Power Plants

Always Ongoing

Aztech is employed by the regions many power plant and examines the various requested materials for the presence of internal discontinuities, induced discontinuities (such as welds), and time-dependent degradation, such as corrosion, cracking and environmental damage.

Aztech’s power plant inspections are performed to the ASME boiler pressure vessel code B31.1 and section 5 or Aztech’s customer specification. Aztech uses the following methods for its power plan customers;

  • Magnetic particle- fluorescent & dry powder.
  • Liquid penetrant- visible and fluorescent.
  • Radiography- iridium 192 source (2)
  • Positive material identification (PMI)
  • Ultrasonic testing-thickness and shear wave.
  • Visual inspection (VT)
  • Hardness testing- Brinell & Rockwell
  • Welder performance qualification (WPQ) testing

Aztech’s NDT services provides the following advantages:

  • Can easily locate internal structural discontinuities using visual comparison with known geometric features of the test object.
  • Is applicable to most classes of materials.
  • Is considered by many to be the most universal approach to volumetric examination.
  • Yields a visual rendition of internal voids and fabrication errors that is readily interpretable.
  • Provides a permanent record of the inspection, including evidence of the sensitivity of the test when image quality indicators (IQs) are used.
