How to calculate Pipe/Fitting Wall thickness as per ASME B16.9
How to calculate Pipe/Fitting Wall thickness as per ASME B16.9
(OP)
Hi,
I am a Mechanical Engineer presently working on Piping Specifications. This is a new field for me as a result, I got to do a lot of reference through books and online.
The piping Specification I am working on shows a list of Pipe fittings e.g. Elbow Long Radius, Tee, Reducing Tee, Concentric Tee etc. It says from sizes 2"-36", Wall thickness/Class as per ASME B16.9
How do I calculate the Wall thickness or find out the Class?
Material - CU/NI 90/10(UNS C7060X) EEMUA 146
End Connection- Butt weld
Hoping to hear from you soon.
Thanks & Regards

In order to specify the pipe fittings as per ASME B16.9, you need to know the following (atleast)
- Material of construction ( ASTM or equivalent grade)
- nominal size NB
- schedule
If I understand your problem correctly, you do not know the schedule of the pipe fittings. In that case, it would not be wrong to use the fittings having the same schedule as that of the corresponding PIPES where these fittings are going to be used. ( I presume, the "Pipe" specification available with you, has the 'schedule' metioned in the specification)
Another option is to actually calculate the wall thickness as mentioned by "B16.9 answer" and select the suitable 'schedule'.
Hope this helps.
