Various tanks store and transport liquids, gases, or solids. Each type of tank requires a different lining and coating.
Choosing the correct tank lining and coating will save you time and money. It will also prevent the softening, contamination, or failure of your tank’s coating, which can have serious consequences.
Stainless Steel
Tank lining and coatings can protect your tanks from corrosive liquids like acid, chemicals, or water. They also protect the tank’s interior from holidays, discontinuities, and cathodic protection.
Stainless steel is an excellent material for a tank’s exterior, particularly in dry and oxygen-accessible environments. However, it can be challenging to use in environments where the domain has high salinity or humidity.
For this reason, a tank service may need to apply multiple coatings to provide adequate protection for a steel tank.
Thankfully, several tank services offer wet paint coatings that dry to 100% thickness, ensuring they can provide maximum protection. These products are available for various substrates, including aluminum and steel, and are abrasion and corrosion-resistant.
Zinc
When it comes to tank lining and coating, zinc is a superior option. It offers better chemical, abrasion, and heat resistance than stainless steel.
Zinc lining is available in both organic and inorganic forms. The most commonly used inorganic type is a silicate-based paint that cures by reaction with atmospheric moisture.
One of the main advantages of inorganic zinc lining is that it provides excellent corrosion protection and can be repaired without stripping. However, it has some drawbacks.
The major one is that it only provides resistance for pH values between 6 and 9, meaning that any cargo outside this range can damage the coating and force a tank to be reblasted.
Another problem with this type of lining is that it is highly porous and can allow previously carried cargo to migrate into pores and capillaries. This can lead to much tank cleaning work and the risk of contamination in the next shipment.
Polyurethane
Choosing the correct tank lining and coating can save you money on maintenance costs. It can also prevent leaks, contaminants, and corrosion.
Whether you’re looking for a durable, waterproof exterior coating or an abrasion-resistant interior coating, we have the solution. Our products protect tanks in many industries, including oil and gas, chemical, pharmaceutical, and food.
Our three-coat offshore system consists of zinc primer, high-solids epoxy, and polyurethane paint for maximum protection against water, chemicals, and salt water. This system is suitable for locations such as offshore installations, chemical plants, or refineries, as well as on water storage tanks or other metal vessels.
Our polyurea tank lining is highly flexible, abrasion-resistant, and solvent-free. It is USDA-acceptable and NSF-approved to the ANSI 61 standard for potable water storage, which makes it an ideal choice for water and saltwater tanks. It also provides excellent containment, especially for wastewater. In addition, it has a long service life and is easy to clean.
Epoxy
Tank coatings are made of various materials and applied to the outside tanks. They are a great way to protect tanks from corrosion, damage, and other issues.
Several tank lining and coating types are available, but epoxy is one of the best. This coating forms a tough film over the surface of a tank that is resistant to the elements and a wide range of chemicals.
Epoxy is also very durable, so it won’t crack or break if it encounters strong winds, heavy rains, and extreme temperatures. As a result, it is a good choice for water and chemical storage tanks, factories, work areas exposed to the elements, structural components, walls, and floors.
