Detection And Location Of Coating Defects And Disbondments On Buried Pipelines With Differential Reflectometry Mapping

Product Number: 51322-18065-SG

Author: Tristan Petit de Servins d’Héricourt, Homero Castaneda

Publication Date: 2022

Corrosion control of buried assets usually involves a double shield: a coating system as a physical insulation barrier, and a cathodic protection system as an additional ad hoc defense. Detection of a corrosion spot at the coating defect stage is the only way to identify the threat before significant metal loss occurs. Furthermore, detection of defects in the coatings of such assets is especially important, since large defects, if left unrepaired, will not only leave the asset locally prone to corrosion, but also drain and weaken the cathodic protection effectiveness for the entire structure. Therefore, identification and characterization of coating anomalies is critical for the integrity of buried assets.

Effect Of Steel Surface Profile Peak Density On Rust Creepage

Product Number: 51322-17584-SG

Author: Russell Draper, Michael Beamish

Publication Date: 2022

$20.00

The spread of disbondment or corrosion from a scribe or holiday in a coating film, for which the terms rust creepage or undercutting are used in this paper is an important mechanism of coating degradation. The mechanism of rust creepage has been well studied by several authors who concur that the mechanism is driven by electrochemical reactions15. The reactions occurring at the discontinuity in the coating (scribe or holiday) involve an anodic reaction in which iron is dissolved. Adjacent to the anodic region, under the coating, a cathodic reaction occurs in which oxygen is reduced to hydroxyl ions.

NACE TM21431-2020, Test Methods to Evaluate Thermal Properties and Performance of Insulative Coatings

Product Number: 21431-2020

Publication Date: 2020

$179.00

HISTORICAL DOCUMENT. The purpose of this NACE International standard test method is to specify test methods and test conditions used to evaluate thermal properties, insulation values, and performance/integrity before and after thermal aging of insulative coatings. Testing for corrosion resistance is not included in this test method.

NACE TM21431-2023, Test Methods to Evaluate Thermal Properties and Performance of Insulative Coatings

Product Number: NACE TM21431-2023

Publication Date: 2023

$109.00

The primary intent of this standard is to specify test conditions that would give a baseline evaluation – one that would allow direct performance comparisons between different insulative coatings. This standard is designed to have practical test procedures with limited test conditions. It also includes Appendix A (nonmandatory) which describes hot plate designs, and Appendix B (nonmandatory) which describes an alternative thermal conductivity test design.

Soluble Salt Contamination: Testing and Cleaning before Coating

Product Number: 51324-20827-SG

Author: Cortney Chalifoux; Alec Kraynak

Publication Date: 2024

$40.00

This paper focuses on the often-overlooked issue of soluble salt contamination testing and removal during surface preparation prior to coating application. Soluble salts, including chlorides, sulfates, and nitrates, left on the surface prior to coating application can lead to osmotic blistering, corrosion, and coating failures. Several standards provide methods to test for soluble salts. However, there is no industry consensus on acceptable contamination levels given the diversity of coating systems and environments. This paper serves as a guide intended to shed light on the specific issue of soluble salt contamination, particularly on carbon steel surfaces. By addressing the nuances and challenges posed by soluble salt contaminants, this paper aims to equip engineers and professionals in the field with the knowledge and tools necessary to navigate the complexities of surface preparation and ensure the integrity and longevity of coating systems on carbon steel surfaces.

The Performance of Phenolic Epoxy Coating after Thermal Exposure for Corrosion Protection in Marine Environments

Product Number: 51323-19046-SG

Author: S. Ahmed, T. Becker, Y. Hou, K. Lepkova, T. Pojtanabuntoeng

Publication Date: 2023

$20.00

Organic coating is the most widely used method of corrosion protection. its corrosion protective abilities depend on physical, chemical and mechanical properties including adhesion to a substrate and essential barrier properties against corrosive species, such as water and oxygen. The durability of corrosion protection coatings is evaluated based on their effectiveness in providing long-term protection to metallic substrates when these materials are exposed to aggressive corrosion environments.
