Fuseal PP Pipe Increaser S x S

  Datasheet (PDF)

The Georg Fischer Fuseal PP pipe increaser is engineered for industrial and laboratory corrosive waste drainage systems requiring diameter transitions between large-bore polypropylene piping runs. Designed with socket-by-socket (S x S) ends, this component accommodates both flame-retardant (FR) and non-flame-retardant (NFR) polypropylene systems, providing continuous service up to 82 degrees Celsius (180 degrees Fahrenheit) and intermittent exposure up to 100 degrees Celsius (212 degrees Fahrenheit).

Technical specifications

The Georg Fischer Fuseal PP pipe increaser provides dependable chemical handling and pressure performance in industrial DWV networks. It withstands intermittent discharges up to 100 degrees Celsius and supports pressurized drainage systems up to 50 psi.

• Material options: Flame retardant polypropylene (PPFR) and non-flame retardant polypropylene (PPNFR)
• Joint configuration: Socket by socket (S x S) for Fuseal LD electrofusion loose coil systems
• Continuous operating temperature: Up to 82 degrees Celsius (180 degrees Fahrenheit)
• Intermittent operating temperature: Up to 100 degrees Celsius (212 degrees Fahrenheit)
• Maximum drainage operating pressure: 50 psi
• Chemical resistance: Resistant to alkalis, alcohols, acids, solvents, and salt solutions

Applications

The component serves corrosive waste drainage and chemical DWV infrastructures where aggressive liquid mixtures cause premature degradation of traditional metal systems. Its non-corrosive polypropylene structure eliminates galvanic pitting, rust, scaling, and electrolytic degradation.

Typical installation environments include chemical process plants, life sciences facilities, hospital laboratories, university research centers, and food and beverage processing facilities. For above-ground installations, the integrated pigmentation provides ultraviolet resistance and thermal stabilization against hot reagent discharges.

Installation and jointing

The socket-by-socket configuration integrates into Fuseal LD large-diameter systems using electrofusion loose coils to generate homogenous, leak-free joints. Proper fusion creates a permanent molecular bond that is as robust as the pipe material itself.

Jointing is performed using dedicated electrofusion equipment, such as the Electro Plus fusion machine, which delivers automated cycle control and ambient temperature compensation. Clean square cuts and proper surface preparation using recommended pipe scraping and chamfering tools ensure optimal melt-zone development across large-diameter joints.
