TESTING SPOOLABLE REINFORCED FLEXIBLE PIPES AND LINER MATERIAL FOR HIGH-PRESSURE HYDROGEN TRANSPORT

 

Sjoerd Jansma, Peter Cloos, Ernst van der Stok

# 2021 Amsterdam

This paper describes two different test methods used to determine the permeation rate of hydrogen through a reinforced thermoplastic pipe (RTP) system with a HDPE liner pipe and a gas-tight layer at a pressure of 42 bar(g) hydrogen and ambient temperature. One method involThe results of the aforementioned tests have been combined with existing certifications, which has led to a covenant between the certification agency and producer. Based on this covenant, the actual application of RTP as the backbone of a hydrogen gas network in the northern Netherlands will be established.ved combining the permeation resistance of each individual layer, while the other involved determining the permeation rate of the entire pipe (with an outside diameter of 150 mm), including the inline couplers and end fittings. The two permeation rates obtained for the pipe correspond very well, and are extremely small in comparison to the permeation of hydrogen through a solid wall PE pipe.

This paper also describes the chemical resistance check, which confirms that the piping materials are suitable for the intended application. In this test, the individual pipe materials were immersed in a 42 bar(g) hydrogen environment for 95 days, after which no significant change in mechanical properties, weight or volume were observed.

The results of the aforementioned tests have been combined with existing certifications, which has led to a covenant between the certification agency and producer. Based on this covenant, the actual application of RTP as the backbone of a hydrogen gas network in the northern Netherlands will be established.
