Home > Service Series > Testing > NDT > Time-of-Flight Diffraction Testing(TOFD)

Application Scope

Quantification of weld defects in pipelines and storage tanks
Monitoring of active defects in in - service equipment, such as the assessment of stress corrosion cracking (SCC) propagation and the tracking of fatigue crack heights
Testing of special materials and complex structures, such as austenitic stainless steel welds, dissimilar steel welded joints, and small - curvature pipe fittings (elbows)

Technical Features

TOFD serves as a "ruler" for the quantitative analysis of weld cracks in the oil and gas field.
