Improving mineral wool CUI performance – next generation

Product Number: 51323-18959-SG

Author: Mikkel Østergaard Hansen, Soeren Nyborg Rasmussen

Publication Date: 2023

$20.00

Mineral wool has been widely used for several decades as the primary thermal insulation on piping and equipment to save energy, protect personnel, and reduce emissions. The products have been favored because they are non-combustible, cost effective, provide excellent (and reliable) thermal performance and are safe, easy, and efficient to install.

Intergranular Stress Corrosion Cracking (IGSCC) of Carbon Steel Equipment

Product Number: 51323-19173-SG

Author: Duane Serate, Simon Yuen, Yashar Behnamian, Jeffrey Venezuela

Publication Date: 2023

$20.00

At the time of a recent maintenance shutdown, cracking was discovered in the repads and parent material in the vicinity of several nozzles along the bottom of two in-situ production treater vessels. Some of the cracks were reported to be through-wall. The vessels were commissioned in 2009 and had been in service for about 13 years before the cracks manifested as through-wall.

Mineral Wool CUI Mitigation Improvements

Product Number: 51324-20798-SG

Author: Ricky Seto

Publication Date: 2024

Mineral wool has been used for well over half a century as insulation to reduce heat loss, provide personnel protection, and protect against hearing loss. Corrosion under insulation (CUI) has been a major topic of interest as process facilities age and experience issues with corrosion, particularly on pipelines. Efforts have focused on reducing any effect of the insulation material on corrosion – e.g., by reducing chlorides, making the insulation hydrophobic, and recently, by upgrading the hydrophobic performance in terms of high-temperature resistance. The next step is to introduce a proprietary corrosion inhibitor within the mineral wool. If water does make its way to the metal substrate, the inhibitor will activate in contact with water to mitigate corrosion. This paper will present the CUI-mitigating efficacy of mineral wool with an integral corrosion inhibitor using the ASTM C1617 test modified for various chloride concentrations above the standard. The paper also discusses corrosion-inhibiting mechanisms, particularly how such mechanisms can modify the environment around steel substrates to mitigate factors that advance stress corrosion cracking.

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
