Dear All

I am working on Brown field projects. Client has extra material like angular choke valves @ there store. Can anyone guide me that

can angular chokes be used instead of inline chokes? Please share your experiences.

A choke valve works as a throttle valve whichever is the style or the type.  That has been my experience in using them in the field.


I have preferred the 90 degree type, but that has been because of the piping configuration and the applications.


Do you have any doubts or problems in deciding which style to use?  How do you intend to use the Choke valve?  And in what kind of service?


You fail in giving us the raw, basic data to respond specifically.  Do you understand that you could use the valve as a simple throttle device on a single phase fluid or as an adiabatic expansion of 2- or 3-phase fluid?  Or even as a Joule-Thomson valve?  If you do understand that and know how the valve is built, why don't you tell us how you intend to use it and on what type and condition of fluid?  That would make things so simple ........  But maybe you are working on a super-secret government project and can't reveal such simple data.


And, by the way, a choke valve is not a relief device.  That is why I'm moving this thread out of the Relief Devices Forum.

The system in which we use inline choke is gas lift line and water injection line. Because of the extra stock of angular choke I raise the question.
