Tank linings are used to protect the interior from damage due to the contents of the tank. The possibility of corrosion is one of the reasons why the choice of tank linings is a very important consideration to make.

Liquids of any form, be it ordinary potable water or specialized chemicals, have different requirements because of their unique effects on containment tanks. Tank linings play a critical role in preventing the growth of health-threatening micro-organisms that breed when the tank sustains liquid permeations from minute cracks and tears. Tank linings are also essential for the prevention of spillage that can lead to serious safety and health risks.

Anti-Corrosive Tank Linings

Because tanks are often constructed of steel, aluminum or concrete, many tank linings are manufactured to cater to tanks made of these materials.

The most common criteria in choosing the best anti-corrosive lining product for any particular tank are the “best-fit” criteria. This means choosing linings that are specifically designed for the tank’s properties and characteristics, and what they are meant to contain. If the presence of any chemical is most common in a tank, then the lining products to use must ensure protection and no adverse reaction to this chemical.

Tank lining materials that comply with industry standards are then applied to specification. The method of application may vary depending on the expertise and the way of working of painting contractors. The specific requirements of the tank come into consideration, such as in cases where large areas often require the use of airless sprays, and hard-to-reach corners and seams require careful manual application.

As part of an effective quality control system, monitoring, testing, results interpretation and implementing the appropriate actions for any problems that may arise all throughout the project is also an integral part of the whole tank lining process.

Prevent Corrosion with the Help of Expert Painting Contractors

After all relevant factors have been considered, from understanding the effects of corrosion, to choosing the anti-corrosive tank lining product, to the importance of correct application, one other crucial factor to consider is the choice of certified manpower.

A review of the contractor’s portfolio will yield valuable information such as the quality of coatings that the contractor often use, the coating processes they practice, their quality control procedures, and any third-party accreditation they have earned.

When high-quality tank linings have been successfully applied, corrosion is halted from spreading, lessening the necessity of frequent maintenance and repair. When repairs are few, the useful life of the tank is lengthened, which has a direct effect on cost.
