PROGEF PP-H Adaptor Socket Rp SDR11 PN10

  Datasheet (PDF)

The Georg Fischer PROGEF PP-H SDR11 PN10 adaptor socket provides a robust transition between polypropylene piping systems and threaded components. Designed for industrial fluid handling and chemical processing, this precision-moulded fitting combines a butt fusion spigot with an Rp female thread reinforced by an austenitic stainless steel ring. It delivers long-term hydrostatic strength and leak-tight reliability across operating pressures up to 10 bar at 20 degrees Celsius.

Technical specifications

The PROGEF adaptor socket pairs a standard SDR11 butt fusion end with a parallel female thread for secure mechanical interfacing. Engineered for high-integrity chemical and industrial fluid networks, it ensures smooth flow transitions across diameters from d20 mm to d63 mm.

• Nominal pressure: PN10 (10 bar at 20 degrees Celsius).
• Dimensional ratio: SDR11 with consistent wall thickness.
• Fusion spigot: Calibrated for butt fusion and contactless infrared (IR) jointing.
• Threaded connection: Parallel female thread Rp manufactured to ISO 7-1.
• Reinforcement: Grade A2 stainless steel ring to absorb hoop stress.
• Design life: Rated for a 25-year service life under standard conditions.

Materials and standards

Manufactured from beta-nucleated polypropylene homopolymer (beta-PP-H), this fitting exhibits superior crystalline morphology, high impact strength, and exceptional chemical resistance. The integration of an external austenitic stainless steel reinforcing ring safeguards the thermoplastic female thread against mechanical deformation.

The homogeneous beta-PP-H compound delivers excellent resistance against aggressive acids, alkalis, and industrial effluents, preventing stress cracking during continuous duty. The external A2 stainless steel collar absorbs radial stress caused by over-torquing during valve or sensor installation, maintaining joint integrity under thermal expansion and contraction cycles.

Installation and jointing

The fitting is jointed on the spigot side using conventional hot-plate butt fusion or contactless infrared (IR) welding equipment. On the transition side, the reinforced Rp thread connects directly to metallic or compatible plastic threaded apparatus.

Installers should align the SDR11 spigot according to standard thermoplastic butt fusion parameters to produce clean, homogeneous weld beads. For the threaded connection, use virgin PTFE sealing tape without exceeding recommended torque values, ensuring reliable sealing while the stainless steel ring protects the PP-H body from radial cracking.
