Gentlemen
I´m trying to implement a positive material identification program on existing old piping systems. Does anyone know if it is possible to sort between A53GrB, API5L X42 and A516Gr70 relying only on portable spectrometry?
Your input will be greatly appreciated
Thank you all
Thank you all for the input
to clarify issues. I´m trying to use and old gas separator as a liquid propane vessel in Argentina (here API std´s and RP´s are considered requirements). The original operating temp. is 50°F intended operating temp is -22°F. Actual calculation indicates that MDMT is...
Hi everyone
i need to rerate an old vessel for propane service at -22°F. I´ve checked fitness for purpose API579 Sec 3 and computed a MDMT of -55°F for ASME VIII UCG66.1.
Do I need to Xray the vessel again? or just hydrotest?
thank you in advance for your advice

Hi Dennis
I´ve solved a similar problem for a number of gas compressor stations. My experience suggest the next sequence of events:
1st. measure piping vibration and pulsation levels
2nd. measure dynamic strains
this would help to sort and troubleshoot most vibration issues.
If it turns...
