wall thickness of pipes
wall thickness of pipes
(OP)
Dear Sirs:
I just have a brief question in regard to the physical properties of pipes.
Is it possible to obtain the wall thickness of pipes by only knowing the piping class (for instance B3) and the ASME pressure class. I have not got information in regard to the pipe schedule. I just know the nominal diameter, and the pipe class and I need to get the wall thickness of some pipes.
Regards
Daniel

You will also need the design factor (.72, .6, .5), the design pressure, operating temperature, corrosion allowance (if any), joint factor, and pipe grade (SMYS).

RE: wall thickness of pipes
If you know the pressure class (e.g. 300 LB) then you could "over-design" and assume the highest pressure rating for that class at the highest temperature and assume a significant corrosion allowance and then determine the thicknesses for a range of materials. However I would ask for a project line list and determine the pipe thicknesses based on the information stated by GregLamberson above to achieve economic pipe schedules.

Don't get the impression that pipe design is based only on internal pressure stress and maximum material temperature rating.
