Subsea valves
From Wikipedia, the free encyclopedia
Subsea valves are used to isolate or control the flow of material through an undersea pipeline (submarine pipeline) or other apparatus. Most commonly used to transport oil and gas, they are designed to function in a sub-marine environment, withstanding the effects of raised external pressure, salt-water corrosion, and bubbles or debris in the material carried. Subsea valves undergo stringent testing to ensure high reliability.
Subsea valves are used in sub-marine environments, which can range in depth from shallow water (usually down to a depth of 75 meters) to deep water (down to 3500 meters).[1] Various industries use subsea valves, with the oil and gas sector accounting for the majority, where there is a need to move material from, to, or below the seabed.
