Positive material identification (PMI) is the analysis of a material, this can be any material but is generally used for the analysis of metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. Typical methods for PMI include X-ray fluorescence (XRF) and optical emission spectrometry (OES). [1]
Traceability and positive material identification (PMI) When the alloys for piping are forged, metallurgical tests are performed to determine material composition by % of each chemical element in the piping, and the results are recorded in a material test report, also known as a Mill Test Report (MTR).
AGA – American Gas Association. AGRU – acid gas removal unit. AGT – (1) agitator, used in drilling. AGT – (2) authorised gas tester (certified by OPITTO) AGT – (3) Azerbaijan – Georgia – Turkey (a region rich in oil related activity) [3] AHBDF – along hole (depth) below Derrick floor. AHD – along hole depth.
A mill test report ( MTR) and often also called a certified mill test report, certified material test report, mill test certificate (MTC), inspection certificate, certificate of test, or a host of other names, is a quality assurance document used in the metals industry that certifies a material's chemical and physical properties and states a ...
Moreover, test samples do not have to be prepared in any way, so, often, a piece of scrap is used. The main disadvantage to spark testing is its inability to identify a material positively; if positive identification is required, chemical analysis must be used. The spark comparison method also damages the material being tested, at least slightly.
They can only report test results. Normally they work following specific work instructions for testing procedures and rejection criteria. Level 2 are engineers or experienced technicians who are able to set up and calibrate testing equipment, conduct the inspection according to codes and standards (instead of following work instructions) and ...
The scale at the bottom is numbered in centimetres. Magnetic particle inspection ( MPI) is a nondestructive testing process where a magnetic field is used for detecting surface, and shallow subsurface, discontinuities in ferromagnetic materials. Examples of ferromagnetic materials include iron, nickel, cobalt, and some of their alloys.
The International Material Data System ( IMDS) is a global data repository that contains information on materials used by the automotive industry. Several leading auto manufacturers use the IMDS to maintain data for various reporting requirements. In the IMDS, all materials present in finished automobile manufacturing are collected, maintained ...
