Can we use API 5L X42 pipe in plant piping with A234 Gr.WPB fittings and A105 flanges

[SMechanica]

Recently on reviewing a piping specification, I have found that the pipe use for plant piping is API-5L X42 with fittings of A234 Gr WPB and A-105 flanges. My question is that can we use API 5L X42 pipe in plant piping with A234 Gr.WPB fittings and A105 flanges? because API-5L X42 have higher yield strength as compared to A234 GrWPB material.

review your
A) contract
B) design code
your answer is in there.
dont forget to check weldability

if there's no requirement arising from your contract (e.g. pipe specifications), and the piping code 'allows' it, then it may be a yes.
oh, and dont forget sound engineering practice!
