Polypropylene PP-R pipes with glass fiber

suitable for the transport of potable water

Image

Triple-layer piping with a middle layer composed of special fibers that reduce linear heat expansion by up to 75% compared to “normal” PP-R SDR 6 single-layer tubing.

These characteristics also reduce wall thickness, thereby increasing water transport by more than 20% compared to “normal” PP-R SDR 6 single-layer tubing.

APPLICATIONS Tubing especially suited for sanitary plumbing systems, mechanized systems, (HVAC), and the transport of compressed air or industrial liquids

TECHNICAL SPECIFICATIONS
Materials: Inner layer in PP-RCT HOR (polypropylene random copolymer, high crystallinity, high temperature, high oxidation resistance); middle layer in PP-RF (polypropylene random copolymer reinforced with glass fiber); and outer layer in PP-R (polypropylene random copolymer).

Heat conductivity at 20°C: 0.19 W/mk
Expansion coefficient: at 0.035 mm/mk
Internal roughness: 0.007 mm
Color: Green with red stripes, white tube interior


Tubing intended for the transport or liquids at a constant maximum working temperature of 70°C for 50 years at a maximum pressure of 12,5 bar.

PERFORMANCE STANDARDS
Produced in compliance with the principal international standards, including UNI EN ISO 15874, DIN 8077-8078, and ASTM. Compliant with all standards for the transport of potable water, for the transport of hot and cold liquids intended for human consumption, and for HVAC and compressed air systems.

Polypropylene PP-R pipes with glass fiber

suitable for the transport of potable water

Image

Triple-layer piping with a middle layer composed of special fibers that reduce linear heat expansion by up to 75% compared to “normal” PP-R SDR 6 single-layer tubing.

Characteristics such as these also make it possible to reduce wall thickness which, in turn, increases water transport by more than 40% compared to “normal” PP-R SDR 6 single-layer tubing.

APPLICATIONS
Tubing especially suited for mechanized systems, including HVAC systems and the transport of compressed-air or industrial liquids. 

TECHNICAL SPECIFICATIONS
Materials: Inner layer in PP-R HTS (polypropylene random copolymer Super 80 High Thermal Stabilization); middle layer in PP-RF (polypropylene random copolymer reinforced with glass fiber); and outer layer in PP-R (polypropylene random copolymer).

Heat conductivity at 20°C: 0.19 W/mk
Expansion coefficient: at 0.035 mm/mk
Internal roughness: 0.007 mm
Color: Blue with gray stripes, white tube interior

Tubing intended for transport of liquids at a maximum constant working temperature of 80°C for 25 years at a maximum pressure of 8 bar and a maximum limit temperature 95°C at 6.10 bar for 10 years.

PERFORMANCE STANDARDS
Produced in compliance with the UNI EN ISO 15874-2, 15874-5, and DIN 8077-8078 standards.
