3. PPR Pipe Manufacturing Process Explained
Raw Material Feeding & Extrusion Sizing & Cooling Cutting ISO/ANSI QC & Marking
Step-by-step:
1. Raw Material: 100% virgin PP-R Type 3 granules (Borealis HE3490-LS/Fujian Sinopec certified), ensuring food-grade safety and mechanical robustness.
2. Feeding & Extrusion: Granules auto-fed to precision screw extruders (German Battenfeld/Cincinnati lines), melted at 180–230°C for homogeneous fusion.
3. Sizing & Cooling: Molten material extruded through a calibrated die, sized, and water-cooled for roundness & strict OD tolerance (±0.1 mm).
4. Cutting: Pipes are cut to 4/5/6m standard length via CNC saw, minimizing burrs.
Quality Inspection: Online laser sensors & hydrostatic burst test, complying with ISO 15874 and ANSI/NSF 14/61. Each pipe marked with lot/production date for full traceability.
Key Manufacturing Technologies: High-speed twin-screw extrusion, laser OD control, in-line ultrasound wall measuring, robotic stacking. These innovations deliver consistency, low internal roughness (<0.01mm), and enhanced lifespan (>50 years).

Frequently Asked Questions: PPR Pipe Technology

Q1. What is PPR and why is PP-R Type 3 preferred?
PPR (Polypropylene Random Copolymer) Type 3 features high random copolymer content for superior strength, weldability, and heat resistance—ideal for hot/cold water, compared to Type 1/2 or PP-H.
Q2. What are PN (Pressure Nominal) ratings?
PN refers to rated working pressure (bar) at 20°C (PN10/PN16/PN20/PN25). PN25 pipes are for high-pressure commercial or central heating.
Q3. What standards are relevant for PPR Pipe?
Major standards: ISO 15874 (global), DIN 8077/8078 (EU), ANSI/NSF 14/61 (US), WRAS (UK)—ensure pipe quality, hygiene, and compatibility.
Q4. How is PPR pipe joined and is special equipment needed?
Fusion welded using a socket fusion or butt fusion tool (typically 260°C). Joints are permanent/seamless; no solvent or glue required. Mechanical fittings also available.
Q5. What is SDR (Standard Dimension Ratio) and why does it matter?
SDR = Pipe Outside Diameter / Wall Thickness; lower SDR = thicker pipe = higher pressure resistance. SDR6, SDR7.4, SDR9 are common grades.
Q6. What is the expected service life?
Up to 50 years @ 20°C, PN20. Certified by ISO 9080 testing. Actual field feedback confirms superior longevity in diverse climates.
Q7. Does PPR pipe resist scaling and biofilm?
Yes. Ultra-smooth inner walls (<0.009mm) minimize scale and bacteria adhesion, proven by independent lab tests (TÜV Rheinland 2023).
