Crosslinking the polymer in this way increasesits resistance to loads generated by internalpressure and high temperatures. A furtherexplanation of cross linking and the electronbeam method can be found later in this guide.A continuous longitudinal butt welded jointis used to form the aluminium into a tubularreinforcing layer. This type of weld ensuresan even wall thickness distribution, not onlyin the aluminium, but in all the layers aroundthe pipe circumference. As a result, pressingloads are also evenly distributed which in turnprovides a consistent sealing condition in thepressed joint.The different layers are bonded to each otherusing a high quality adhesive. The result is amultilayer pipe with the flexibility of apolymer combined with temperature andpressure performance associated with metals.The aluminium layer not only gives themultilayer pipe high temperature and pressureperformance and shape retaining properties,it also provides a guaranteed oxygen barrier.The pipe meets the requirements of thestrictest standards for drinking waterinstallations and is resistant to aggressivesubstances.Inner pipe of electron beamcross-linked polyethylene(PE-Xc), extruded fromhigh density polyethylenemoleculesHigh quality adhesivelayer for a homogenousconnection between thealuminium layer and thePE-Xc inner pipeAluminium layer(AL), longitudinallyseamlessly weldedand controlledHigh quality adhesivelayer for a homogenousconnection between thealuminium layer and thePE-Xc outer pipeOuter pipe of electron beamcross-linked polyethylene (PE-Xc), extruded from high densitypolyethylene molecules1 Range overview 2 Product details 3 Technical data 4 Installation instructions 33
