Revolutionize your hot water infrastructure with Ruisongbuild’s Fiberglass Reinforced PPR (FR-PPR/PPR-FG-PPR) pipes. Featuring an advanced 3-layer composite structure, the inner fiberglass layer reduces thermal expansion by up to 75% compared to standard PPR pipes. This ensures your piping remains straight and stable even at constant high temperatures of 95°C. Engineered to DIN 8077/8078 and rated up to PN25, our FR-PPR is the ultimate choice for high-rise plumbing, central heating, and HVAC chilled water systems where durability and precision are non-negotiable.

Ruisongbuild FR-PPR: The Engineering-Grade Multilayer Solution
Standard PPR pipes often struggle with expansion and deformation in long-run hot water lines. Ruisongbuild’s Fiberglass Reinforced PPR (FR-PPR) solves this problem through a sophisticated 3-layer co-extrusion process. By integrating a specialized fiberglass-PPR compound layer between two layers of premium virgin PPR, we’ve created a pipe that combines the hygiene of plastic with the rigid stability of metal.
The 3-Layer Composite Structure
-
Inner Layer: Smooth, food-grade PPR for low friction and zero contamination.
-
Middle Layer: Fiberglass-PPR compound, providing high mechanical strength and ultra-low thermal expansion.
-
Outer Layer: High-impact resistant PPR for external protection and UV stability.
Advanced Technical Specifications
-
Standards: DIN 8077/8078, ISO 15874.
-
Thermal Expansion Coefficient: Approximately 0.035 mm/m·K (vs 0.15 for standard PPR).
-
Pressure Ratings: PN20, PN25.
-
Working Temperature: Continuous 70°C, peak up to 95°C.
-
Available Sizes: 20mm to 160mm.
-
Expansion Reduction: 75% less expansion than conventional PPR.
Why Choose Ruisongbuild FR-PPR for Your Project?
-
Exceptional Rigidity (No Sagging): Stays straight even in horizontal hot water runs, requiring fewer support clips and providing a professional aesthetic.
-
Higher Flow Rates: Thinner walls (with higher pressure ratings) allow for a larger internal diameter (ID) compared to standard PPR.
-
Enhanced Temperature Resistance: The fiberglass layer prevents the pipe from softening at high temperatures, increasing the safety factor for central heating.
-
Easy Installation: Still uses the standard Socket Heat Fusion welding. No special peeling tools required for the fiberglass layer.
Primary Applications
-
High-Rise Buildings: Hot water risers and distribution networks.
-
HVAC Systems: Chilled and hot water piping for central air conditioning.
-
Solar Heating Systems: High-temperature rooftop solar collector lines.
-
Industrial Fluids: Transporting fluids where pipe stability is critical.
Frequently Asked Questions (FAQs)
Q1: What is the difference between FR-PPR and standard PPR?
A: The main difference is the thermal expansion. FR-PPR has a fiberglass-reinforced middle layer that reduces heat expansion by up to 75%. It is also stiffer, meaning it won’t sag or bend when transporting hot water over long distances, unlike standard PPR.
Q2: Do I need special tools to weld FR-PPR pipes?
A: 不. Ruisongbuild FR-PPR pipes are designed for standard socket heat fusion. They use the same welding temperatures and tools as regular PPR pipes. Unlike aluminum-PPR pipes, there is no need to peel the outer layer before welding.
Q3: Is FR-PPR safe for drinking water?
A: Yes. The inner layer that comes into contact with water is made of 100% virgin, non-toxic PPR resin. It is completely safe for potable water and meets international health standards.
Q4: Why is FR-PPR better for HVAC systems?
A: HVAC systems often involve significant temperature fluctuations. The low-expansion property of FR-PPR prevents stress on joints and fittings caused by expansion and contraction, significantly reducing the long-term risk of leaks in large commercial buildings.
Q5: What is the pressure rating of Ruisongbuild FR-PPR?
A: Our FR-PPR is typically available in PN20 and PN25. Due to the reinforcement layer, it often offers higher burst pressure safety compared to a standard PPR pipe of the same wall thickness.
