Small Size Portable Universal NDT Indentation Tester for Petrochemical, Thermal Power
Products Description
Mechanical performance is an important basis for structural static strength design and integrityevaluation, and the core indicator to determine material failure and damage and reflect the safety level ofequipment operation, which makes it necessary to conduct mechanical performance testing.
However, traditional testing methods, such as tensile and impact testing, require destructive sampling andtesting in the laboratory. Not only s destructive sampling unacceptable, but there are also issues withcumbersome testing procedures and long testing cycles, so they cannot be used for performance testing ofin-service equipment or small structures, such as micro-areas of welded joints.
In response to this problem, Gurion developed a depth-sensing micro-indentation testing system，the portable universal NDT indentation tester consists of three parts:the indentation device, the control system, and the calculation software.
It records the displacement-loading data caused by the indenter of a specific shape intruding into thematerial to calculate the vield strength, tensile strength, stress-strain curve, residual stress, hardness andother mechanical performance parameters of the material. lt can not only test small non-uniform micro-areasbut is also suitable for the online test of engineering structures in complex on-site environments.
Comparecwith traditional mechanical performance testing methods:
(1) it is with higher efficiency and lower costs;
(2) The testing device is light, small and portable;
(3) The testing process will not cause damage to the equipment.

10. Can the testing point be so small to ensure the accuracy of the overall product's results? Is it possible that the result of one testing point is with different numerical value from the other points?
Accurate testing and measurement provide objective feedback on the mechanical performance indicators of metal materials.The characteristics of metal materials are consistent both on the surface and on the inside. By testing the surface mechanical properties, it is theoretically and academically traceable.If mechanical properties of metal materials on the surface change, its internal microstructure will also suffer similar deformation. -
