TULA™ (TOFD Ultra Low Angle) is another ground breaking, patent pending innovation from GB inspection systems. The TULA™ allow the use of TOFD imaging in a single compact housing, compatible with B-Scan capable instruments. 

Designed with the detection of early stage High Temperature Hydrogen Attack (HTHA) in mind the TULA™ is an important part of the detection process and is featured in the HTHA course endorsed by all major oil companies and conducted by Lavender International.             

Key Points about TULA™     

  • Has been proven to be a very simple yet highly sensitive means of detecting HTHA
  • Is a complimentary technique to a number of others including PAUT, TFM & TOFD
  • TULA™ probes with specific focal depths are required to optimize detection throughout a range of thicknesses.
  • The TULA™ concept has also been applied to angle beam probes for the purpose of detecting HTHA in Weld HAZ regions.
