Is there a code for this. We have a WPB B16.9 16" 90` Elbows which have been bored from sch 80 to sch 40.
The angel of the taper bore is 39, which in my opinion is to great for the flow.
A colleague think that the angle of the taper bore shall be 17,5 and another think there is a relations between the wall thickness which is 1:4.
But no one knows where to find these information, they just know it...
Is this covered in any standard (norm) ?
