#ndt The stainless steel pipes commonly used on offshore platforms are susceptible to corrosion and must be regularly inspected. For decades, radiography was the primary method used to detect corrosion in these pipes, but as regulations governing the use of X-rays continue to tighten, radiographic testing (RT) is no longer permitted in some countries.

Eddy current is an excellent alternative to detect and evaluate corrosion pitting depth in the 300 series stainless steel commonly used on offshore platforms.
