Versatile PVC Membrane Storage Tanks: Your Solution for Liquids & Gases

Whether you’re managing biogas production, storing industrial liquids, or need a reliable inflatable gas container for helium buffer storage, our customizable PVC membrane tanks deliver exceptional performance. Available in 5m³ to 500m³ capacities, these flexible storage solutions are engineered to meet diverse needs—from small-scale agricultural biogas systems to large industrial liquid storage. Crafted with high-quality PVC/TPU, they combine durability, flexibility, and safety, making them a smart choice for modern storage requirements.

Why Choose Our Flexible Storage Tanks?

• Broad Capacity Range: From compact 5m³ units (ideal for small farms or laboratories) to large 500m³ tanks (suitable for industrial facilities), we cover all scales of storage needs.

• Premium Materials: Constructed from robust PVC/TPU with thickness options (0.4mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm) tailored to your storage volume—ensuring strength for heavy-duty use.

• Multi-Grade Versatility: Available in drinking water-grade, food contact-grade, and industrial liquid-grade options, making them suitable for everything from potable water to chemicals and biogas.

• Safety & Compliance: Manufactured to international export standards, with rigorous in-house lab testing for strength, water tightness, and pressure resistance. Perfect for sensitive applications like inflatable gas containers for helium buffer storage.

• Space-Saving Design: Flexible and foldable, these tanks eliminate the need for rigid infrastructure. They’re easy to transport, install, and store when not in use—saving time and labor costs.

• Complete Accessories: Equipped with essential components: 4-inch BSP inspection hatches, 2-inch BSP male outlet fittings, pressure relief valves, plastic handles with D-rings, and custom ground sheets for added protection.

Real-World Applications & Success Stories

• Biogas Production: A rural community in Europe installed 50m³ PVC membrane digesters to convert agricultural waste into biogas for cooking and heating. The flexible design adapted to uneven terrain, and the food-grade material ensured safe gas storage—reducing reliance on fossil fuels by 40%.

• Industrial Liquid Storage: A chemical plant in Asia used 200m³ tanks to store non-toxic industrial fluids. The corrosion-resistant PVC material withstood daily use, while the pressure relief valves prevented over-pressurization—cutting maintenance costs by 30% compared to steel tanks.

• Helium Buffer Storage: A research facility adopted 10m³ inflatable gas containers for helium buffer storage. The airtight PVC membrane maintained stable pressure, and the lightweight design allowed easy repositioning—supporting seamless laboratory operations.

• Agricultural Irrigation: A farm in Africa deployed 20m³ drinking water-grade tanks to store rainwater for crop irrigation. The UV-resistant material prevented algae growth, and the foldable design made seasonal storage effortless—boosting crop yield by 25% during dry seasons.
