    In 2017 and 2018, Johns Manville built upon the long-term, third-party corrosion testing we started in 2016, and the new results are in. The research sought to explore how corrosion under insulation (CUI) impacts a completely insulated pipe system (pipe, insulation, and jacketing) under conditions designed to accelerate corrosion. The test program started in 2016 with two hydrophobic high-temperature blanket insulations (InsulThin™ HT microporous blanket and a silica aerogel blanket) and in 2017 was expanded to include testing on calcium silicate and expanded perlite insulation.

    It is often necessary to predict the performance of a specific material in a particular environment to determine the inherent corrosivity of the system. Such tests are often substantially different from those used for corrosion inhibitor qualification, particularly in the case of the corrosion testing of corrosion resistant alloys. Predicting corrosivity is especially important when designing subsea equipment, most of which is extremely challenging to repair or replace once it is installed.

    Corrosion under insulation (CUI) is one of the most significant issues facing industrial facility owners, engineers, and maintenance personnel who work with above-ambient process piping and equipment. Unfortunately, CUI can be very difficult to detect, often only being discovered after it has caused significant damage. There are several non-destructive methods for detecting in-situ metal loss without removing the insulation, such as infrared scanning. However, such methods involve costly equipment and can evaluate only a small area at a time.

    We recently published Part 1 & 2 of the blog series,Don’t Settle When It Comes to Vibration. The previous blog addressed several types of insulation that you can use in high-temperature industrial applications where vibration is a significant component of the industrial environment.

    Insulation systems, like all mechanical systems, require periodic inspection and maintenance. While inspection and maintenance are the responsibility of the owner, the fact is that many insulation systems are frequently ignored. With time, insulation systems can be damaged, and if they are not repaired or replaced, they can become ineffective. Insulation contractors can play a key role in facilitating regular inspection and maintenance programs to prevent this outcome.

    Mechanical insulation in commercial buildings is often hidden behind walls, above ceilings, and in mechanical rooms where only a few have access. In manufacturing or industrial facilities, it is more often exposed to the view of all who venture by. Yet, it seems invisible when energy conservation initiatives are investigated, and it is seldom considered from a return on investment perspective.

    For optimum operation, industrial facilities such as power plants require mechanical insulation on pipes, ducts, tanks and equipment. Mechanical insulation in a power plant controls temperature variation to help limit heat gain or loss on surfaces operating at temperatures above or below ambient temperature. An experienced contractor typically manages installation of mechanical insulation in industrial environments.

    The global cost of corrosion is $2.5 trillion annually1. That staggering number is an aggregate of prevention, maintenance, damage, and recovery efforts for the government and private sector alike. In the industrial industry, the battle against corrosion is an ongoing process that can often be both costly and time consuming.

    In spite of improvements driven by the U.S. Pipeline Safety Improvement Act of 2002 and the added emphasis on integrity management, pipeline failures due to internal corrosion continue to occur. The U.S.
