The coefficient of expansionamounts to 0.025mm/mK.Corrosion-resistantThe smooth surface of the pipeprevents build-up of scale orother debris. This means sedimentation andcorrosion are avoided. The smoothnessof the inner pipe also ensures a minimumpressure loss.Shape-retainingAfter bending, the pipe retainsthe required shape. It has nothermal memory such as other syntheticpipes. This simplifies and accelerates theinstallation of the pipe and can reduce theamount of fittings required.Wear-resistantThe outer and inner pipe aremade of electron beam crosslinkedpolyethylene. As a result, the pipeis not subject to wear, even at hightemperatures and flow speeds.Fully oxygen- and watervapour-proof (diffusion)The integrated aluminium layerprevents the penetration of oxygen in thepipe. This means corrosion problems withany metal components in the installationare avoided.Low weight (fast andsimple assembly)Fast and simple installation savestime and money. The Henco pipe is flexible andextremely light. A coil of 200m standard16mm x 2mm pipe weighs a mere 25kg.Long lifeIf the pipe is used according tothe specified working pressure andtemperature, a projected working life of atleast 50 years maybe achieved.No noise nuisanceAs distinct from metal pipes, nonoise nuisance originates dueto the liquid flow if the pipe diameter iscorrectly selected. Contact noises can beavoided by correct assembly.From drinking water tochemical liquidsThe pipe complies with themost stringent toxicological and hygienicrequirements. It is 100% suitable fortransporting drinking water. The pipe isalso resistant to various chemical liquids.1 Range overview 2 Product details 3 Technical data 4 Installation instructions 35
