Standard Butt Fusion Reducer S5/SDR11 PP-H PN10

  Datasheet (PDF)

The Georg Fischer PROGEF Standard SDR11 reducer is an injection-moulded thermoplastic fitting engineered for permanent, high-integrity diameter transitions in industrial pressure piping systems. Manufactured from polypropylene homopolymer (beta-PP-H) with an MRS of 10 MPa in metric sizes d20 to d315, and polypropylene random co-polymer (PP-R MRS 10 MPa) in sizes d355 to d500, this component complies with EN ISO 15494. Designed for a continuous pressure rating of PN10 (10 bar at 20 degrees C), it conveys demanding chemicals, process water, and industrial effluents over a 25-year service life.

Featuring outstanding chemical resistance against acids, alkalis, and inorganic salts, this reducer prevents scaling, cavitation wear, and electrochemical corrosion across an operating temperature range from 0 to 80 degrees C. The concentric transition geometry ensures uniform fluid dynamics and hydraulic efficiency, minimising turbulence, head loss, and stress concentrations along the pipeline axis. The spigot ends feature precise dimensional tolerances matching SDR11, enabling jointing through conventional butt fusion per DVS 2207-11 as well as contactless infrared (IR) welding.

As an authorised Georg Fischer distributor, BigWeld supplies the complete PROGEF Standard piping portfolio across Europe to mechanical contractors, plant engineers, and industrial facilities. The butt-weldable reducer integrates seamlessly into chemical distribution lines, wastewater treatment plants, and utility loops where metallic systems fail. Homogeneous molecular fusion achieved during welding ensures high joint integrity equal to the pipe itself, providing dependable leak-tight performance under cyclical pressure.
