Import Biogas Storage Tank With Double Membrane Roof — Buy in wholesale FOB from Supplier in China

This biogas storage tank from Shijiazhuang Center Enamel Co., Ltd. features a double membrane roof system mounted on a glass-fused steel tank body. The double membrane construction consists of an outer weather protection membrane and an inner gas-holding membrane, with a constant operating pressure maintained between them. The supplier indicates that the company has manufactured glass-fused steel tanks since 1989, though buyers should independently verify current production capacity and quality management system status.

Glass-fused steel, also known as glass-lined steel or enamelled steel, combines the structural strength of steel with the corrosion resistance of glass. The fusion process involves coating steel sheets with a glass enamel layer and firing at high temperature, producing a composite material resistant to biogas constituents including hydrogen sulphide and moisture. Typical glass-fused steel tank diameters range from 4.58 metres to 25 metres with standard sheet thicknesses of 3 mm to 12 mm depending on structural requirements. The double membrane roof typically utilises PVC-coated polyester fabric or comparable reinforced polymer membranes with specified methane permeability rates below regulatory thresholds.

The tank serves agricultural biogas plants, municipal wastewater treatment facilities, and industrial organic waste digestion projects requiring reliable gas storage and buffer capacity. The supplier offers customisable capacities, though specific volume ranges are not enumerated in the source data. Shipping terms of FOB and CIF are mentioned, with packaging arranged for safe ocean transit. Buyers should confirm the exact port of loading for FOB shipments, standard lead times for customised diameters, and whether on-site installation supervision or erection services are included in the supply scope.

The available profile information does not include ISO certification details, patent holdings, or specific project references. Buyers should request current business licence, export licence, and quality system certificates directly. The address places the company in Hebei's industrial corridor, a region with established steel and manufacturing supply chains, but this geographic context should not substitute for direct supplier verification.
