All rights reserved. 03.01.2019 A gas leak caused a small but intense fire in a large petrochemical facility where Grayloc ® connectors were used throughout the system. During the post-incident inspection, it was established that the connectors maintained their sealing integrity despite exposure to extremely high temperatures estimated at between 2,000°F and 3,000°F (1,090°C and 1,650°C). The gas leak, traced to an external packing gland, occurred in the hydrogen processing unit, which contained 80% hydrogen gas operating at 6,000 psi (414 bar) and 500°F (260°C). At this pressure and temperature, hydrogen gas will auto-ignite when exposed to atmospheric conditions. Gr
