Weldolet Vs threadolet 1

[ashwani25]

I need to understand when to use a weldolet connection vs threadolet on any pressure class piping ( ANSI 150, 600, 900, 1500).

So far I know that weldolets tend to have less stress concentrations than threadolets , but the question that's bugging me is why use threadolet if weldolets are so damn good.

You need to get more familiar with the wordings. On both, all depend on the design er, owner and economy.

Any "olet" is a proprietary name connected to Bonney Forge. "Reinforced branch fittings" is the more universal name.

you use a "weldolet" when you want to weld a pipe or fitting directly to the branch fitting and a "threadolet" when you want to screw the connecting pipe or fitting (e.g. valve) to the branch connection.

If you search here for welded vs threaded connection then you'll see a lot of different opinions on when one or the other is deemed a good idea, but generally your piping spec will tell you when you can use threaded connections (tends to be smaller bore, lower pressure)
