Current polymer pipes used for transportation of natural gas at pressures under 0.4 MPa have sufficient strength to carry hydrogen, and diffusion losses arising mainly from pipe connectors have been estimated at three times higher for hydrogen than for natural gas (Sorensen et al, 2001). Transmission of natural gas at pressures up to 8 MPa uses steel pipes with welded connections. Most metals can develop brittleness after absorption of...

The pressure containment capability of the clamp, comprising both short- and long-term (survival) performance, at room temperature (of approximately 20 °C), 65 °C and 80 °C is summarized in Table 12.1 (Djukic et al., 2014b, 2015). The intermediate temperature of 65 °C is used in accordance with the requirements of ISO 14692-2 (2002), which is a standard for glass fibre-reinforced polymer pipes used in the O G industry.
