ASME Section IX P3 to P3 WPS

[malever]

Good afternoon,

I have been tasked with writing a P3 to P3 WPS, but have absolutely no experience with writing WPS' and very little experience with P3 piping.
Any tips on where to look or what to reference to ensure that WPS is filled out properly would be greatly appreciated. I don't want it to be rejected.

Thank you in advance for your assistance
