Import Biogas Tanks With Membrane Roof — Buy in wholesale FOB from Supplier in China

Center Enamel Co., Ltd. supplies glass-fused-to-steel biogas tanks with double membrane roof systems, engineered for anaerobic digestion and biogas storage. The listed capacity is 50,000 gallons, constructed with corrosion-resistant glass-fused steel panels that bond vitreous enamel to steel substrates. The double membrane roof comprises an outer weather protection membrane and an inner gas-holding membrane, creating a flexible gas storage system that adjusts to pressure and volume changes. This configuration is standard for agricultural digesters and wastewater treatment facilities where gas tightness and structural longevity are critical.

The glass-fused-to-steel construction method involves firing enamel coatings at 820-850 degrees Celsius onto pre-fabricated steel sheets, producing a composite with the structural strength of steel and the chemical inertness of glass. Typical enamel thickness ranges from 0.25mm to 0.45mm per side, with standard grades meeting AWWA D103-19 for bolted steel tanks or EN 15282 for enamelled steel. The membrane roof material is typically reinforced polyester fabric with PVC or TPU coating, with typical gas permeability below 0.5 m³/m²/day at 1000Pa pressure difference. Bolted panel construction allows field assembly without welding, reducing installation time and eliminating hot-work permits on site.

Buyers for this system include agricultural biogas plant operators, municipal wastewater treatment authorities, food waste processing facilities, and industrial effluent treatment plants. The 50,000-gallon capacity suits medium-scale operations producing 200-500 m³ biogas daily. Trade terms require direct confirmation with Center Enamel Co., Ltd., as the listing does not specify binding MOQ, lead times, or pricing. Packaging is described as bulk supply configuration. Payment instruments and Incoterms stated in the source require verification before contract commitment.

Center Enamel Co., Ltd. is located in Guangzhou, Guangdong Province, with the address recorded as Guangzhou 510403, China. The supplier holds an imported tier classification and a harbor trust tier, indicating a profiled but not fully verified status within standard marketplace protocols. The response rate is recorded at 0.00 percent with an average response time of zero hours, which suggests no active response data is available through the platform. Buyers should treat all communication and verification claims as unconfirmed until direct engagement establishes response reliability.

The supplier lists biogas tanks with membrane roof systems as a core product line, with glass-fused-to-steel construction as a stated technical differentiator. No verified factory audit, ISO certification, or specific project references are present in the source data. The company description provided by the supplier emphasises durability, easy installation, and eco-friendly credentials, but lacks specific manufacturing capacity, annual output figures, or in-service track record. Buyers should request factory registration documents, quality management system certificates, and reference installations before committing to volume orders.
