Full Description

This report presents the experimental methods and findings of a research program of MPC entitled "Characterization and Monitoring of Cracking in Wet Service." The program was supported by the Refining Division of the American Petroleum Institute (API) and by The Materials Properties Council (MPC) and its Fitness-for-Service group-sponsored program.

The two main objectives of the program were to study the performance in wet H₂S of welded steel plate of various qualities and microstructures, and evaluate the effectiveness of NDE techniques to characterize and monitor the cracking. To accomplish these objectives, a series of large scale exposure tests were conducted with steel panels (referred to herein as "windows") containing welds and attachments welded into a fabricated steel vessel filled with a pressurized H₂S containing solution prepared in accordance with NACE Standard TM0177-90, Method A. Experiments were performed using windows comprised of conventional, low sulfur, ultra-low sulfur and advanced thermo-mechanically controlled processed (TMCP) steels per the ASTM A516-70 and A841 specifications using various weld fabrication methods.
