Re: [MW:32323] PMI for ASTM A105 Flanges

Hi Babur,

https://www.intertek.com/non-destructive-testing/materials-testing/positive-material-identification-pmi/#:~:text=The%20device%20scans%20the%20metal,of%20pure%20carbon%20steel%20materials 

Positive material identification is performed using either of the two techniques below:

• X-ray Fluorescence (XRF) analyser: This is the most common method and the portability of the hand-held equipment allows Intertek to perform PMI on-site at our customers' premises. The device scans the metal material and identifies its key elements. However, it cannot detect carbon and some lighter elements and is not suitable for identification of pure carbon steel materials.
• Optical Emission Spectroscopy (OES): This method can detect almost all types of elements including carbon and lighter elements and carbon steel. Although not as portable as XRF analysers, the equipment can be transported to sites and used at high elevations with proper lifting arrangements.

Dear Experts,
One of our contractor purposed PMI for ASTM A105 Flanges due to lake of inspection documents.
As my understanding PMI is suitable for HSLAS,
SS and DSS. For carbon Steel we can check if there is something happened im change of welding consumables for welding.
Please share your experience.
