Elbow 45 degrees socket fusion PP-H PN10 PROGEF Standard

  Datasheet (PDF)

The Georg Fischer PROGEF Standard 45 degrees elbow is an industrial pressure fitting engineered from beta polypropylene homopolymer (β-PP-H) for socket fusion jointing in pressurized chemical and water systems. Designed for industrial installers and process engineers, this SDR 11 PN10 fitting ensures smooth, low-turbulence directional changes across piping systems in compliance with EN ISO 15494.

Materials and standards

Manufactured from high-grade isotactic β-PP-H, this fitting complies fully with the dimensional and performance requirements of EN ISO 15494. The specialized crystalline microstructure provides enhanced impact strength and exceptional chemical resistance against acids, alkalis, and inorganic salts.

The robust homopolymer formulation ensures an operational lifespan of 25 years with water at 20°C while maintaining superior stress-crack resistance under continuous industrial operation.

• Material: Beta polypropylene homopolymer (β-PP-H, MRS 10 MPa)
• Nominal pressure rating: PN10 (SDR 11)
• Manufacturing standard: EN ISO 15494
• Connection type: Socket fusion jointing (metric d16–d110 mm)
• Design service life: 25 years for water at 20°C

Applications

PROGEF Standard 45 degrees elbows are suited for conveying aggressive media, treated water, and wastewater across industrial processing facilities. Their smooth interior bore minimizes friction loss, scale buildup, and pressure drop during steady media conveyance.

Typical installations include chemical processing lines, surface treatment workshops, industrial effluent systems, and cooling loops. As an authorised Georg Fischer distributor, BigWeld supplies the complete PROGEF range across Europe, providing certified technical piping solutions for critical infrastructure.

Installation and jointing

Jointing is performed via socket fusion welding, creating a fully homogenous and leak-tight bond between the fitting socket and the pipe spigot. This thermal joining method completely eliminates mechanical seals and prevents leak paths under pressure.

The fittings are compatible with standard workshop and jobsite socket fusion welding equipment across the entire d16 to d110 mm range. Installers must adhere to Georg Fischer welding guidelines, ensuring proper insertion depth and heating times for durable joint integrity.
