Polypropylene pipes with fiberglass
Structure
The inner and outer layers are polypropylene (PP-R 100), the middle layer is composite (polypropylene + fiberglass).
Service life
At least 50 years under operating conditions
Working pressure
Usually PN20 or PN25
Heat resistance
Maximum temperature - 95°C
Linear expansion
Reduced to 0.033-0.05 degrees C, which eliminates significant sagging of pipes when heated
Installation
Are soldered using the socket welding method
Description
The fiberglass-reinforced PPR (polypropylene) pipe (PPR-GF-PPR) is a three-layer pressure pipe designed for hot/cold water supply and heating systems.• Structure: Inner and outer layers — polypropylene (PP-R 100), middle layer — composite (polypropylene + fiberglass).• Service life: At least 50 years under proper operating conditions.• Working pressure: Typically PN20 or PN25.• Heat resistance: Maximum temperature is 95°C; recommended for heating systems with a coolant temperature not exceeding 80-85°C.• Linear expansion: Reduced to 0.033-0.05 mm/(m·°C), which prevents significant pipe sagging when heated.• Installation: Joined by socket fusion welding. Do not require peeling (shaving) before welding, which accelerates installation.
