PPR (Polypropylene Random Copolymer) is formed by copolymerizing propylene and ethylene monomers
Unique molecular structure provides both rigidity and flexibility (Vicat softening point ≥131℃)
Enhanced heat resistance through antioxidants and thermal stabilizers

2. High-Temperature Impact Mechanism

Short-term exposure (below 95℃): Stable physical properties
Long-term exposure (above 70℃): Focus on creep resistance and oxidation degradation
Extreme temperature: Tolerates 110℃ briefly, continuous use below 95℃

3. Technical Advantages of IFAN PPR Pipes

Uses Borealis RA130E raw material (top global PPR resin)
Triple-layer co-extrusion structure (inner layer + reinforcing layer + outer layer)
Complies with ISO 15874 drinking water standard
50-year service life guarantee (based on EN 805)

4. High-Temperature Performance Comparison

Test Item	IFAN PPR Pipe	Standard PPR Pipe	Metal Pipe
Long-Term Temp	70℃ @ 1.0MPa	60℃ @ 0.8MPa	120℃+
Short-Term Pressure	95℃ @ 1.5MPa	85℃ @ 1.2MPa	150℃+
Linear Expansion	0.15mm/m·℃	0.16mm/m·℃	0.012mm/m·℃

5. Installation Recommendations

Use matching ifan PPR fusion fittings (ensure welding depth)
Install fixed brackets every 3 meters on straight sections
Install automatic air vents at system apex
Recommend water temperature ≤70℃ for continuous use

6. Typical High-Temperature Applications

Central heating systems (70-80℃ hot water)
Solar thermal systems (tank to collector sections)
Industrial cooling systems (≤95℃ heat transfer media)
Underfloor heating (≤60℃ supply water)

7. Advantages Over Other High-Temp Pipes

Compared to copper: 40% cost reduction, no electrochemical corrosion
Compared to PB: 25% higher pressure resistance, better creep resistance
Compared to PE-RT: 30℃ higher long-term heat resistance

8. IFAN’s Quality Assurance

100% hydrostatic testing for every batch
Free thermal expansion calculation service
Custom high-temperature piping solutions
Nationwide 24-hour technical support

What is the Standard Pipe Fitting Size?

Pipe fitting sizes follow standardized measurements worldwide. Understanding these standards ensures proper connections and system efficiency. The most common sizing systems include nominal pipe size (NPS), international standards (ISO), and metric measurements. Understanding Nominal Pipe Size (NPS) NPS represents the approximate internal diameter of pipes. Standard sizes range from 1/8 inch to 48 inches. However,

Is a Manifold the Same as a Valve?

When working with piping systems, many professionals encounter confusion between manifolds and valves. While both components control fluid flow, they serve distinctly different purposes in industrial applications. What Is a Valve? A valve is a device that controls the flow of fluids through a pipe. It can start, stop, or regulate flow by opening, closing,

What is the Difference Between a Pipe and a Manifold?

When working with fluid systems, understanding the distinction between pipes and manifolds is crucial. These components serve different purposes in pipeline networks. Let’s explore their unique characteristics and applications. What is a Pipe? A pipe is a hollow cylinder designed to transport fluids from one location to another. Pipes create linear pathways for gas, liquid,
