Steel Tank Rehabilitation
Steel Tank Rehabilitiation
Projects
Project Highlights
- Tank had degraded and was leaking product
- Performed extensive cleaning and patching of internal shell
- Installed carbon fiber (CFRP) on walls and floor to restore strength to the tank
- Applied topcoat matched to protect tank from exposure to its content
The Project In Pictures
The Problem
The scope of work was to rehabilitate an 8,000-gallon insulated carbon steel tank containing magnesium hydroxide. The tank walls and floor showed severe corrosion caused by the corrosive effects of the tank’s contents.
The tank had been subject to approximately 12″ buildup of material on the bottom that had begun to block the discharge pipe connection. When the buildup was cleaned out, it revealed corrosion and several leaks.
The Fix
- A carbon fiber composite system was designed to strengthen and rehabilitate the interior of the steel tank.
- The tank was abrasive blasted and the holes patched using a proprietary repair system.
- The steel loss in the walls and floor was restored to the original design capacity using a multi-layer, bi-directional carbon fiber system.
The Result
The rehabilitated tank interior was lined with a chemical- and temperature-resistant topcoat to protect the repair and the tank from further corrosion and damage for the tank operation content.
The successful repair allowed the owner to avoid a costly tank replacement and extended downtime. Work was completed over a brief PM shutdown.
