ESD bore type
ESD bore type
(OP)
During IP run on 6" gaslift line, BiDi pig got stuck at ESD valve. Pig was retrieved at launcher side, but would like to analyse why it got stuck. Probably to check bore type of ESD valve and downstream ball valve whether full bore or reduced bore, is radiography an efficient way? Or is there any other solution?

If the bore of the valve is less than the pipe ID then you may have to pull the ball and send it to a machine shop.

Take some general external measurements and check with manufacturers catalogue this will usually tell you whether you have FB or RB - but it does not mean that full bore is same ID as pipe

Have you checked the valve datasheet?
An alternative is to pull the valve and check it. This would involve shutting down your line (unless there is a bypass), and a field crew.
With regards to checking with the manufacturer, I don't think that will work. In my local area, the manufacturer would most likely not give an answer. The reasons are many, and it basically boils down to this - once it leave their shop, they can not control what happens to their product, and due to legal issues, will most likely not commit to anything without investigating it themselves (in this case, they would probably charge you to send a tech there to pull the valve and check the port).
