TankWrap™: Strength & Protection for Steel Tanks

TankWrap™ is customized for external and internal strengthening of steel tanks. When installed internally, the systems also serve as a structural liner restoring steel loss while protecting against harmful chemicals in immersion. The system can also be used externally for hoop strengthening and protection from external corrosion caused by spillage, environment or other processes in the area.


Why Use TankWrap™️?


Fix small holes with TankPatch™️, a cold-curing localized repair that overcomes the need for hot-work associated with welded repairs that often destroy internal liners.

No Heavy Machinery Needed

TankWrap™ removes the need to move in large amounts of steel with cranes or other machinery.

Value Engineered Repairs

Fix isolated defects, thin-walls, and structural deficiencies using a patch, a full hoop band or wrapping large sections of the tank.

Keep Operations Going

Minimal to zero downtime.

Safer & Easier

Repairs can be completed without hot work.

API 653 Annex J Compliant

API 653 Anex J Compliant for repairing tanks originally constructed to AWWA D100, AWWA D103, API 620, API 650, BS EN 13121-2 and PD 5500. 20-year in-service history, 300 chemicals extensive durability testing, 20,000 hours accelerated testing in acids, caustics, seawater, ultraviolet (UV) radiation and biologically active environments.

Problems We Solve

Isolated TankPatch™

TankPatch™ is a cold-curing localized repair that overcomes the need for hot-work associated with welded repairs. API 653 compliant for shell and roof repairs. TankPatch™ is ideal for smaller scopes of work or widespread isolated defects on tank assets. TankPatch™ is commonly used at the beginning of larger projects as a fast solution to minimize risk on isolated areas of significant wall loss.

Complete Structural Rehabilitation

TankWrap™ is designed to provide hoop strengthening on corroded tanks equivalent to the percentage of steel lost. The system is code-compliant and easy-to-install allowing for repairs to be completed in days or weeks in contrast to traditional repair methods or replacement.

Internal Structural Reinforcement & Chemical Protection

When installed internally, the systems serve as a structural liner to restore steel loss while protecting against harmful chemicals in immersion.
