Hi all,

I currently came across on a requirement of 'steam jacketted check valve' on a hydrocarbon line. The intent is to minimize the salt deposition on the line. We are supposed to SHELL DEP v30 as the standard which inturn not clearly defined any material specification steam jacketted valve by its MESC code.
We defined the design parameters and its material suitable for the service in the datasheet and submitted the same for vendor's query.

Now the valve vendor is asking for the requirement as 'Full jacketted' or 'half jacketted'??

Can anyone please explain the terminology of 'full or half steam jacketting' check valve and suggest the suitability to work in a hydrocarbon service?

Thanks in advance

Deepak

Depend on how critical is the issue you have to choose between the full and partialy jacketed.
