5 Misconceptions about Synthetic Piping Systems
For over 30 years, the Henco multilayer pipe has set the standard in the installation industry. At its introduction, it was a true gamechanger: a flexible, lightweight pipe on a roll, with no need for welding or soldering. Thanks to its strong, shape-retaining aluminium core, Henco immediately offered a solution that convinced both installers and end users.
Yet even today, several misconceptions about synthetic piping systems still persist—misconceptions that do not hold up against Henco’s proven quality and performance.
Misconception 1: Synthetic materials are less strong
Henco’s multilayer pipe (PE-Xc) features an aluminium core surrounded by physically cross-linked synthetic material (using the C-method), in which polyethylene chains are strengthened through electron irradiation. This ensures that Henco multilayer pipes can withstand demanding conditions without compromising integrity. The seamlessly butt-welded aluminium core combined with synthetic layers offers many advantages: Henco multilayer pipes can withstand high pressure, even over long periods (+50 years).
The aluminium core increases the pipe’s mechanical strength:
When bent, the pipe retains its shape and does not spring back.
Flattening of the pipe is a thing of the past.
Due to its rigidity, the pipe is ideal for visible installations.
Misconception 2: Synthetic materials are less durable
The electron irradiation used for physical cross-linking at Henco is a high-tech and clean process that does not involve added chemicals. This eliminates the need for flushing on-site. Throughout their entire 50-year lifespan, the pipes retain their properties, even in the most demanding environments.
Henco multilayer pipes are highly resistant to corrosion and chemical degradation.
Longer lifespan and reduced maintenance needs result in more stable water quality and lower system maintenance costs.
Certified in 80 countries.
Misconception 3: Synthetic materials are less suitable for hot and cold water
Synthetic materials are often considered less suitable for fluctuating temperatures. This can indeed be the case with standard pipes without an aluminium core.
However, the aluminium layer in Henco multilayer pipes provides:
A smooth inner surface that reduces the risk of biofilm formation
A low linear expansion coefficient comparable to copper or steel during temperature fluctuations
The unique structure, combining an aluminium core and physically cross-linked synthetic material, ensures the pipes remain dimensionally stable under temperature fluctuations (up to 95°C).
Misconception 4: Synthetic materials and legionella formation
Safe drinking water primarily depends on proper system design and dimensioning, including flow, temperature control, and water renewal. Material choice also plays a role. Henco multilayer pipes do not contain plasticizers (such as those found in PVC shower hoses) that can promote biofilm and legionella growth. On the contrary, the non-porous inner layer offers significant benefits:
Bacteria cannot accumulate inside the pipe
The pipe is fully corrosion-resistant, preventing harmful particles from being released into the water—even after 50 years—thereby minimizing opportunities for legionella growth
Misconception 5: Synthetic materials are cheaper and therefore inferior
Synthetic piping systems are more affordable to purchase, but the real savings come from reduced maintenance costs. Since Henco multilayer pipes do not corrode or degrade due to chemical reactions, both installers and end users benefit from significant cost savings.
In conclusion, the innovative Henco multilayer pipe remains a strong choice for installers who prioritize durability, safety, and ease of installation. It offers guaranteed quality and reliability for 50 years. Misconceptions about synthetic piping systems are mainly based on outdated or incorrect information, whereas the Henco pipe—with its unmatched dimensional stability, resistance to pressure and temperature, corrosion resistance, and safe drinking water quality—remains both a pioneer and the benchmark in the market.
