When Henco introduced its multilayer pipe about 30 years ago, it was a groundbreaking innovation. Installers were thrilled: a flexible pipe, conveniently available on rolls, feather-light, and no need for welding or soldering. Extremely durable and dimensionally stable, thanks to its aluminum core. Yet, misconceptions or prejudices about plastic pipes still persist. Here are 5 common myths, along with 5 reasons why the Henco multilayer pipe has become the market standard.

Misconception 1: synthetic is less strong

Henco’s multilayer pipe (PE-Xc) features an aluminum core encased by physically cross-linked plastic, where polyethylene chains are strengthened by electron beam irradiation. This ensures that Henco multilayer pipes withstand challenging conditions without losing integrity. The seamless butt-welded aluminum core, combined with the synthetic layers, makes these pipes resistant to high pressure, even during prolonged use. This durability makes Henco’s multilayer pipe ideal for pressure-sensitive installations, such as in hospitals and care facilities, where constant pressure and continuity are critical.

Misconception 2: synthetic is less sustainable

Henco employs electron beam cross-linking, a high-tech and clean process that uses no chemical additives. Throughout their lifespan, the pipes retain their properties even in the most demanding environments, as certified in 80 countries worldwide. The synthetic layers in the multilayer pipe resist corrosion and chemical degradation, extending the lifespan and reducing maintenance needs. This results not only in more stable water quality but also in lower maintenance costs.

Misconception 3: synthetic is unsuitable for hot and cold water

synthetic is often deemed less suitable for fluctuating temperatures. While this may apply to standard synthetic pipes without an aluminum core, Henco’s multilayer pipes are different. The aluminum core not only increases pressure resistance but also ensures a low linear expansion coefficient, comparable to copper or steel, during temperature fluctuations. Thanks to its unique structure of an aluminum core with physically cross-linked synthetic , the pipes remain dimensionally stable under temperature changes (up to 95°C) without material degradation, expansion, or deformation.

Misconception 4: synthetic and legionella formation

Safe drinking water primarily depends on a well-designed system, including flow, temperature control, and water renewal. Material choice also plays a role. Henco’s multilayer pipes contain no plasticizers (such as those found in PVC shower hoses) that could promote biofilm or legionella growth. On the contrary, the non-porous inner layer of the Henco multilayer pipe prevents bacterial buildup. Additionally, the physical cross-linking of PE-Xc pipes eliminates the risk of chemical residues. Independent research shows that multilayer pipes achieve lower BFP (biofilm potential) values and lower bacterial counts than copper or stainless steel after several months*. Furthermore, the multilayer pipe is entirely corrosion-resistant, ensuring no harmful particles are released into the water, even after 50 years. Legionella is therefore no more likely to develop in synthetic pipes than in other materials.

Misconception 5: synthetic is cheaper, and therefore inferior

Not all synthetics are created equal. Henco’s multilayer pipes, with their 5-layer construction, leave nothing to chance. While synthetic pipes are more affordable upfront, they are also less affected by fluctuating raw material prices. Additionally, they excel in terms of maintenance costs, as they do not corrode or suffer from chemical degradation.

The ease of installation with plastic pipes is a game-changer: the flexibility of the multilayer pipe ensures smooth and comfortable installation, even in complex building structures. This saves time, reduces the number of connections (and potential weak points), and contributes to lower installation and maintenance costs, as well as a longer lifespan.

In conclusion

Multilayer synthetic pipes, especially the innovative Henco multilayer pipe, remain a top choice for installers who prioritize durability, safety, and ease of installation. Guaranteed quality and reliability for 50 years. Misconceptions about synthetic pipes often stem from outdated or incorrect information. With unmatched shape stability, resistance to pressure and temperature, corrosion resistance, and safe drinking water quality, the Henco pipe continues to be a pioneer and the market’s leading reference.
