Author: Shawn Evans

Publication Date: 2019

$20.00

The practice of induced heat to decontaminate a tank (pre-baking) that has been in previous service for re-lining and / or the post application heat curing (force curing) of an applied lining may be considered as a lost art known currently to the few lining specialist within the industry. The objective of the presentation is to inform or remind Owners, Specifiers, Inspectors, Applicators and Vendor Representatives of the requirements and benefits of these processes to obtain a successful relining or tank lining project and additionally attain time savings and prevent cold curing issues.

Forensic Evaluation of Long-Term Galvanic Cathodic Protection of Bridge Pilings in a Marine Environment

Product Number: 51320-14485-SG

Marine environments can be very aggressive and present significant challenges in maintaining key infrastructure from the effects of corrosion. In Florida, thousands of bridges are in coastal areas and are continually, or periodically exposed to saltwater conditions. A clear majority of these bridges were constructed using steel reinforced concrete and are supported by precast pilings situated in saltwater, so for this reason, cathodic protection is a necessary strategy for controlling the effects of saltwater induced corrosion.

Toward the early 1980s, the Florida Department of Transportation (FDOT) began the evaluation of different approaches to control saltwater induced corrosion. Some of these included the use of integral pile jackets, specialty materials for concrete repairs, surface applied coatings and other innovative approaches utilizing galvanic anode technology. One such system was jointly developed with industry partners and sponsored by the Federal Highway Administration (FHWA) using integral pile jackets lined with expanded zinc mesh anodes to apply cathodic protection. This innovative approach provides for the problem of concrete repair while at the same time stopping the on-going process of corrosion both combined in one application. Both laboratory and field trials validated the benefits to this approach and confirmed that the system can mitigate corrosion and extend the useful service life of pilings by more than 20 years.

Corrosion under insulation (CUI) is among the leading damage mechanisms in oil refining and hydrocarbon production facilities. CUI reportedly drives 40-60 % of the piping-related repairs and constitutes 10% of the overall maintenance spending. Numerous conventional and advanced inspection measures look for the occurrence and severity of CUI. On the other hand, the CUI formation reasons, and kinetics may not be well understood with the common inspection strategies. Like any other type(s) of corrosion, the rust scale samples can provide useful evidence in understanding CUI. With clarity on drivers and kinetics, the root cause analysis and decision making for CUI management can benefit from such information on drivers and kinetics. This article addresses the three different case studies on the forensic investigation of CUI via chemical analysis of rust scale samples. Rust samples from various assets in downstream and upstream facilities were analyzed using x-ray diffraction (XRD) which revealed range of corrosion products such as hematite (Fe2O3), goethite (a-FeOOH), akageneite (ß-FeOOH), magnetite (Fe3O4), etc. The study then addresses the kinetics behind these corrosion products and suggests some practical measures for utilizing the forensic information on rust scale(s).

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.

Formicary Corrosion And EAC Of Copper Tubes In Contact With Building Sealant

Product Number: 51322-17846-SG

Author: Kimberly Steine

Publication Date: 2022

$20.00

Blue discoloration of off-white sealant in contact with copper tube at medical facilities under
construction was observed. The copper tube was being installed to transport medical-grade gasses and the sealant was used as an acoustical and smoke sealant at through-wall penetrations. In some areas of one facility, galvanized steel pipes inserts were used as sleeves for the copper pipes through the drywall, while in other areas, the copper pipe penetrated directly through the drywall. Observations of the discoloration prompted an evaluation of the copper tube, sealant, and potential adverse interactions.

Formulated Didecyl Dimethyl Ammonium Bicarbonate/Carbonate (DDABC), a Multi- Metal Corrosion Inhibitor with Relevance to Commercial Surface Preparation and Coatings Technologies

Product Number: 41207-306-SG

Author: Thomas C. Bedard, T. David Burleigh, Joseph Kimler

Publication Date: 2007

$20.00

A new water-soluble quaternary ammonium compound, didecyldimethylammonium bicarbonate/carbonate (DDABC), has been evaluated as a corrosion inhibitor via standard electrochemical tests on steel and shown to be highly effective. At the proper dilution, the inhibitor migrates to the metal/solution interface and forms a monomolecular film on the anodic sites.

Formulating High Performance Coatings with Novel Adhesion Test Methods

Product Number: 41215-939-SG

Author: Yutao Yang

Publication Date: 2015

$20.00

Adhesion performance is required for every coating system. The adhesion between coatings and substrates is one of the most critical determining factors in the overall success of any coating material. Material design and formulation are key components of high-performance coatings and rely heavily on the accurate measurement and evaluation of adhesion in the coating systems.

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

Product Number: 51323-19533-SG

Publication Date: 2023

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.

Hydrocarbon production currently occurs in a variety of onshore and offshore locations. Most offshore production in shallow water (< 500 m) has reached maturity, with most of the more accessible reserves having already been exploited. As a result, exploration and production in offshore environments has been extended to deeper water (> 500 m), which usually incurs more expense and overall project risk for operators and service providers. Production from deepwater oil fields is expected to grow by 40%, to 10 million bpd (10% of total global output), by 2025.
