Hey moe,
Thanks for the useful 2 cents...
What do you say about test blinds made of flat plate and welded to the pipe directly with a groove joint? Are they used frequently at sites?

you're welcome dear,
its not advisable actually it's not permitted to use test blinds as welded or bolted end closures

Can you provide any reference from some code / standard or specification?
Thanks in advance.
