PROGEF PP-H Socket Fusion Barrel Nipple d16-110 PN10

  Datasheet (PDF)

The Georg Fischer PROGEF Standard barrel nipple is an engineered piping component manufactured from beta-nucleated polypropylene homopolymer (beta-PP-H). Designed specifically for socket fusion jointing across metric diameters from d16 up to d110, this double-spigot nipple enables the shortest possible connection distance between socket fittings, valves, and compact pipeline assemblies. Its low-profile structural geometry makes it an indispensable fitting for skid builders, OEM manufacturers, and industrial installers working within constrained spaces.

Conforming to EN ISO 15494 for industrial thermoplastic pressure systems, this barrel nipple is rated for a nominal working pressure of PN10 (SDR 11) at 20 degrees Celsius, with an operational design service life of at least 25 years in water and compatible process fluids. The isotactic beta-PP-H compound delivers elevated hydrostatic durability, high tensile stiffness, and reliable resistance to environmental stress cracking. The material withstands aggressive chemical environments, including mineral acids, caustic alkaline solutions, and process effluents, operating across broad temperature envelopes where standard polyolefins fail.

The calibrated fusion spigots on both ends are fully compatible with standard heated-tool socket fusion equipment. During installation, the controlled heating cycle and subsequent insertion into socket fittings generate a homogeneous, weld-bonded joint without mechanical weaknesses or potential leak paths. The uniform interior surface profile prevents fouling, scaling, and turbulence, preserving pressure integrity and laminar flow characteristics throughout the network. As an authorised Georg Fischer distributor, BigWeld supplies the entire PROGEF metric range from d16 to d110 mm, supporting engineering contractors with verified technical performance.
