Products information
Product Description: Aquatherm Green PPR Pipe SDR 7.4 MF Ø20x2.8mm (Item No. A70708)
The Aquatherm A70708 is a premium, multi-layer, fiber-reinforced polypropylene-random (PP-R) pipe, part of the advanced "Aquatherm Green Pipe" system. Manufactured in Germany, the MF (Multi-Layer Faser/Fiber) technology provides enhanced stability and reduced thermal expansion compared to standard homogeneous PPR pipes. This pipe is engineered for highly efficient and durable hot and cold water systems.
Key Technical Specifications
| Feature | Specification |
|---|---|
| Product Name | Aquatherm Green Pipe MF (Multi-Layer Fiber) |
| Item Number | A70708 |
| Outer Diameter (OD) | 20 mm |

| Pressure Rating | Designed for high operating pressures, typically rated PN16 |
| Operating Temperature | Suitable for constant use up to 70°C and intermittent peak temperatures up to 95°C |
| Linear Expansion Coeff. | Very low (approx. 0.035 mm/m·K), similar to metal pipes |
Features and Benefits
- Reduced Linear Expansion: The primary advantage of the MF (fiber-reinforced) structure is a 75% reduction in linear thermal expansion compared to conventional solid plastic pipes. This minimizes pipe sagging and allows for greater support distances during installation.
- Corrosion-Free: The pipe is entirely non-metallic, ensuring it will never corrode, rust, or scale, guaranteeing pure water quality and consistent flow rates over time.
- Hygienic and Food Safe: The inert Fusiolen® PP-R material is non-toxic and certified for use in potable (drinking) water systems worldwide.
- Durable Performance: Engineered for longevity with a projected lifespan of over 50 years under standard operating conditions.
- Leak-Proof Connections: Installation uses the reliable heat fusion welding process, creating a permanent, homogeneous, and leak-proof bond between the pipe and fittings.
- Improved Flow Rate: Due to the reinforced stability, the wall thickness can be slightly optimized, increasing the internal bore and flow rate compared to other standards at the same pressure ratings.
- Lightweight: The material is significantly lighter than metal piping, simplifying transport and installation.
Typical Applications
The A70708 pipe is a versatile solution used in a wide range of demanding building services:
- Domestic hot and cold potable water systems.
- High-temperature heating systems (radiator connections, underfloor heating).
- Chilled water and cooling water systems (HVAC).
- Compressed air and industrial fluid transfer systems.
