About Project
The age of each of the elevated Carbon Steel Tank Silos was approximately 25 years old. They stored and operated a hot mix solution of calcium hydroxide and water. Engineering assessment inspections identified many corrosion problems, structural deterioration, and imperfect and irregular welds on the substrate to be coated.
Coating Job Scope of Work
As part of the surface preparation, high and ultra-high pressure jets of water (Range: 25,000 to 40,000 Psi) were applied to the silo internals for removing deposits of Calcium Hydroxide, which was solidified and strongly adhered to the substrate of the two tanks.
Subsequently, a wet sandblasting surface preparation was done to generate the anchoring profile and required cleanliness for applying the coating. All required structural repairs were performed, including removal of imperfect and irregular welds were removed.
Our Warren Structural Epoxy was sprayed, and the average coating thickness was 1/8” (3 millimeters). Quality Control & Quality Assurance and inspections were performed and they all passed with outstanding values.
The largest contributing resource of renewable energy in Ireland. It is both Ireland’s largest and cheapest renewable electricity resource. In 2018 Wind provided 85% of Ireland’s renewable electricity of our total electricity demand. It is the second greatest source of electricity generation in Ireland after natural gas. Ireland is one of the leading countries in its use of wind energy and 3rd place worldwide.
Conclusion
he Impermeabilization and Rehabilitation Project of the two silos were successfully executed in ten (10) days, in a quality and cost-effective manner, with no safety issues, and within the agreed work schedule with the customer. During the implementation of the project, the plant was able to continue operating at 50% capacity without stopping production. MADERO’s execution of this turnkey Mission Critical Project was a total success. After 10 years of operation, the tank liner was confirmed by the client to be in excellent condition.
