A pancaked valve
A pancaked valve
(OP)
Hi everybody.
I am not an engineer of any kind but only an humble translator who specializes on engineering matters (the petroleum industry to be more specific).
I have come across a word which has me baffled completely.
What does it mean to pancake a valve for isolation purposes when Hydrotesting? I have found out that there is something called a “pancake blank”, so to pancake a valve does it mean to install a pancake blank? And what is it? What is the difference between a pancake blank and a blind flange, for example?
Thank you.

RE: A pancaked valve
The word 'pancake', as in 'round' suggests that it might be a paddle blank without the paddle, which sounds like a potentially dangerous thing to install in a pipe.
Or, maybe the food reference is to be taken more literally, i.e., it's a round blank that's intended to be temporary, and intended to be destroyed by the eventual process fluid, saving the cost of physical removal. What brought that to mind was my Dad's practice of stuffing bread into the end of water lines to make them solderable without draining the system. Restored pressure flushed the soggy bread right out.
But I've never heard of a "pancake blank" in four decades of screwing around with pipe, outside the petroleum industry. Maybe it's common knowledge in the oil patch; I wouldn't know. Sorry.

Your guess may be right.
This is definitely NOT a commonly used term even in the oil industry as I have only found a very few citation in the net and as you said without definition.
Now, taking for good your explanation about a “thin blank…” I only have to find a shorter way to put it into Spanish … not as easy as it sounds.
Thanks again!!

So if I understand you right a pancake blank is practically the same as a skillet blind.
Am I correct?

I suppose it is no mere coincidence that pancakes are made in a skillet.
Sorry, couldn't resist..........

If you ever need any Spanish terminology or linguistic clarification (God forbid) just put a posting (I’ll be looking) or I think you can mail me trough the site.
I have been looking for this term ALL day, so I am really thankful.
Bye

P.S. If you don’t mind I may be bothering you again with other terms in the future
RE: A pancaked valve
Might have come from flat as a pancake when valves were squashed flat when overtightened.
