Construction & Engineering
Tank lining refers to the protective coating or layer applied to the interior surfaces of storage tanks to prevent corrosion, contamination, or chemical reactions between the tank material and its contents. It is crucial in industries such as oil & gas, chemical processing, water treatment, and food & beverage storage.
| Material | Description | Applications |
|---|---|---|
| Epoxy Coatings | Resistant to water, chemicals, and abrasion. | Used in water tanks, fuel storage, and chemical tanks. |
| Polyurethane Linings | Flexible and resistant to impact, UV, and chemicals. | Suitable for tanks exposed to temperature variations. |
| Rubber Linings (Neoprene, EPDM, Butyl) | Excellent for abrasion and chemical resistance. | Used in slurry tanks, acid storage, and mining applications. |
| Glass-Flaked Linings | Highly chemical-resistant (acids, alkalis, solvents). | Common in aggressive chemical environments. |
| Polyethylene (PE) & Polypropylene (PP) Linings | Thermoplastic linings for acid and alkali resistance. | Used in wastewater and chemical storage. |
| Ceramic & Brick Linings | Extreme heat and chemical resistance. | Found in high-temperature tanks (e.g., sulfuric acid storage). |
| Zinc & Sacrificial Coatings | Used for corrosion protection in steel tanks. | E.g., ballast water tanks. |
| Factor | Description |
|---|---|
| Chemical Compatibility | Must resist stored substances (acids, solvents, fuels). |
| Temperature Range | Some linings degrade at high or low temperatures. |
| Abrasion Resistance | Needed for tanks with abrasive materials (slurries, solids). |
| Regulatory Compliance | Food-grade (FDA/USDA) or potable water (NSF/ANSI 61) certifications may be required. |
| Installation Method | Spray-applied, sheet-lined, or trowel-applied. |
