• Two-piece devices
• Battery lasted only few hours
• Single element-sequential
• Several minutes testing per sample
• Primarily high alloy
• Temperature and environmental conditions affect performance and reliability
First generation alloy analyzer, the TN 9200,
1960s
10
• Since late 1960s, XRF has evolved through 7 generations; each generation has added new capabilities
• Smaller
• Faster
• Better performance
• Easier to use
• Today, nearly all alloys can be tested with these powerful tools

In response to increasing industry safety demands, Analytical Training Consultants has produced the API Certification PMI Training Course
Guidelines and Application Procedures for API-RP 578 Using XRF and OES Technologies
23
• Purpose of the Course• To certify and re-certify (every 3 years) API 570 inspectors and
designated key personnel in understanding and applying API RP 578 in the proper Use and Application of procedures for utilizing XRF and OES technologies for PMI.
• 2 one-day sessions• Classroom instruction on API RP 578 guidelines• Hands-on PMI field testing procedures.• Understanding of API RP 578 Guidelines• Application of proper XRF and OES PMI testing procedures
Introduction
In today's risk-based QC environment, the need for positive material identification (PMI) has grown dramatically in refinery and petrochemical plant operations, requiring 100% alloy material verification for designated critical components.
24
• Priority for API 578 2nd Edition:
Inspection Program for HF ALKY Field Tests-API RP-571
25
• Priority for API 578 2nd Edition:• Residual Elements in Carbon Steels in Hydrofluoric Acid
Alkylation Units: Note: Carbon Steels in HF Acid service have been reported to suffer increased corrosion rates based on the Residual Elements (RE) in steels.
• In general, it has been reported that steels with a high RE content are likely to suffer enhanced corrosion attack. Operators should review the potential impact of this in HF service.
• A guideline is that for base metal of C> 0.18% wt% and Cu + Ni + Cr, C> 0.18% wt% and Cu + Ni + Cr, 0.15% wt % is optimum0.15% wt % is optimum. These values are critical as the type and concentrations to be measured will directly affect the analytical methods operations need to adopt.

Priority for API RP 578 2nd Edition
• Residual Elements in Carbon Steels in Hydrofluoric Acid Alkylation Units• Steels with a high RE content are likely to suffer enhanced corrosion attack.
• Optimal RE content guidelines:
C> 0.18 wt%
And
Cu + Ni + Cr < 0.20 wt %
• Sample preparation is very important:• Al Oxide disc used with a right angle grinder (<10 sec)
• approx. 0.004” removed

Priority for API RP 578 2nd Edition
• Process Units Susceptible to Sulfidation: • Carbon Steels with low silicon (0.10%) content can corrode at an accelerated rate • Assets at risk from this type of degradation should apply PMI control to determine
Silicon levels. • See API 571 and API RP 939-C

runs from the Furnace to the Reactor. • In 2003 during a PMI and UT inspection of all chrome circuits in the unit a small section of
10” 5CR pipe approximately 9” in length was found in the 9CR circuit. Thickness Thickness measurements of the 5CR showed severe thinning; approximate wall thickness remaining measurements of the 5CR showed severe thinning; approximate wall thickness remaining was .04”. was .04”.
