code for boring (machining) fittings from a sch to a sch ?
(OP)
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) ?

A plate (say A105) with a tappered bore (1/2") is to be installed between a pair of flanges.
The logical thing is to use a plate with a thickness per ASME B16.36 (orifice flanges) for the corresponding flange pressure class. And then make the bore to the required size.
Is there any reference to use for the calculations of the thickness?
