The Influence Of Insulation Materials On CUI

Posted by John Williams on March 20, 2019

As facilities engineers and operators know, a Corrosion Under Insulation (CUI) mitigation plan is critical to combating the problems that arise from wet insulation and CUI, such as process instability, reduced outputs, loss of containment, and personnel safety incidents. 

But, it's the designer of industrial insulation systems that creates a system that stands the test of time in CUI defense. That being said, the designer has three main weapons in the fight against 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 and, if operating below the atmospheric dew point, vapor barrier. The third and, arguably, least understood element is the choice of insulation material. Historically, hot insulation products have been divided into categories of wetting and non-wetting, or “hydrophobic” materials. The distinction is important because, as pointed out in NACE Standard RP0198-98:

“Because CUI is a product of wet metal exposure duration, the insulation system that holds the least amount of water and dries most quickly should result in the least amount of corrosion damage to equipment.”

A more recent European monograph states flatly:

“Insulation that minimizes water ingress and does not retain water can effectively act as a barrier to CUI.”

Winter Is Coming. Is Your Plant Prepared For A Deep Freeze?

Posted by Barbara Mard on December 13, 2018

As winter weather approaches, power plant operators and managers must remain vigilant in preventing freezing of their equipment. Frozen piping, valves, actuators, and instrumentation systems can result in ruptures, leaks, and failures that have devastating consequences—such as costly downtime and unplanned outages.

Operators and managers must ensure that all means of freeze protection are in place before it is too late. One way to prevent a freeze-related catastrophe is to select and install the right kind of thermal mechanical insulation.

Resiliency, Steam Distribution Networks, and Pyrogel

Posted by Andrea Giles on March 29, 2017

It seems fitting that we exhibited at NACE Corrosion 2017 in New Orleans, a city that's faced so many challenges due to water—one of the key ingredients to the corrosion process.  While corrosion and the prevention of it is a major topic we also recognize the value of resiliency and using Pyrogel aerogel blanket insulation to "keep it dry."

Pyrogel on the High Seas

Posted by Andrea Giles on January 31, 2017

Let's start with two questions:

  1. What's the highest wind speed recorded in the North Sea?
  2. And how is Pyrogel® aerogel insulation related to that figure?

How Does Weather Affect Your Turnaround Schedule?

Posted by Andrea Giles on January 31, 2017

Turnarounds and other maintenance events, both big and small, take lots of planning and preparation. It's an orchestrated event filled with charts, schedules, people, and milestones. So what happens when Mother Nature decides to stir things up with inclement weather?

Staying Warm, Staying Fit with the Help of Aerogel Insulated Apparel

Posted by Andrea Giles on January 31, 2017

Just because it's winter doesn't mean your fitness routine goes into hibernation. 

For many of you, a bike ride or other outdoor activity is still part of your fitness plan. Frost, snow, or cold temperatures aren't going to keep you indoors. However, you also know how important staying warm is—not only to your comfort, but to your fitness goals.
