The Hidden Cost of Corrosion Under Insulation

If you operate an industrial facility that transports fluids or gases through piping, corrosion under insulation (CUI) is a real risk. CUI occurs when water penetrates the insulation and sits in contact with metal piping or equipment for an extended period, creating the ideal conditions for rust and oxidation. Collectively, CUI issues are responsible for billions of dollars in maintenance and replacement costs across industries every year, as well as wasted energy consumption and disrupted services and production. 

At Dragon Jacket Insulation, we’ve approached the CUI problem by redesigning industrial insulation from the ground up, rethinking how insulation can accommodate modern industrial applications and avoiding the problems that traditional insulation presents. The result is a product composed of a closed-cell foam core coated with a durable and moisture-impermeable polyurea coating. Our monolithic clamshell design clamps over pipes and fittings with a simple band, obviating the need for separate jacketing and sealing, and eliminating the weak points that create the conditions that lead to CUI.

 

Why Traditional Insulation Systems Fail

Traditional multi-layer insulation systems consist of a porous insulation core (generally, fiberglass, mineral wool, or foam) covered by separate metal (tin or aluminum) jacketing, and sealed with fasteners and tape. In theory, this bulky system creates a moisture barrier that protects your underlying equipment. However, in practice, every joint, seam, and fastener is a potential failure point.

Over time, weather, vibration, impact, and thermal cycling open these seams or cause tears to develop. Water infiltrates. Once insulation becomes saturated with water, the trapped moisture has nowhere to go, and sits against your pipes. The sources of moisture are everywhere:

  • Rain, snow, and humidity in outdoor systems
  • Condensation from chilled or cryogenic lines in interior and exterior systems
  • Leaks from adjacent process systems
  • Washdowns and overspray during maintenance

The end result is moisture intrusion and corrosion of pipes hidden beneath the insulation layers. When wet or damp, the insulation loses R-value, which can accelerate condensation and, consequently, corrosion. However, in most cases, corrosion is undetectable because the jacketing hides the damage until leaks, failures, or costly shutdowns occur.

Ultimately, the problem is not just compromised or inefficient insulation. It is the degradation of the underlying structure, potentially shortening the lifespan of the pipes and fittings by years.

 

A Better Way: Dragon Jacket’s Moisture-Impermeable Design

Dragon Jacket Insulation was engineered to solve the moisture problem permanently. Each section is a single-piece clamshell: a high-R-value (R-6.25 per inch) closed-cell foam core fully encapsulated in a seamless polyurea shell. The clamshell closes tightly over piping, and is secured by metal bands. Unlike fiberglass or mineral wool, Dragon Jacket’s closed-cell core doesn’t absorb or wick water. Because there are no seams, joints, or separate jackets, there’s nowhere for water to enter; the seamless, monolithic design blocks water from every angle. The result is a truly waterproof insulation system that maintains thermal integrity and keeps metal components dry for decades.

 

UV-Resistant, Impact-Resistant, and Built to Last

CUI prevention isn’t solely about keeping water out. The system needs to maintain that protection through every environmental challenge. Dragon Jacket’s polyurea shell is UV-stable, impact-resistant, and chemically inert. That means that, whether exposed to driving rain, coastal salt spray, or freeze/thaw cycles, Dragon Jacket maintains its integrity and performance. Even after years of direct sun exposure or mechanical impact from tools or debris, the outer shell remains intact, continuing to seal out moisture and protect the pipe beneath.

 

Faster Installation, Easier Maintenance

Dragon Jacket arrives prefabricated to exact specifications, either using 3D scanning software or schematics, ensuring a perfect fit. Installation is straightforward:

  • Clamshell the pre-formed section around the pipe.
  • Secure it with stainless steel bands or other approved fasteners.

No adhesives, coatings, or sealants are required. When maintenance is needed, crews can remove a section and reinstall it with a new band when inspection or maintenance is complete; there is no need to replace the insulation. That reusability saves time and cost.

 

Proven Cost Savings Through Long-Term Protection

Repair and replacement costs due to CUI easily dwarf the initial cost of insulation. You can protect your investment by dramatically reducing the risk of water intrusion. Dragon Jacket delivers measurable savings through:

  • Reducing CUI risk: No trapped moisture, no corrosion
  • Stable R-value: Insulation performance remains consistent for decades
  • Reduced maintenance: No patching, recoating, or replacement
  • Extended service life: Typical lifespan exceeds 20 years in outdoor environments

For maintenance managers and engineers, the value is clear: a moisture-impermeable system that is purposely made to prevent failure before it starts.

 

Insulation, not Moisture, is the Real Problem

If corrosion under insulation is a recurring line item or treated as an acceptable risk in your maintenance budget, it’s time to rethink your insulation system. Dragon Jacket’s engineered, moisture-impermeable system provides lasting protection, consistent thermal performance, and the peace of mind that comes with knowing CUI isn’t lurking somewhere beneath the surface of your insulated piping. The technology behind that confidence translates into better bottom line performance for your entire operation in lower initial costs, decreased repairs, and, most importantly, pipes that don’t experience CUI.

The ROI of Switching to Long-Life, Maintenance-Free Insulation

In most cases, industrial insulation isn’t a one-time investment. It’s a system that operates, changes, and ages along with your facility. For many industrial sites using traditional insulation methods, that aging happens far too quickly.

For decades, conventional fiberglass, mineral wool, or other fibrous insulation has been the standard for many industrial applications. It’s a relatively straightforward proposition: hire an insulation subcontractor to cut, wrap, jacket, seal, and secure these insulation materials onto pipes and fittings, and you’re good to go. 

Set-up is easy because it’s an accepted routine. However, the initial cost of installation is only the beginning of your investment. Over the lifespan of a facility, insulation costs multiply. These systems are not designed for longevity: water intrusion, UV degradation, corrosion under insulation (CUI), and other problems arise. Every time underlying equipment has to be inspected and repaired, existing insulation is discarded. Frequent replacement cycles turn a low-cost line item into a recurring drain on capital budgets.

Dragon Jacket Insulation was engineered to stop that cycle. It’s not just insulation; it’s an asset protection system with a measurable return on investment.

 

The Cost of “Good Enough”

Most facilities use legacy insulation because “that’s how it’s always been done.” But as maintenance engineers know, traditional systems rarely reach their expected lifespan.

Within one to two years of installation, moisture begins to infiltrate. Rust blooms unseen beneath the surface. By year five, many systems are already scheduled for replacement. And with each maintenance cycle comes more labor, more downtime, and more waste.

In harsh environments—coastal, outdoor, or process-critical—the cost of these recurring replacements quickly exceeds the original project budget.

 

Engineered for Long-Term Performance

Dragon Jacket Insulation was designed for industrial and municipal environments where failure isn’t an option. Each section is a single-piece, closed-cell clamshell fully encapsulated in a seamless polyurea shell. This monolithic construction is completely waterproof, UV-resistant, and impact-resistant, protecting both thermal performance and infrastructure integrity for decades.

Unlike fiberglass or mineral wool, Dragon Jacket doesn’t absorb moisture, sag, or lose R-value over time. Its closed-cell foam core maintains consistent performance whether installed indoors, outdoors, or across temperature extremes, from arctic freeze to desert heat.

That durability translates directly into measurable ROI.

 

Lower Maintenance, Higher Return

  1. Eliminate corrosion-related failures: Water intrusion and saturation of insulation is the root cause of CUI, a common and costly maintenance problem in industrial piping systems. By keeping moisture out, Dragon Jacket eliminates that risk and the cost of potential repairs that come with it.
  2. Extend service life: Where conventional insulation may fail in one to two years outdoors, Dragon Jacket routinely delivers 20+ years of reliable performance. That means fewer replacements, fewer shutdowns, and a dramatically lower total cost of ownership (TCO).
  3. Reusable design: Every Dragon Jacket pipe section has a clamshell configuration that can be removed and reinstalled without damage. Maintenance crews simply remove the bands, lift the section, complete their work, and re-secure it around the pipe with a new band; no rewrapping, recoating, or re-sealing required. Reusability cuts both labor costs and material waste.
  4. Faster installations: Prefabricated to fit each pipe and component, Dragon Jacket installs up to ten times faster than traditional multi-layer systems. No adhesives, coatings, or subcontractors are required: just shut the clamshell, tighten and secure the band, and move on. Every hour saved during installation translates to project savings and accelerated schedules.

 

The Lifecycle Cost Equation

When evaluating insulation ROI, the true cost isn’t the price per foot; it’s the total lifecycle cost of protection, maintenance, and replacement.

Metric Traditional Insulation Dragon Jacket Insulation
Initial Installation Low material; high labor Moderate material, low labor
Service Life 1-5 years 20+ years
CUI Risk High Negligible
Maintenance Frequent patching or reinstallation Minimal or none
Reusability Single-use 100% reusable
Lifecycle ROI Negative (recurring cost) Positive (one-time cost)

Even conservative projections show that switching to Dragon Jacket can reduce total insulation lifecycle costs by 50–70% over 20 years.

 

Reliability as a Financial Strategy

Every maintenance engineer knows the hidden cost of unreliability: unplanned shutdowns, safety risks, and lost production hours. Investing in long-life, maintenance-free insulation doesn’t just protect pipes; it protects budgets, schedules, and reputations.

Dragon Jacket allows facilities to move from reactive maintenance to proactive asset management. By eliminating insulation failure, you’re extending the lifespan of your infrastructure and ensuring predictable performance year after year.
