Schedule 80 PPNFR Pipe

  Datasheet (PDF)

Georg Fischer Fuseal Schedule 80 PPNFR pipe is a heavy-wall non-flame retardant polypropylene piping solution designed for corrosive chemical waste and drainage systems. Engineered primarily for below-grade laboratory, industrial, and institutional DWV installations, it provides superior resistance to harsh chemicals, acids, and industrial solvents. Supplied in standard 20-foot lengths, the pipe handles continuous operating temperatures up to 180 degrees F (82 degrees C) and intermittent thermal discharges up to 212 degrees F (100 degrees C).

Technical specifications

The Schedule 80 PPNFR pipe provides heavy-duty wall construction and reliable chemical containment for gravitational and low-pressure corrosive drainage networks. It operates dependably under vacuum and pumped drainage cycles with system pressure ratings up to 50 psi for electrofusion assemblies.

• Material: Non-flame retardant polypropylene (PPNFR)
• Wall schedule: Heavy-duty Schedule 80 wall profile
• Standard length: 20-foot straight pipe sections
• Continuous service temperature: Up to 180 degrees F (82 degrees C)
• Intermittent discharge temperature: Up to 212 degrees F (100 degrees C)
• Joint compatibility: Fuseal electrofusion collars and Fast-Lock mechanical fittings

Applications

The piping is formulated specifically for below-grade corrosive waste drainage where non-flame retardant polypropylene is permitted by local plumbing codes. It safely collects and conveys aggressive effluent mixtures discharged from industrial manufacturing, health science facilities, and educational research environments.

Fuseal Schedule 80 PPNFR systems routinely replace conventional metallic drain lines that fail prematurely due to aggressive chemical degradation or electrolytic corrosion. Primary deployment environments include:

• Corrosive chemical waste and laboratory DWV systems
• Life sciences and pharmaceutical production facilities
• Chemical process industry drainage networks
• Food and beverage industrial processing lines
• Hospital and academic research laboratories

Materials and standards

Manufactured from chemically inert non-flame retardant polypropylene, the pipe resists the corrosive action of alkalis, alcohols, dilute mineral acids, aqueous acid salts, and varied industrial solvents. The non-metallic structure will not rust, pit, scale, corrode, or experience electrolytic deterioration throughout its service life.

The material is subject to attack only by strong oxidizing acids and can be weakened by exposure to certain chlorinated hydrocarbons and specific organic solvents. The heavy Schedule 80 cross-section provides enhanced impact resistance and structural rigidity, making it suitable for direct-burial trench conditions below grade.
