This volume examines more than 100 cases of failure and the process by which they were analyzed, diagnosed, and resolved. It provides expert analysis and insight on a variety of materials, failure modes, root causes, and analytical techniques. Included are sections dedicated to specific components, industries, and other factors in transportation an...

Leak or rupture of carbon steel line pipe caused by hydrogen-assisted cracking (HAC) in near-ambient temperature of wet sour hydrocarbon services could lead to catastrophic consequences ranging from loss of lives to a heavy financial impact. This chapter discusses practical techniques that should be implemented during the plate/coil and pipe manufa...

Hydrogen assisted cracking (HAC) could lead to catastrophic failures in oil and gas industry piping and pressurized equipment with consequences ranging from heavy financial impact to fatality. Wet sour hydrocarbon services could lead to catastrophic consequences ranging from loss of lives to a heavy financial impact. This paper provides effective m...

This article discusses two failures experienced in spiral-welded pipeline/piping due to stress-oriented hydrogen-induced cracking (SOHIC). The first identified SOHIC failure occurred in 1974, before the term SOHIC was coined. A second failure occurred in 1998 in the piping system handling aggressive sour natural gas liquid (NGL) service. The condit...

Welded pipes ordered for wet sour service are required to be manufactured from hydrogen-induced cracking (HIC) resistant steel plates. Pipe manufacturers procure steel plates with HIC testing, and other additional requirements with respect to chemistry, mechanical testing, and non-destructive testing (NDT) to meet client requirements. There have be...

Hydrogen Induced Cracking (HIC) and Stress Oriented Hydrogen Induced Cracking (SOHIC) tests were conducted on a conventional ASTM A516-70 pressure vessel steel exposed to H2S- containing diglycolamine (DGA) gas-sweetening environments. Baseline HIC and SOHIC tests were conducted in NACE TM0284-96 solution A. For the SOHIC tests, four-point double b...

A spiral welded pipeline failure that occurred during hydrotest was attributed to transit fatigue, caused during highway transportation. Transit fatigue during rail, road and marine transportation is a well-known failure mechanism. American Petroleum Institute (API) standards for prevention of transit fatigue during railroad and marine transportati...

Dissimilar metal welds (DMW) joining ferritic steels, i.e., carbon and low alloy steels, to either austenitic stainless steels or nickel-base alloys are frequently required in the petroleum and petrochemical industries. The effect of preheat and post-weld heat treatment on the resistance of DMW to sulfide stress cracking in sour service environment...

Hydrogen-induced cracking (HIC) and stress-oriented hydrogen-induced cracking (SOHIC) tests were conducted on a conventional type A516-70 (UNS K02700) pressure vessel steel exposed to hydrogen sulfide (HâS)-containing diglycolamine (DGA) gas-sweetening environments. Base-line HIC and SOHIC tests were conducted in NACE TM0284-96 Solution A. For the...
