2500L 0.9mm Red Mud PVC Biogas Storage Bag for Agricultural Biogas Systems

A 2500L 0.9mm red mud PVC biogas storage bag is a flexible cylindrical gas bag used for agricultural biogas systems, farm biogas collection, waste treatment support, and temporary gas buffering. Compared with rigid gas containers, the flexible body is easier to transport, place, and pack when empty. The diameter, length, inlet, outlet, valve type, pipe connection, and packing method can be customized according to the confirmed gas composition and site conditions.

Gas composition, connection layout, and pressure condition should be reviewed with our team before production starts.

Product Detail

The 2500L / 2.5m3 capacity is suitable for farm biogas collection, agricultural waste treatment support, temporary gas buffering, and project testing where a large fixed gas holder is not required. The 1.8m diameter and 1.0m length provide a clear reference size before custom drawing confirmation.

The 0.9mm red mud PVC coated fabric provides a flexible body for low-pressure gas storage and folding after emptying. Material compatibility should be confirmed according to actual gas composition, outdoor exposure, installation area, expected use cycle, and project safety requirements.

This flexible gas storage bag is designed for storage applications close to external atmospheric pressure. It is not designed to withstand 1 kgf/cm² gauge pressure above atmospheric pressure or additional artificial pressurization. The 20 kPa leak test before shipment is a short-term seal inspection step, not the daily pressure rating.

Inlet size, outlet size, valve type, pipe connector, reinforcement position, and packing method can be adjusted according to the buyer’s gas collection system and installation layout. Confirming these details before production helps reduce connection mismatch during site installation.

Installation and Use Notes

• Confirm gas composition and material compatibility for the agricultural biogas system before production.
• Place the bag on a clean, flat, and smooth support surface.
• Keep the bag away from sharp objects, dragging, cutting, or abrasion.
• Confirm inlet, outlet, valve, pipe connector, and venting layout before production.
• Use the bag only for near-atmospheric storage without additional internal pressurization.
• Do not treat the 20 kPa leak test as a daily operating pressure rating.
• Keep the installation area away from flames, sparks, and unsafe operating zones.
• Confirm farm site gas storage, ventilation, and safety requirements before use.
• Inspect seams, fittings, and pipe connections before filling and after placement.

Production Process

Step	Process
1	Confirm capacity, size, biogas source, pressure condition, and connection drawing
2	Prepare 0.9mm red mud PVC coated fabric and accessories
3	Cut material panels according to the confirmed cylindrical dimensions
4	Weld the bag body and reinforced fitting areas
5	Install inlet, outlet, pipe connector, valve, and reinforcement details
6	Perform short-term leak inspection and check fitting positions
7	Fold, pack, and prepare the bag for shipment

Each step is carried out according to the confirmed specification, covering material cutting, body welding, fitting installation, short-term leak inspection, and packing preparation.

Packing & Shipping

Order Type	Suggested Packing

FAQ

1. Can this 2500L biogas storage bag be customized?

Yes. Capacity, diameter, length, material thickness, inlet, outlet, valve type, pipe connector, reinforcement, logo, and packing can be customized according to the project requirements.

2. What is the capacity and size of this model?

This model is designed as a 2500L / 2.5m3 flexible biogas storage bag with a reference size of 1.8m diameter and 1.0m length.

3. What material is used for this biogas bag?

The specified material is 0.9mm red mud PVC coated fabric. Final material suitability should be confirmed based on gas composition, installation area, and expected use conditions.

4. Can the bag withstand 1 kgf/cm² gauge pressure?

No. This flexible bag is not designed to withstand 1 kgf/cm² gauge pressure above atmospheric pressure. It should be used close to external atmospheric pressure.

5. How should the 1 kgf/cm² pressure note be understood?

It should be treated as an absolute-pressure reference close to one standard atmosphere, not as additional internal gauge pressure that can be applied during daily use.

6. Why do you test the bag at about 20 kPa before shipment?

The 20 kPa test is a short-term leak inspection step used to check seal integrity before shipment. It is not the daily operating pressure rating.

7. What information is needed for a quotation?

Please send the required capacity, dimensions, gas composition, operating pressure condition, inlet/outlet size, valve type, pipe connection, quantity, and destination country.

8. Can the inlet and outlet be changed?

Yes. The inlet, outlet, valve position, pipe connector, and reinforcement area can be adjusted according to the confirmed installation and gas transfer method.

9. Where can this flexible biogas bag be used?

It can be considered for agricultural biogas systems, farm biogas collection, waste treatment support, temporary gas buffering, and compatible near-atmospheric storage applications after project confirmation.

10. How is the product packed for export?

Packing can be arranged by carton, woven bag, pallet, wooden box, or project-specific export packing depending on bag size, fittings, quantity, accessories, and shipping method.
