Fiberglass Reinforced PPR Pipe (FR-PPR) Low Expansion PN25

Description

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

1. Inner Layer: Smooth, food-grade PPR for low friction and zero contamination.

2. Middle Layer: Fiberglass-PPR compound, providing high mechanical strength and ultra-low thermal expansion.

3. 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: No. 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.
