Zerust® ZIF Tape for Corrosion Under Insulation (CUI)

Surface Preparation & Installation Techniques for Pipes

The Problem: Corrosion Under Insulation (CUI)

Insulation is essential for thermal conservation (hot/cold), frost and personnel protection, and controlling sound and condensation throughout the oil, gas, and chemical industries. However, the same insulation can create hidden corrosion issues with the underlying steel substrate. This problem, known as Corrosion Under Insulation (CUI), has been understood for decades but continues to cost the industry millions annually despite existing mitigation methods.

The Solution: Zerust® Inhibitor Fusion (ZIF) Tape

Zerust® Inhibitor Fusion (ZIF) Tape

ZIF Tape is designed to effectively mitigate CUI. It's a corrosion-inhibiting tape made from self-fusing silicone elastomers combined with proprietary Zerust corrosion inhibitors. This unique design allows for easy, ambient temperature application while delivering lasting protection.

Key Benefits of ZIF Tape

• Easy to apply — simply spiral wrap around the prepared pipe under tension.
• Fuses to itself, forming a tight, protective seal.
• Works on both in-service and out-of-service equipment.
• Creates a moisture barrier to protect metal surfaces.
• Inhibitors within the tape provide extra corrosion protection.
• Moisture passing through the tape carries inhibitors to the pipe surface for ongoing protection.

Lab and field studies confirm ZIF Tape's effectiveness in preventing CUI.
