees Celsius. Material grade, dimensions and tolerances follow EN ISO 15494 for thermoplastic industrial piping systems, so the nipple matches the SDR11 pipe and the PROGEF Standard fittings it is welded into.

• Material: isotactic polypropylene homopolymer (beta-PP-H), SDR11
• Nominal pressure: PN10, 10 bar at 20 degrees Celsius
• Spigot end: metric butt fusion spigot, heated-tool and IR compatible, d20 to d63
• Threaded end: BSP tapered male thread to ISO 7-1 / EN 10226-1, R 1/2" to R 2"
• Standard: EN ISO 15494, thermoplastic industrial piping systems
• Jointing: butt fusion, infrared (IR) fusion
• Applications: chemical processing, effluent treatment, cooling circuits, demineralised water lines

For installers and piping engineers, the spigot length and wall geometry give repeatable alignment in the clamping jaws and a uniform weld bead through butt fusion or contactless IR cycles. On the threaded side, use a sealing tape or compound compatible with the media and tighten by hand plus a controlled turn: sealing relies on the thread taper, not on excess torque, which would load the polypropylene. BigWeld supplies the PROGEF Standard range, from pipe and butt fusion fittings to valves and fusion machines.
