Publication Date: 2022

H2S corrosion, also known as sour corrosion, is one of the most researched types of metal degradation in oil and gas transmission pipelines requiring a wide range of environmental conditions and detailed surface analysis techniques. This is because localized or pitting corrosion is known to be the main type of corrosion failure in sour environments which caused 12% of all oilfield corrosion incidents according to a report from 1996. Therefore, control and reduction of this type of corrosion could prevent such failures in oil and gas industries, and significantly enhance asset integrity while reducing maintenance costs as well as eliminating environmental damage.

Failure Analysis Of 4-Inch Welded Fittings In Treated LPG Service

Product Number: 51322-17850-SG

Author: Sudhakar Mahajanam

Publication Date: 2022

$20.00

Caustic stress corrosion cracking (SCC) is known to occur in carbon steels under tensile stress and exposure to caustic solutions from 115°F to boiling temperatures. Alternating wet and dry conditions tend to increase SCC susceptibility. Localized overheating of the metal, such as solar radiation, heat tracing, steam outs and excursions should also be considered. Caustic SCC was first reported in 1980 when the top of a continuous kraft digester vessel blew off in Pine Hill, Alabama. It was found that the tensile residual stresses present in non-stress relieved carbon steel weld seams and the corrosive environment (caustic) were responsible for the cracking

Pre-commissioning hydrostatic testing of pipelines and the resulting corrosion (MIC) issues are often linked to test water quality, as well as post-test cleaning operations. In a 1998 study, it was reported that localized corrosion (pitting/crevice corrosion) accounted for 20% of failures in the chemical process industry with an estimated one half of those being MIC failures. Identification of MIC failures is not straightforward. Common characteristic features such as pit clustering, “tunneling” of pits, tuberculation, high microbiological counts, presence of sulfides (in the case of sulfate reducing bacteria (SRB)) and preferential weld attack have been used to anecdotally pinpoint field failures towards MIC.

Failure Analysis On A Carbon Steel Pulsation Dampener In Glycol Service Using Statistical Fractography Highlights A Stress Corrosion Cracking Contribution

Product Number: 51322-17774-SG

Author: Bruce Cowe, Hervé Marchebois, Gustavo Gimenes, Laurent Ponson, Nicolas Auvray

Publication Date: 2022

$20.00

A cold-worked carbon steel pulsation dampener located on a glycol circulation pump failed catastrophically in service. The two parts of the failed dampener were projected several tens of meters across the offshore facility. The failure was investigated initially using traditional metallurgical techniques, but this failed to reach a conclusive failure mechanism.

Failure of 24” Common Crude Piping and Formation of Iron Sulfides Due to the Influence of Sulfate & Iron Reducing Bacteria and Methanogens

Product Number: 51322-17545-SG

Publication Date: 2022

$20.00

A leak suddenly occurred at the 24-inch common crude piping from the separators heading to the degassing boot inlets and the wet crude tanks in an oil gathering center. The initial observations showed the leak was due to a deep isolated pit and localized corrosion. Additional inspections by manual ultrasonic thickness (UT) and long range ultrasonic thickness (LRUT) measurements for the 24” common crude line showed similar deep isolated pits (up to 70% thickness reduction) scattered across the length of the 1100 meter piping.

A crossing between buried pipelines and transportation arteries such as railways and highways is a common reality. Nowdays it is ordinary practice, and standards are available for such pratctise¹, to protect such pipelines by encasing them in a wider pipe, named Casing. The goal is to protect the carrier pipe providing an outer shell capable of withstanding mechanical stresses and eventual corrosion, without leakage risk. In usual conditions this kind of safety measure should not be necessary, still due to the difficult maintenance and monitoring accessibility below railways and highways it becomes a dependable protection method and device.

Fiber-Reinforced Polymer (FRP): Resin And Corrosion Barrier Selection - The Testing Behind The Recommendation

Product Number: 51322-17961-SG

Author: Lisa Adkins

Publication Date: 2022

$20.00

Fiber-reinforced polymer (FRP) equipment has been used in a variety of chemical industries for over 60 years. It is critical to choose the correct FRP material for the specific chemical environment. In the chemical processing industry, vinyl ester resins are used in a variety of applications including strong acid and caustic environments, chlor-alkali environments, chlorine, bleach, and fertilizer applications. FRP equipment is used in the oil and gas industry to handle crude oil, fire water storage and underground fuel storage. Regardless of the chemical application, the process for evaluating the resin involves specific testing per ASTM C-581^[1], Standard Practice for Determining Chemical Resistance of Thermosetting Resins Used in Glass-Fiber-Reinforced Structures Intended for Liquid Service.
