Hello,

New member, glad to join this community!

Need some help here, does anyone know what a " Turning a Blind " is in piping? I've tried googleling it but I can't find it specificaly.

I'm new at my job and I'm trying to learn the terms.

Thanks for the help in advance!

Sounds like a reference to a spectacle (figure 8) blind. You can see the image below.

Spectacle blinds have an open and a closed side. They are connected by a short little bridge piece between them. The bridge has a bolt hole in the middle so that the blind may be bolted between two flanges.
They are used to quickly isolate a piping system for maintenance by simply loosening the bolts and turning the the blind from the open side to the closed side.

That's my initial guess.

It always helps us to understand what your job is, what industry, design or operations, Any sort of context really.

But I think the post above is what is meant.

Luis Oliveira,
Do you have any trained and experienced Pipers in your Company?
In general terms where is your Company located?


Sometimes its possible to do all the right things and still get bad results

Yes, we have very experienced people here, but that particular term in English that they haven't heard it before.

Based on their experience they had a pretty good guess what it was, like the gentelman above answered they thought it was that too, but I just wanted to be 100% sure since Im very new to the subject.

We are located in Portugal, and we also work internationally.

There is also the term, "swinging the blind" but you all knew that.

ASME 16.48 refers to this issue.
