PROGEF Standard PP-H Butt Fusion End Cap SDR11 PN10 d20-d225

  Datasheet (PDF)

The Georg Fischer PROGEF Standard PP-H end cap provides a permanent, leak-tight termination for pressure lines in industrial piping. Moulded in isotactic polypropylene homopolymeride (beta-PP-H), it carries plain spigot ends for butt fusion and infrared fusion, runs in SDR 11 at PN10 and covers the metric range d20 to d225 mm. BigWeld supplies it as an authorised Georg Fischer distributor.

Materials and standards

The cap is produced from beta-PP-H with MRS 10 MPa and conforms to EN ISO 15494 for plastic piping systems with long-term hydrostatic properties. The beta-crystalline structure of the polymer gives high impact strength and rigidity, together with resistance to acids, alkalis, inorganic salts and demineralised water.

• Material: isotactic polypropylene homopolymeride (beta-PP-H), MRS 10 MPa
• Dimension ratio: SDR 11 over the whole range
• Nominal pressure: PN10 at 20 degrees Celsius
• Dimensional range: metric outside diameters d20 to d225 mm
• Standard: EN ISO 15494, plastic piping systems
• Design life: 25 years with water at 20 degrees Celsius

Installation and jointing

The spigot ends are dimensioned for heated-tool butt fusion and for automated infrared fusion, both carried out in accordance with the DVS 2207 welding guidelines. The joint is homogeneous and gasket-free, formed between identical PP-H sections, so the terminated end keeps the chemical and mechanical behaviour of the pipe itself.

Matching pipe wall thickness is essential: the cap is an SDR 11 component and is fused to SDR 11 pipe so that the melt bead builds evenly around the full cross-section. Pressure, heating time and cooling time follow the welding parameters for the wall thickness being joined. Within the PROGEF Standard range the cap can be combined with butt fusion fittings, valves and PP-GF30 backing flanges from the same system.

Applications

PROGEF Standard PP-H components are used for water, wastewater and effluent treatment and for a wide range of chemical applications. The end cap closes line ends, unused branches and sections reserved for later extension, keeping the termination at the same pressure class and material grade as the rest of the network.
