Brothers Inspection offering the following NDT (Non Destructive Testing) Services:- Positive Material Identification(PMI), Ultrasonic Testing, Radiograpy Testing, Magnetic Particle Testing , Dye Penetrant Testing and many more of Non Destructive testing available from Us. Although we support our client projects with many more NDT disciplines (see our list under Specialist manpower) these are the main NDT services offered independently on a project basis.
Positive Material Identification (PMI) provides alloy chemistry and grade ID information
instantly using a handheld tube-based analyzer without having to transport, alter, or
damage the material. PMI is also used to ensure that the parent material in vessels and pipe
spools is composed of the correct composition (i.e., 304 or 316L) and once the component is
welded that the correct filler material was used.
PMI verification is used to dedicate material or components that were purchased
"commercial grade" without having the extra cost associated with purchasing "safety
related" components and material. When used in combination with the receipt inspection
process, PMI also ensures that the base material of piping and vessels meets the design
specification and/or purchase order requirements.
When repairs are made to existing vessels and piping, a PMI test can quickly verify the
material composition to ensure that the correct welding procedures and consumables
are selected for use.
With Positive Material Identification (PMI) the alloy composition, and thus, the identity of
materials can be determined. If a material certificate is missing or/and you need to be certain
about the type of material used, PMI as an NDT method is the best solution. Positive Material
Identification is particularly used for high quality metals like stainless steel and high alloy metals.
