Our HDPE Fittings and Pipes are made from PE 100-RC (RC = resistance to cracks). The main technical advantage of PE 100-RC is that it is significantly more resistant to slow crack growth. This saves costs during installation, improves safety, and extends the service life of the entire piping system.
A complete range of injection moulded HDPE Fittings made of PE 100-RC is available. This includes HDPE Fittings for butt-fusion welding in long spigot and short-spigot version, as well and HDPE Fittings for electro-fusion welding.
In a comprehensive series of tests, the renowned HESSEL Ingenieurtechnik GmbH test institute impressively demonstrated that the service life of PE 100-RC electro-fusion couplers is many times longer than that of PE 100 electro-fusion couplers currently available on the market. The vertical axis shows the service life in an accelerated internal pressure test (90 °C, test pressure of 9.2 bar and wetting agent 2% NM5 in deionised water). The horizontal axis shows the correlating service life of corresponding test specimens in a full-notch creep test (FNCT), which were also subjected to accelerated test conditions.
The results of these tests proof a service life of up to ten times longer for PE 100-RC electro-socket fittings under identical test conditions!
The full-notch creep test (FNCT as per ISO 16770) is a recognised test method for determining resistance to slow crack growth in polyethylene. After a wetting agent has been applied, a notched test specimen is exposed to tensile stress at a high temperature (80 °C). The minimum service life for PE 100-RC fittings must be > 8760 hours acc. to PAS 1075. In contrast to this, the required minimum service life for PE 100 components acc. to DVS 2205-1 is just 300 hours. The excellent quality and operating safety of AGRULINE fittings has now been substantially improved once again through the new PE 100-RC.
