Epoxy Coated Steel Tanks
Steel tanks have long been integral to industries ranging from water storage to chemical processing. However, combating corrosion has always been a central challenge in maintaining the integrity and longevity of these tanks. Enter epoxy-coated steel tanks, heralded as the epitome of corrosion resistance and durability in the realm of industrial storage solutions.
Epoxy coating involves applying a layer of epoxy resin onto the surface of steel tanks through a meticulous process. This coating not only acts as a barrier against corrosive elements but also enhances the structural integrity of the tank. Epoxy coatings are renowned for their exceptional adhesion properties, ensuring long-term protection against rust and deterioration.
With over 30 years of experience in tank development, production, and construction, Shijiazhuang Zhengzhong Technology Co.,Ltd(Center Enamel) collaborated with the global leading paint and coating manufacturer AkzoNobel to develop fusion-bonded epoxy coating technology. Epoxy coating is an advanced anti-corrosion coating known for its excellent corrosion resistance and adhesion properties. Furthermore, the epoxy coating technology employs a special construction technique - electrostatic spray coating - which enhances the uniformity and adhesion of the coating, thereby effectively extending the service life of the tanks.
Tanks coated with epoxy coating technology not only boast advanced technology and cost-effectiveness but also offer convenient and quick installation. Their quality meets the requirements of standards such as AWWA D103-09 and ISO 9227 / ASTM B117, garnering immediate recognition from customers upon introduction.
Epoxy Coated Steel Tanks are used in various fields including:Potable water, Firefighting water, Wastewater, Slurry, Leachate, Crude oil, Distillate from refineries, Drilling fluid, Brine, Acids, Alkalis, Ethanol, Biofuels, Vegetable oils, Collected rainwater, etc.
Epoxy Coated Steel Tanks Coating
Internal Coating:
Our epoxy coated steel tank is one of the most durable epoxy coatings available on the market.
Each sheet is subjected to high-pressure testing to ensure no defects under test voltage.
Optimal control of external coating overspray ensures internal coating compliance with drinking water regulations.The coating must undergo and pass numerous types of tests to ensure high performance and compliance with international quality standards.The inner surface is coated with factory electrostatic powder coating, providing high-quality and consistent uniformity of gloss.
External Coating:
The external coating consists of a combination of epoxy primer and highly durable polyester topcoat.The external coating must undergo and pass numerous types of tests to ensure high performance and compliance with international quality standards.The formulation complies with appropriate substance controls, enabling the coating to achieve the highest global safety and environmental performance certifications.
