BuTech — qualification testing for subsea conditions
Haskel reports that BuTech subsea ball valves passed API 6A/17D qualification tests. The tests included operating cycles, simulated external pressure at depth and low-pressure verification after high-pressure exposure. This illustrates the importance of testing performance beyond the nominal pressure rating.
