Chemical storage tank lining is a process of coating the interior of a tank with a layer of material that can withstand exposure to the chemical(s) that will be stored in the tank. The purpose of the lining is to protect the tank from corrosion, chemical attack, and other types of damage that can result from contact with the stored chemicals.
There are various types of tank linings available, and the selection of the appropriate lining material depends on the type of chemical(s) to be stored, the temperature and pressure at which they will be stored, and other factors such as the size and shape of the tank, and the expected service life of the lining.
Some common types of tank linings include:
Epoxy coatings – These are typically used for tanks that will contain aggressive chemicals, solvents, and acids.
Polyurethane coatings – These coatings provide good chemical resistance, and are often used for tanks containing water or chemicals that are less aggressive than those that require an epoxy lining.
It is important to properly prepare the tank surface before applying the lining to ensure good adhesion and durability. This may involve cleaning, sandblasting, and other surface preparation techniques.
Proper maintenance of the tank and the lining is also essential to ensure the long-term effectiveness of the lining. Regular inspections and cleaning, as well as prompt repair of any damage or defects, are important to prevent leaks and other issues that can result in costly downtime and environmental damage.
