PMI Test on Sedelon Valves
Positive Material Identification (PMI) is the analysis of a metallic alloy to establish composition by reading the percentage quantities of its constituent elements. The object of this nondestructive testing method is to identify metal alloys in place using a portable X-Ray fluorescent analyzer that determines the elemental composition of the material.
At Sedelon, we have our own hand held Positive Material Analyser for confirming all stainless steel grades, Inconels, Hastelloys, Duplexes Steels and much more, without having to transport, alter, or damage the material.
For Duplex Stainless Steel and Stainless Steel valves, PMI is conducted by using PMI XRF portable test gun, pointed at the external surface of completed valves.
Parts of valves to be PMI tested are:
a)Body,
b)Bonnet,
c)Stem, (for all valves having externally-exposed stems)
By using PMI test, we can confirm all material received against orders raised by clients, and all tests can be witnessed by clients or their nominated inspectors.
