Newpipe Multilayer Pipes: Safe, Hygienic Water & Efficient Heating
As global safety and drinking-water standards evolve, single-metal or single-layer plastics are giving way to multilayer technology. Newpipe’s five-layer PE-AL-PE pipe blends aluminum with specialty polyethylene to deliver the best of both worlds—metal rigidity with polymer flexibility—in one system. Its sandwich structure brings oxygen diffusion close to zero, minimizing corrosion, bacterial growth, and heat loss—critical for underfloor heating and potable-water networks.
Structure & Manufacturing
The inner and outer layers are PE-X or PERT. An installation-grade adhesive bonds them to a longitudinally welded aluminum core. The result is a pipe that meets PN16 and withstands continuous 95 °C operation. Nominal diameters from 16 to 63 mm give engineers freedom from small home loops to central risers.
Table 1 – Selected Technical Specifications (Newpipe)
| Nominal Diameter (mm) | Total Wall Thickness (mm) | Operating Pressure at 20 °C (bar) | Manual Bending Radius (mm) | Unit Weight (g/m) |
|---|---|---|---|---|
| 16×2.0 | 2.0 | 16 | 80 | 115 |
| 20×2.25 | 2.25 | 16 | 100 | 160 |
| 25×2.5 | 2.50 | 16 | 125 | 225 |
| 32×3.0 | 3.00 | 16 | 160 | 335 |
| 40×3.5 | 3.50 | 16 | 200 | 520 |
Fittings & Installation
Newpipe press, compression, and threaded fittings—machined from nickel-plated brass—deliver permanent sealing without tape or paste. A stainless press sleeve with a color indicator confirms correct pressing. On large projects, U and TH jaws speed installation. Compression couplers are handy for spot repairs or compact domestic layouts.
Table 2 – Product & Fitting Compatibility
| Product | Diameter (mm) | Compatible Fitting Types |
|---|---|---|
| PE-AL-PE pipe | 16 | Press / Compression |
| PEX-AL-PEX pipe | 20 | Press / Compression |
| PERT-AL-PERT pipe | 25 | Press |
Examples of compatible components include 90° press elbows (16 mm) and compression tees (20 mm).
Applications Beyond Buildings
- Large-area underfloor heating; markedly lower hydraulic head and heat loss.
- Potable-water distribution in hotels and hospitals; oxygen-tight with no metallic ion leaching.
- Radiant cooling; resistant to thermal shock from chillers.
- Food & pharma plants; ultra-smooth bore and sanitary approvals.
- Light compressed-air and pneumatic lines; multilayer body mitigates hydrogen-related cracking.
Key Advantages at a Glance
- Service life >50 years under standard operating conditions.
- Roughness ≤ 0.007 mm; minimal pressure drop and long-term scale resistance.
- Lower specific weight than copper; easier handling and reduced dead load.
- Stress-crack resistance; ideal for mildly acidic or basic environments.
- Fast, flameless installation; safer jobsites than metal welding.
After-Sales & Certifications
Newpipe holds DVGW (Germany), NSF (drinking-water), and Iran National Standard 1476-1 approvals. A 10-year warranty applies when installed correctly with original fittings. A traceability system lets users verify each coil or fitting via its QR code.
