Acceptance Testing for Coatings in Insulated Service

Product Number: 51217-057-SG

Author: Michael F. MeLampy

Publication Date: 2017

$20.00

Generic descriptions of a coating material does not always ensure that it will perform in the CUI service. Testing and acceptance criteria will help owners to ensure that specific coating materials can provide service as required in industrial CUI environments. The intent of these test procedures is not to rank coatings, but test and accept coatings for use in specifications for actual application.

An Insight to the RBI of Corrosion under Insulation (CUI) and Corrosion under Fireproofing (CUF)

Product Number: 51324-21057-SG

Author: Yashar Behnamian; Duane Serate; Gordon Cheuk Hei Ho; Aaron Mcdonald; Simon Yuen

Publication Date: 2024

$40.00

This paper covers the risk-based inspection (RBI) practices to address external corrosion under insulation (CUI) and corrosion under fireproofing (CUF). The paper discusses risk-based inspection practices of the external corrosion of carbon and low-alloy steels under insulation and fireproofing and the external chloride stress corrosion cracking (ECSCC) of austenitic and duplex stainless steels under insulation, and the external stress corrosion cracking of carbon steel under mineral wool insulation. The RBI methodology described consists of 4 steps, including unit level prioritization, challenging the need for insulation, data validation, and detailed RBI analysis. These steps work together to identify units at higher risk of CUI and CUF, develop an appropriate inspection plan to mitigate CUI and CUF, enhance personnel safety, and reduce unnecessary expenditures. The risk of CUI and CUF failure can be quantified by considering the likelihood of occurrence and severity of consequence.

Can One Coatings be Best for All CUI Service

Product Number: 41216-987-SG

Author: Michael MeLampy

Publication Date: 2016

$20.00

Corrosion under Insulation (CUI) is accelerated corrosion that takes place under insulation typically used to conserve energy, help with process control, and protect workers from temperature extremes. CUI is an issue for facility owners in many industries that use heat or cold in their industrial processes, including chemical processing, refining, fertilizer manufacturing, and power generation. Insulation used in these applications is generally mechanically attached to the substrate vessel or pipeline and is typically covered with cladding. Cladding is typically made out of metal or plastic and is applied to protect the insulation from physical damage and to keep water away from the insulation and substrate.

Comprehensive Corrosion under Insulation (CUI) Management for Cryogenic Service: A Facility-Specific Approach with Broad Industry Implications

Product Number: 51324-21071-SG

Author: Abdullah M. Alratoee; Ricardo S. Costa; Meshary A. Al-Bahli; Faisal M. Al-Mutahhar; Mohamed A. Ahmed

Publication Date: 2024

In the realm of corrosion management, corrosion under insulation (CUI) poses significant challenges, particularly for facilities operating in cryogenic service. A comprehensive approach to understanding and mitigating CUI risks is crucial for ensuring asset integrity, safety, and operational efficiency. This paper presents an in-depth case study of a natural gas liquids (NGL) fractionation facility, demonstrating the successful implementation of a holistic CUI management strategy applicable to a broader industry context. Notably, the facility has faced unique challenges, as some circuits have not been shut down or inspected for the past 40 years. The paper details the extensive work carried out, encompassing risk mapping, mitigation strategies, inspection planning and prioritization, and repair planning. By adopting a systematic approach, the study effectively identifies and addresses CUI risks in the facility's cryogenic service operations. The results of this research contribute to the existing body of knowledge on CUI management in cryogenic service, offering a recommended path forward for the industry to tackle CUI-related issues. By showcasing a comprehensive and adaptable approach, this paper holds great potential to foster increased safety, reliability, and efficiency in the corrosion industry, paving the way for future research and collaboration.

Corrosion Under Insulation (CUI) Management – A Case History

Product Number: 51219-196-SG

Author: David A. Hunter

Publication Date: 2019

$20.00

Pond investigated pressure vessel tank failures which are causing recurring maintenance of $250,000 per year. This challenging project had limitations of space, operational time pressures/vessel availability requirements, cost and replacement variables. This presentation will chronical problems and discuss best practices of specifications, material selection, surface preparation, and application inspection that would have prevented the aforementioned outcome. This paper discusses the fundamentals of composite coatings, industry accepted design standards for their use, and examples of typical uses for these materials that solve problems in varied industries.

Down-the-Hole Withhout a Paddle: Corrosion Mitigation of Wellhead Surface Casings Using IMM Coatings

Product Number: 51220-241-SG

Author: Nicole de Varennes, Norm Spence, Mike O’Donoghue, Vijay Datta

Publication Date: 2020

$20.00

This paper outlines the aggressive service conditions experienced by wellhead casings and the resulting failures seen to date in the Alberta oil patch. Deleterious in-service conditions include; high temperatures and significant temperature fluctuations, expansion and contraction of the steel substrate, and the wet and dry oxidizing micro-environment, the influence of concrete, and a plethora of chlorides and other contaminants elevating the corrosion rate. Previous corrosion mitigation programs and current inspection techniques are reviewed.

In the worldwide oil and gas industry, the application of epoxy phenolic coatings has been a dominant strategy to obtain high heat resistance from coatings and to mitigate corrosion under insulation (CUI) of both insulated carbon and stainless steel pipes operating up to 392°F (200°C). These coatings, however, are sensitive to overapplication, prone to cracking, and costly to repair when damaged.
