Sjoerd Jansma about NDT on PVC (Presentation PPXX)

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.
