The Idea of not using threaded connection in any specification / class is to avoid taking any chance or because the class is for some critical service or for high pressure. But using threaded connection after block valve reduces the severity of that pipe and hence a threaded connection can be used.

Thank you very much, Bruce.
My concern is that: wouldnt that threaded instrument
connection make the line threaded one?
How should we explain the case?
Hope you understand my query.
