Customer purchased a 12" Tee strainer with A234 WPB body.
We were just informed it will be butt welded into a pipeline with API 5L X52 pipe.
What are the issues with compatibility and welding?
Design Pressure/Temperature is 1040 psig @ -20 to 150 Degrees F, within the operating range of the Class 600 flange and of the Sch 80 fitting, based on ASME B31.3.
However, the high yield pipe uses a lower schedule - Sch 40, using B31.8 design rules (by others).
I believe they will to have a qualified weld procedure due to material differences.
Weld prep per B31.8 Appendix I.
I don't know what other requirements may be applicable.
