UNIQUE POLYMER SYSTEMS specialises in providing long-lasting repair and protection solutions for industrial equipment. This case study details the successful repair and protection of a storage tank base at a manufacturing site using UPS 115 XL EXTENDED LIFE METAL and UPS 205 FG FLUID GRADE CERAMIC.

At a manufacturing site, the base plate of a storage tank had become severely corroded, leading to a reduction in its thickness. This degradation posed a risk to the structural integrity of the tank, making it necessary to perform remedial work to prevent the tank from becoming unsafe for continued use.

The primary challenge was to restore the tank base to its original thickness and protect it from future corrosion. The solution needed to be durable and capable of withstanding the harsh conditions within the manufacturing environment, ensuring the tank's long-term safety and functionality.

UNIQUE POLYMER SYSTEMS provided a comprehensive repair and protection solution using UPS 115 XL and UPS 205 FG. The application process involved the following steps:

Surface Preparation

- The tank base was abrasive blast cleaned to ISO 8501/4 SA2.5 (SSPC SP 10 / NACE 2) standards with a minimum angular blast profile of 75 microns. Any remaining uneven surfaces were smoothed out using a mechanical hand grinder, ensuring a clean and level surface for the repair. 

Application of UPS115 XL EXTENDED LIFE METAL

- UPS 115 XL was mixed and applied to the sections of the tank base where the steel thickness had been reduced due to corrosion. The material was applied using a plastic applicator, effectively replacing the lost steel and restoring the tank base to its original dimensions. 

Application of UPS205 FG FLUID GRADE CERAMIC

- After an overnight cure, the repaired areas were machined smooth. The entire tank base was then over-coated with two layers of UPS 205 FG, applied by brush at a nominal thickness of 350 microns per coat. This coating provided a robust barrier against future corrosion, ensuring the long-term protection of the tank base.

‍

The application of UPS 115 XL and UPS 205 FG successfully restored the thickness and integrity of the storage tank base. The protective coating provided by UPS 205 FG ensured that the tank base would be safeguarded against future corrosion, extending its service life and maintaining its structural safety.

This case study demonstrates the effectiveness of UNIQUE POLYMER SYSTEMS' repair and protection solutions in addressing corrosion issues in industrial settings. Our advanced materials and precise application process delivered a reliable solution that ensured the continued safety and functionality of the storage tank.
