What are the special requirements for underwater valves?
Thread Content
Hello, everyone. I’ve recently come across a question regarding the selection of subsea valves. It’s my first time dealing with such valves, and since they are used in seawater environments, I’m wondering if there are any specific requirements for this type of valve, such as regard to materials, sealing, pressure, etc. Additionally, there are no relevant standards for subsea valves in China; I’m also curious about how selection is done abroad. Thank you all!
In particular, it is necessary to consider the impact of external pressure at the seabed on the valve; therefore, evaluation experiments must be conducted in a high-pressure chamber during the assessment process. There are also the requirements regarding corrosion resistance of seawater. Hope this can help you
