The use of hydrogen gas is widely seen as a key component of the current energy transition. 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. Two different approaches were used to determine the permeation rate: 1) combining single layer permeation measurements, and 2) permeation measurements on the entire system.
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.
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.

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.
