Factors Influencing Early Crack Development in Marine Cargo and ballast Tank Coatings

Product Number: 41206-265-SG

Author: George Mills, Bell Buckle, Johnny Eliasson

Publication Date: 2006

$20.00

Stress development in epoxy coatings applied in water ballast tanks (WBT) on ships can lead to cracking, corrosion, and failure of ship’s hulls, with catastrophic consequences to the environment as well as loss of seamen at sea. Typically, these cracks do not appear during application and curing of the coating but after some finite time of service. The financial wellbeing of the ship’s owner can suffer greatly. To avoid such cracking, it is critical to have a clear understanding of the underlying mechanisms and primary controlling factors behind the coating cracks.

Internal and external coatings have been used extensively for the corrosion protection of a wide range of process components such as flowlines, pipelines, piping, vessels, tanks etc. that are used in oil and gas industry. Coatings are a critical barrier as part of a corrosion management strategy and shall be capable of providing long term corrosion protection in corrosive environment. Coatings are exposed to wide range of temperatures, high pressure environments, and acid gases (H2S and CO2), and are subjected to mechanical damage, etc. during operating service life. The authors’ company has extensive experience of using various coating systems for over 40 years. Fusion bonded epoxy (FBE) coatings and glass reinforced epoxy (GRE) linings are primarily used as internal coatings, and three-layer polypropylene (3LPP), three-layer polyethylene (3LPE), thermal spray aluminum (TSA), and epoxy coatings are used as external coatings in hydrocarbon and water injection service. During design, it is anticipated that coatings will meet expected design life, however, premature coating failures are reoccurring for various reasons, which result in significant oil & gas deferment and unplanned shutdowns. This paper will present two case studies on field experience of different coating systems and contributing factors that led to premature failures. The three main contributing factors to premature failure are quality QA/QC during coating application, incorrect coating selection, and coating damage during installation.

Forgotten Phenomenon: Corrosion of Galvanized Piping Underground

Product Number: 51324-20595-SG

Author: Michael J. Szeliga

Publication Date: 2024

$40.00

Water utilities have begun to install galvanized piping underground as a “new” form of corrosion control. While this is being called a “new” approach, the effectiveness of galvanized piping underground has been widely discussed in the corrosion literature for more than 70 years. This paper will summarize some of the documented findings regarding galvanized piping underground that is presented in the corrosion literature. The paper will also discuss the types of galvanizing available and how that impacts the rate of corrosion on galvanized piping underground.

Formulation Guidelines for the use of Zinc Flakes in Heavy Duty Corrosion Protection Complying with SSPC Paint 29 Requirements

Product Number: 51323-19533-SG

Author: Peter Wissling, Jon Lawniczak

Publication Date: 2023

$20.00

For many years, sacrificial corrosion protective paint formulations based on Zinc consisted of zinc dust at approximate 80% loading and about 10% epoxy binder. This composition is necessary for corrosion protection, as direct zinc to zinc dust contact is only possible at high zinc dust loadings. This goes back to the spherical shape of the zinc dust particles with their low surface area.

Galvanic Corrosion in Water & Wastewater Structures: Coupling Stainless and Carbon Metals Leads to Accelerated Corrosion

Product Number: 41214-840-SG

Author: Vaughn O’Dea, Travis C. Tatum, Pat Barry, Paul B. Higgins

Publication Date: 2014

$20.00

Stainless steel is selected for use in the municipal waterworks industry because of its inherent corrosion resistance properties. Designers oftentimes overlook the associated problems with coupling stainless steel with carbon steel metals. When these materials are electrically connected and placed into aqueous environments (immersion service) accelerated corrosion of the anodic carbon steel metal is initiated.

Galvanic corrosion is one of the eight forms of corrosion classified in corrosion engineering. A galvanic cell is formed when two dissimilar metals are connected electrically while both are immersed in a solution electrolyte. Galvanic coupling of stainless steel and carbon steel metals in water and wastewater structures appears to be a problematic trend that the authors have observed firsthand.

Impact Of Maintenance Activities On Future Integrity Of Transmission Pipelines

Product Number: 51322-17504-SG

Author: Haralampos Tsaprailis, Jiajun Liang, Mike Hill

Publication Date: 2022

$20.00

Transmission pipeline companies utilize successive ILI tool runs to identify, size, and determine the corrosion growth rate (CGR) of pipeline features that may be detrimental to the operation of the pipeline [1, 2]. The importance of back-to-back ILI tool runs in monitoring and maintaining the safe operation of a pipeline is further supported by the methodologies’ incorporation by US regulators for high consequence areas. The calculated CGR from the ILI tool runs is used to determine maintenance digs required to mitigate the identified features prior to the next scheduled re-inspection interval.

Left unprotected, metals corrode quickly which over time contributes to the loss of structural integrity and the failure of buildings, bridges, oil & gas platforms, airplanes, cars and many other metal assets, all of which pose a risk to human safety and the surrounding environment. In 2016, the National Association for Corrosion Engineers (NACE) – now known as AMPP – published a landmark study, well-known to those attending this conference, that estimated the direct cost of corrosion to the world economy as $2.5T per year, equivalent to 3.4% of the Gross World Product (1). In the United States, the annual cost of corrosion is estimated at 3.1% of gross domestic product (2), equivalent to $635B (2018). When including indirect costs, such as asset downtime, ship dry-docking and the impact of bridge collapses, the cost of corrosion is estimated at twice that amount.

Publication Date: 2022

$20.00

As onshore pipeline rights-of-way become more congested and urban sprawl increases, the number of horizontal directional drills (HDDs) will likely increase. HDD is a trenchless pipeline installation method that requires drilling a larger pilot hole where the mainline pipe can be subsequently pulled through the drilled hole. However, HDDs have an increased probability for coating damage, even when coated with traditional mill or field applied abrasion resistant overcoat (ARO). This coating damage includes abrasion, impact, gouging, denting, tearing, bending, etc. and that damage may exist for the life of the pipeline due to an HDD being inaccessible for future maintenance.
