26 Standard pipes Standard pipes Pipe system made of PE100 RC Extena standard pipe systems are manufactured from PE100 RC, which is considered to be the safest raw material with the best conditions for maximum service life. The pipes are suitable for both laying in trenches and alternative installation methods. If you want extra protection for the pipe, we recommend Extena SLM 3.0, a pipe that also has a protective sheath. PE100 RC PE100 RC is polymerized with hexene instead of butene, which is often used for traditional PE. Hexene is an alkene with long molecules, which strengthen the bond in a molecular chain. The bonding molecules make the RC material stronger, but above all it retains the structure of the crystalline regions. The PE polymer is thus designed for maximum mechanical resistance to slow crack growth (SCG) and, in accordance with PAS 1075, the RC material has 17 times higher requirements for resistance to slow crack growth. Since slow crack growth is one of the most common causes of pressure pipe fracture, a high resistance to this type of damage is crucial for the service life of the pipe system. Furthermore, a high resistance to crack growth makes alternative installation methods faster, more cost effective and safer, as scratches can easily occur when this method of pipelaying is used. Stripes or colouration The standard pipes are supplied in two designs. Either with stripes or with approx. 10% of the pipe’s wall thickness (outer layer) in a different colour to allow you to locate and assess any scratches that have occurred during pipelaying. According to AMA, scratches and external damage to PE pipes may not exceed 10% of the pipe´s wall thickness. With our colour layer, which makes up approx. 10% of the pipe’s wall thickness, you can easily see if a scratch is deeper than approx. 10%. Homogeneous pipes All our standard pipes are homogeneous, i.e. they do not have a layer that needs to be stripped prior to jointing. The coloured pipe has a different colouration makes up approx. 10% of the pipe’s wall thickness and is integrated homogeneously with the main pipe. The RC material combined with the coloured outer layer and our tight tolerances in terms of ovality provide a great pipe that makes pipelaying more efficient and creates safe and secure pipe systems. Standard pipe made of PE100 RC. Available in dim ø 16-1600 mm.
