Flexible Containment Tanks & Gas Bags for professional event, commercial and project applications. Standard size platforms, custom design, material and configuration options from BTCOOPS / Wuxi FENIGAL.
Flexible Containment Tanks & Gas Bags
Collapsible liquid and low-pressure gas storage systems for industrial, emergency, agricultural and field applications. |
Category Overview & Commercial Positioning
Flexible containers are sold by medium compatibility, capacity, fitting layout and fabric system. The website should separate pillow/bladder tanks, open-top tanks and gas-storage bags, with clear notes that material selection is chemical- and pressure-dependent.

Shared Technical Architecture
· Professional products are application-engineered systems. Material, seam/weld method, pressure rating, valve type and reinforcement must be selected from the working medium, temperature, load case and duty cycle.
· Welded flexible structures should use traceable coated fabrics and compatible HF/RF, hot-air or hot-wedge processes; load-bearing or pressure-bearing components require documented production and pressure/leak testing.
· Connections, valves, hoses, regulators, pressure gauges, relief devices, control manifolds and repair kits are treated as part of the system rather than optional decoration accessories.
· Published values in this series are selection platforms. Final safe working pressure, proof test, load/capacity and environmental limits must be stated on the approved technical datasheet for the manufactured unit.
Selection & Quotation Inputs
· Specify medium (air, water, gas, wastewater, fuel-compatible liquid, etc.), required capacity/load and normal/maximum pressure.
· Provide operating and storage temperature, chemical compatibility requirements, UV exposure, abrasion/puncture risk and expected service cycle.
· Define all inlet/outlet sizes, valve standards, hose lengths, fittings, lifting/anchoring points and instrumentation.
· Identify the applicable product/industry standard and required third-party inspection or test certificate before final design.
· For safety-critical lifting, blocking, rescue or pressure isolation products, never substitute a nominal size or pressure rating for a validated working-load / pressure calculation.
