With the latest generation of polyethylene grades having a raised resistance to slow crack growth (PE 100-RC), there is a high demand for suitable test methods. Ernst van der Stok of Kiwa presents developments related to two pipe tests for PE 100-RC. The first is the point load test (PLT), for which improvements to the test equipment and the current status of an international study are described. The second is the accelerated notch pipe test (aNPT), for which an eco-friendly version is presented. To minimize the required detergent quantities, the test uses smaller containers for each pipe, rather than a large bath.
This is a pre-recorded presentation for the XXth International Plastic Pipes Conference and Exhibition held in Amsterdam, the Netherlands for September 6 – 8, 2021.
Almost 70.000 km of PVC (rigid PVC (PVC-U) and impact modified PVC (PVC-HI)) pipes are currently in use for the distribution of natural gas in the Netherlands, which accounts for 64% of the low pressure gas grid (up to 8 bar). Sjoerd Jansma of Kiwa presents the developments regarding two non-destructive tests for PVC pipes.
