A need to establish guidelines for inspection of vessels and piping subject to wet H2S cracking is growing. Certainly there is no practical way to inspect the I.D. of most piping, except for UT, and this can be like looking for a needle in a haystack. Questions about what percentages of internal WFMP inspections should be performed are difficult to develop a standard rule of thumb for. Demands upon engineers from management to increase equipment safety and reliability while minimizing turnaround frequencies, produces quite a challenge.

A program to help answer these needs is presented. Use of Acoustic Emission, Automated ultrasonics, field metallography with replicas, flaw sizing and wet fluorescent magnetic particle inspection are discussed in detail.
