PP-H Flange Adaptor PN10 Socket Fusion d20-d110

  Datasheet (PDF)

Georg Fischer PROGEF Standard PP-H flange adaptors provide a reliable, pressure-rated transition from socket fusion piping networks to flanged process equipment, pumps and valves. Engineered for industrial chemical handling, water treatment and process utilities, this metric fitting features an integrated O-ring groove and an MRS 10 strength classification. Operating at pressures up to 10 bar (PN10) at 20 degrees C, it ensures tight compression sealing across sizes from d20 to d110 mm.

Technical specifications

The PROGEF flange adaptor is engineered for PN10 nominal pressure performance with SDR 11 socket dimensions across the entire d20 to d110 mm metric range. Its machined O-ring groove guarantees positive sealing against flat or serrated mating faces when bolted using standard backing rings.

• Material: Isotactic homopolymer polypropylene (beta-PP-H), MRS 10
• Nominal pressure: PN10 (10 bar at 20 degrees C)
• Dimensional range: d20 to d110 mm socket fusion (SDR 11)
• Sealing profile: Jointing face with machined groove for elastomeric O-rings
• Manufacturing standard: EN ISO 15494
• Design lifetime: 25 years operational service with water at 20 degrees C

Materials and standards

Manufactured strictly in accordance with EN ISO 15494, these adaptors utilize high-grade beta-nucleated PP-H to achieve exceptional chemical and thermal resistance.

The material structure exhibits outstanding resistance to inorganic acids, alkalis, salt solutions and process effluents, preventing degradation and stress cracking in aggressive industrial environments. Its smooth internal bore resists encrustation, scale build-up and biofilm adhesion, maintaining optimal hydraulic flow characteristics throughout decades of continuous duty. Combined with either EPDM or FKM elastomeric O-rings, the connection isolates chemical lines without risking seal degradation.

Installation and jointing

Jointing is executed via standard metric socket fusion tooling, producing a homogeneous, leak-tight weld between the fitting socket and PP-H pipe spigot.

The precision-machined socket depth provides reproducible insertion and controlled melt distribution without reducing the internal waterway diameter. Bolted connections are assembled using glass-fibre reinforced polypropylene (PP-V) or steel-reinforced backing flanges, which distribute clamping torque evenly across the sealing face. This flanged joint allows quick disassembly for valve maintenance, pump replacement or system inspection without cutting the pipeline. Supplied across Europe by BigWeld, an authorised Georg Fischer distributor, this PROGEF component guarantees rapid assembly and industrial reliability.
