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

Private Label PEX Pipe: Build Your Own Brand

A distributor who imports generic coils competes on one thing: price. A private label pex pipe program changes that math, because the brand printed down the length of the tube belongs to you, not to the factory or the three other importers buying from the same line. That single change is the difference between reselling

PEX Pipe Lifespan: Chlorine, UV & Fitting Failures

Ask ten plumbers about PEX pipe lifespan and you’ll hear numbers from 25 to 100 years. The honest answer sits in a narrower band: quality PEX is engineered for a 40-to-50-year design life, and most reputable makers back it with a 25-year warranty. That rating holds on one condition. Four enemies have to be kept

PEX Pipe Size Chart for Residential & Commercial

A PEX pipe size chart answers the one question that decides whether a plumbing job works or fails: is this line big enough to carry the water without starving the fixture at the end? Picking a PEX pipe size is not guesswork, and it is not “whatever’s on the truck.” It comes down to nominal
