The Influence Of Applied Extension Rate And Specimen Geometry On Assessment Of SSC Resistance By Novel NTSSRT Method

Product Number: 51322-17624-SG

Author: Lianlian Liu, Raymundo Case

Publication Date: 2022

$20.00

High strength low alloy (HSLA) steels are preferred for oil and gas pipelines due to their outstanding mechanical properties. Sulfide stress cracking (SSC) has been a major problem for the application of HSLA carbon steel because of the wet H₂S environment which commonly presents in oil and gas industry. Several techniques are applied to the study of SSC of steels, including constant load test with smooth specimens and DCB testing.

Water jetting is frequently used as a surface preparation method mainly during maintenance. However, water-jetted surfaces are prone to the formation of flash rust in the time interval between surface preparation and coating application. The formation of flash rust increases with increasing temperature, relative humidity, and salt contamination concentration on the surface.

THE INFLUENCE OF INSULATION MATERIALS ON CORROSION UNDER INSULATION

Product Number: MPWT19-15362

Author: John Williams, Owen Evans

Publication Date: 2019

$0.00

The designer of industrial equipment and piping has three weapons in the fight against corrosion
under insulation (CUI). The first and primary defense against CUI is a high quality, immersion
grade coating. The second is a properly designed and installed weather barrier jacketing. The third
and, arguably, least understood element is the choice of insulation material. This paper will explore
the ways in which insulation materials influence CUI behavior, presenting results from both
laboratory and field-testing on seven industrial insulation materials and one composite system.
The materials tested were calcium silicate, expanded perlite, cellular glass, mineral wool (both
regular and water-repellent grade), and two types of flexible aerogel blanket material -Pyrogel
XT and Cryogel Z

High strength carbon steel tensile wires confined in the annulus of flexible pipes might experience corrosion when the annulus is flooded with water, either due to outer sheath breaches or to condensation of water molecules permeating from the bore through the inner sheath. Carbon dioxide (CO₂) molecules may also permeate from the bore and reach the annulus, where it dissolves into water to form carbonic acid (H₂CO₃).

The Interaction between Desiccant and Volatile Corrosion Inhibitor

Product Number: 51324-20796-SG

Author: Mitch Fillbach; Mahin Shahlari

Publication Date: 2024

$40.00

Using desiccant is an old, and frequent form of corrosion prevention for metal packaging, relying on reduced humidity to reduce corrosion. Desiccants, while effective in many applications, have been overtaken by Volatile Corrosion Inhibitors (VCI), which overcome some drawbacks of desiccants. VCI are less sensitive to damaged packaging and remain effective even after extended exposure to high humidity. VCI, however, does little to control the humidity inside of the packaging, leading some to want to combine the use of desiccant with VCI. In the following paper we will lay out issues with adsorbing VCI onto the desiccant, and damage to the desiccation ability as well as some of the improvements to longevity and moderation of emission that result when the two technologies are combined. The focus of the paper will be on deliquescent salts, superabsorbent polymers, clay, silica gel, and VCI emitting breathable pouches.

Carbon steel is commonly used as a material for pipelines in oil and gas industry for facilities such as flowlines, down hole tubulars, transmission pipelines. Wide use of carbon steel is conventional due to its economic feasibility, however this kind of steel faces significant internal corrosion problems with corrosion rates reaching up to 10 mm/y if there is exclusion of protective methods. In oil and gas industry such carbon steel pipelines are utilized for transportation of hydrocarbons where they are simultaneously exposed to the co-generated acidic gases (carbon dioxide (CO2) and hydrogen sulphide (H2S)) and water.

The Irony of Creating a Lining Failure in the Process of Inspection

Product Number: 51324-21128-SG

Author: Steve Liebhart

Publication Date: 2024

$40.00

Inspection and shipping schedules often require hydrocarbon storage tanks and rail cars to be removed from service and turned around quickly. This can be for lining/tank inspection or to clean and repurpose it, among other reasons. For whatever reason needed the tank is drained, and any remaining material, including all vapors, must be removed for safe entry into the tank. This process might involve forced heat and ventilation but is not often precisely controlled and even less often are details of the process documented. After cargo is evacuated from the tank the hope is to find the lining intact, and then return it to service as soon as possible. During the process of evacuating volatile material from the tank it is important to handle the lining with care and attention so not to allow the empty tank shell and lining to heat up too fast. This is a dangerous scenario for the well-being of the lining if heated too fast while it contains volatile materials absorbed in the film. When a lining saturated with volatile hydrocarbon is rapidly subjected to increased temperature an equally rapid increase in vapor pressure occurs as the material changes from liquid to gas. Damage to the lining can occur if the vapors can’t escape before generating enough pressure to form blisters and/or cracks. This paper/presentation will discuss the physical phenomenon occurring during the heating and desorption of gasoline from a lining recently removed from immersion service, and how inadvertently damaging the lining during this sensitive process can occur. The purpose of this work is to raise awareness of this phenomenon and show how the long-term performance of a lining can be dramatically impacted in a matter of minutes if not appropriately cared for. Some guidance on how to avoid this problem will also be discussed.
