KEY CONCEPTS:

• INSULATION SYSTEM DESIGN: CRITICAL ELEMENTS THAT DECREASE CHANCES OF CUI

• WHY HYDROPHOBIC TREATMENTS ARE NOT ALWAYS THE RIGHT SOLU-TION

• CORROSION: KNOWING WHAT CAUSES IT AND HOW TO PREVENT IT

• THE PROPRIETARY CORROSION INHIBITOR THAT ACTUALLY WORKS

“THE BEST OFFENSE IS A GOOD DEFENSE”, A COMMON STRATEGY FOR WINNING TEAMS. WHEN APPLIED TO CORROSION PREVENTION, THE BIG WIN GOES TO THE INSULATION WITH THE BEST DEFENSIVE STRATEGY TO INHIBIT CUI. HERE ARE 4 CRITICAL PLAYS TO ADD TO YOUR SPECIFICATION PLAYBOOK AND PREPARE YOUR INSULATION SYSTEM’S DEFENSE FOR INHIBITING CUI:

INSULATION SYSTEM DE-SIGN:

CRITICAL ELEMENTS THAT DECREASE CHANCES OF CUI

• Personnel protection from hot pipes & vessels

• Improved process control / heat conservation

• Freeze protection• Fire protection• Corrosion protection• Reduced energy consumption costs• Reduction in usage of natural resources• Reduction in CO2 emissions• Fast & compounding ROI

Reasons to Insulate

Sealants can fail; people make mistakes during installation.

There is a backup plan to prevent corrosion if/whenmoisture infiltrates the weather barrier…

It’s supposed to be weather proof, not bullet proof.

HYDROPHOBIC TREATMENTS CAN BE PART OF THE STRATEGY,

BUT ARE NOT A PANACEA

• Expanded perlite, stone wool and thin blanket insulations are treated with hydrophobic additive.

• But what happens at 450≧ °F?

• How does it impact the hydrophobic additive?

THE SCIENCE BEHIND CORRO-SION

Conditions Required for CUI

1. Operating temperatures in the range of 100°F – 350°F

2. Oxygen

3. Liquid H2O must be present

4. Corrosive chemical compounds

5. Acidic pH of water: less than 7

Acidic electrolytes in the water contact the steel pipe surface, which creates an electrical circuit. The completed

circuit polarizes the steel, changing its chemical make up, and turning it into rust.

But how do you inhibitcorrosion under insulation (CUI)?

CORROSION INHIBITING CHEMISTRY PROVEN TO WORK

What is a Corrosion Inhibitor?

XOX™ Corrosion Inhibitor:A chemical compound that decreases the corrosion rate of a metal

A common mechanism for inhibiting corrosion involves formation of a coating (a passivation layer), which prevents the corrosive substance from contacting the metal

Some water has a way of finding its way in. How can a little water absorption possibly be a good

thing?

Once water entersthe system,

springs into action!

A failure in the jacketing sealantcreates a pathfor water ingress

What Activates the Corrosion Inhibitor?

Corrosion Inhibitor

• Not a coating like you might think.

• Activated when water is present.

• Corrosion inhibiting properties are present for the life of the system.

• It works like…

But what is the XOX™ Corrosion Inhibitor and how

does it prevent CUI?
