Center Enamel: The Global Leader in Bolted Steel Biogas Tanks Manufacturing
In the rapidly evolving landscape of renewable energy and sustainable waste management, biogas stands out as a clean, efficient, and versatile energy source. At the heart of effective biogas production lies the biogas tank—an essential vessel designed to facilitate anaerobic digestion and optimize methane generation. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has emerged as a global pioneer and leader in the manufacturing of bolted steel biogas tanks, setting industry benchmarks through innovative technology, rigorous quality control, and global project experience.
As the world intensifies focus on clean energy, biogas has become a cornerstone in sustainable energy strategies. It is produced through anaerobic digestion, a natural process where microorganisms break down organic materials in oxygen-free environments inside biogas tanks, generating methane-rich gas used for power, heating, or vehicle fuel.
Bolted steel biogas tanks represent a technological leap forward, providing modular, durable, and corrosion-resistant solutions that outperform traditional concrete or welded steel digesters. Center Enamel’s expertise in this domain has redefined standards across continents.
Founded in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd rapidly became a leader by focusing on innovation in the design and fabrication of bolted storage tanks. The company leverages nearly two decades of expertise in glass-fused-to-steel and fusion bonded epoxy tank technologies, extending these advancements to the biogas industry.
Center Enamel holds nearly 200 patents related to enameling and bolted tank innovations and possesses a world-class manufacturing base spanning over 150,000 square meters designed for high-volume, precision production.
Their bolted steel biogas tanks have been successfully deployed in more than 100 countries, contributing significantly to both emerging and developed markets’ green energy infrastructure.
At the core of Center Enamel’s competitive advantage lies its proprietary Glass-Fused-to-Steel coating technology, which fuses molten glass to steel surfaces at temperatures above 820°C, creating an exceptionally hard, chemically inert, and corrosion-resistant layer.
This technology offers:
· Superior resistance to the acidic and corrosive conditions typical in biogas digesters.
· A smooth, non-porous surface minimizing biofilm and sediment buildup.
· Gas and liquid impermeability preventing leakage of methane and tank contents.
· Ease of cleaning and maintenance extending the tank’s lifespan beyond 30 years.
For particular biogas tank configurations or environmental conditions, Center Enamel also deploys fusion bonded epoxy coatings—powder-applied, heat-cured protective layers that add robustness against aggressive biodegradation products.
Center Enamel fabricates tanks from precision-cut, coated steel panels assembled onsite by bolted fastening systems:
· This modularity accelerates transport and installation, especially where infrastructure challenges exist.
· Enables easy expansion or relocation, providing flexible solutions adaptable to evolving energy demands.
· Ensures sealed, airtight connections to maintain digestive efficiency and safety.
The specialized coatings applied on steel panels defend against hydrogen sulfide corrosion and acidic biodegradation—critical challenges in biogas storage. This resistance translates into reduced operational downtime and lower lifecycle replacement costs.
Robust gasketing and bolted connections ensure methane gas containment, critical for safety and environmental compliance. Tanks are engineered to withstand internal biomass pressure, seismic forces, and temperature variances.
Center Enamel designs range from small-scale farm digesters to immense industrial biogas facilities, providing customizable diameter and height options with capacity scalability to meet unique project specifications.
Non-toxic, inert coatings prevent contamination of the biomass and digestate, safeguarding operational integrity. Safety systems incorporate pressure relief valves, gas collectors, and monitoring sensors to meet international safety standards.
Modular design reduces onsite labor and logistical costs. The high-quality coatings reduce maintenance expenses, culminating in excellent total cost of ownership (TCO) over decades.
Farmers integrate bolted steel biogas tanks to convert manure, crop residues, and other agricultural waste into renewable energy and organic fertilizers, promoting circular agriculture.
Cities utilize Center Enamel tanks to transform sewage sludge and organic refuse into biogas for power generation and heat production, reducing urban waste burden.
Food, beverage, paper, and chemical industries incorporate biogas tanks for onsite waste management and energy generation, decreasing processing costs and emission profiles.
Large-scale biogas power facilities rely on Center Enamel’s robust tanks to maximize methane capture, supporting carbon-neutral electricity grids and fuel supply systems.
Center Enamel’s bolted steel biogas tanks have been exported and installed in over 100 countries, including developed markets such as the USA, Canada, Australia, and the EU, as well as emerging regions in Southeast Asia, Africa, and South America.
