Acoustic Emission

Bulk O2 tanks


Use Acoustic Emission (AE) testing to inspect your pressure vessels in-service.  Detect fatigue cracks, corrosion fatigue cracks, stress corrosion cracking and other in-service related flaws.  These inspections are used to support American Petroleum Institute (API) in-service pressure vessel and above ground storage tank inspections as well as new vessels fabricated in accordance with American Society for Mechanical Engineers (ASME) boiler and pressure vessel code.


All vessels are pressurized to 105% or 110% of their maximum allowable working pressure (MAWP) with water, another liquid, or gas, most commonly nitrogen.  TKS is qualified by the U.S. Department of Transportation to recertify DOT cylinders.  Our expertise extends to:


  • ISO containers

  • Composite pressure vessels

  • Horizontal receivers

  • Spherical tanks

  • Self-contained breathing apparatus (SCBA) cylinders

  • NGV tanks

  • Above ground storage tanks

  • API 510 inspections

  • API 653 inspections
