Center Enamel provide Epoxy Coated Steel Tanks as biogas tanks

In the realm of sustainable energy solutions, biogas has emerged as a pivotal player, offering a renewable and eco-friendly alternative to traditional fossil fuels. Central to the efficient storage and utilization of biogas are high-quality tanks designed to withstand the unique demands of biogas production. This is where Center Enamel excels, offering state-of-the-art Epoxy Coated Steel Tanks tailored specifically for biogas applications.


Understanding Biogas Storage Needs

Biogas, a byproduct of organic waste decomposition in anaerobic conditions, is a valuable source of renewable energy. However, its storage presents challenges due to its composition, which includes methane and carbon dioxide, along with potential corrosive elements. Effective biogas storage solutions must address factors such as gas composition, pressure variations, and long-term durability.

Introduction to Epoxy Coated Steel Tanks


With over 30 years of experience in tank research, production, and construction, Zhengzhong Technology, in collaboration with the globally leading paint and coating manufacturer AkzoNobel, has developed the Fusion-Bonded Epoxy (FBE) coating technology. FBE coating is an advanced anti-corrosion coating known for its excellent corrosion resistance and adhesion. Additionally, the FBE coating technology employs a special application process—electrostatic spraying technology—that enhances coating uniformity and adhesion, effectively extending the lifespan of the tank.


Epoxy Coated Steel Tanks formed using FBE coating technology are not only technologically advanced and cost-effective but also easy and quick to install. The quality meets requirements such as AWWA D103-09 and ISO 9227 / ASTM B117, gaining recognition from customers upon its introduction.
