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. The first is the Leeb hardness test , the second is the photo spectroscopic analysis of both the inside and outside of the pipe. Both tests are compared to the piping materials ductility determined with the tensile impact test, currently used to determine the quality of the PVC piping materials.
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.
Sjoerd Jansma of Kiwa presents the high-pressure hydrogen permeation testing of a spoolable reinforced thermoplastic pipe (RTP, also known as Thermoplastic Composite Pipes (TCP) or Flexible Composite Pipes) system and the testing of the chemical resistance to hydrogen of the piping materials.

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.
