Cryogenic valves for LNG application – Part 1

Cryogenic valves - LNG application.

One of our customers needed a primary isolation valve for a pressure measurement on a container ship. The ship uses natural gas power. The valve had to meet the Fire Safe API requirements. It also had to pass a cryogenic test with liquid nitrogen (-196 ° C). The container ship rides under the American flag. Thus, an independent examiner had to administer the test. This examiner came from the American Bureau of Shipping (ABS) and the US Coast Guard.
