Hello,
First time in this sub-forum, hopefully it's the right place for my question. I searched around, but couldn't find any direct answers.
I work at a pressure vessel fabrication shop, and we have a job where we will be receiving and installing a custom gate valve (purchased by our customer). The gate valve supplier will not be supplying the valve with any code stamping of any sort, and our customer is asking for help ensuring the equipment is properly certified.
For custom valves, what is the North American standard for design and fabrication (B16.34?)?
How are custom valves certified, and what stamping (if any) is required?
For reference, some of the design conditions are:
[ul]
[li]Valve style: Gate valve[/li]
[li]Location of installation: United States (not sure which state yet)[/li]
[li]Design pressure: 1900psi[/li]
[li]Design temperature: 300°F[/li]
[li]Materials: 316ss[/li]
[/ul]
Thank you,
Marty
