PowerSleeve® Acid Vessel



This 20″ diameter acid vessel had a bottom end cap which was found to have substantial wall loss. The attached 6″ and 1″ piping also had extensive damage from the corrosive acid contained in the system.

Removing the vessel from service at that point would have been very disruptive and costly, so the plant decided to encapsulate the end cap, as well as the attached piping.


powersleevePowerSleeve® engineered composite reinforcement was chosen for the task. Because of the chemical resistance properties of the 100% solids epoxy matrix, it will contain the product even in the event of hole through of the vessel. The PowerSleeve® has the ability to conform to complex irregular surfaces with an extremely high level of adhesion. Custom, high-grade E-glass and Kevlar® fibers are combined to provide the strength for the pressure containment of the repair.

PowerSleeve® was used in multiple strips to build up layers to encapsulate the end cap of the vessel. It was then installed in successive bands to continue the repair on the 6” and 1” piping. Once cured it creates a uniform and continuous barrier for pressure and product containment.


Complete encapsulation of the vessel and piping was achieved in a short timeframe. The PowerSleeve® installation was a cost effective solution to extend the service life and was completed without process interruption or costly downtime.

The PowerSleeve® engineered composite reinforcement system provided the chemical resistance, conformability and strength properties required for this demanding application.

  • Hydrocarbons? No Problem

    PRT now has a 100% solids epoxy product that adheres in the presence of hydrocarbons such as diesel or gasoline. It actually displaces them from the wetted surface to form a permanent bond.
