Certificated High Pressure Natural Gas Tank Prices 100L CNG ...

High-pressure CNG cylinders (typically 3,000–3,600 psi or 200–250 bar) are specialized storage vessels designed for vehicles and industrial use. They are manufactured in four types (I-IV), with options ranging from heavy-duty steel (Type 1) to lightweight, corrosion-resistant carbon fiber composite (Type 4). These cylinders are durable, often lasting 20 years, and require periodic (3–5 year) inspection.

Key Features & Specifications

Operating Pressure: Generally designed for 3,600 psi (250 bar).
Types:
- Type 1: All-metal (steel or aluminum), affordable, heavier.
- Type 2: Metal liner with fiber hoop wrap.
- Type 3: Metal liner fully wrapped with carbon/glass fiber.
- Type 4: Non-metallic (plastic) liner fully wrapped with carbon fiber; up to 70% lighter than Type 1.
Safety Features: Equipped with Pressure Relief Devices (PRD), typically with fusible material that melts at 219°F to prevent bursting in fires.
Applications: NGV fuel tanks (buses, trucks), CNG cascading storage for refueling stations.

Safety and Maintenance

Testing: Regular hydrostatic tests are required (every 3–5 years) to verify structural integrity.
Installation: Installed in trunks or under vehicles, connected by a high-pressure fuel line.
Inspection: Requires inspection for physical damage, corrosion, and leaks.

Operational Considerations

Filling: Fast-fill stations use temperature compensation to ensure a full 3,600 psi fill despite heating during compression.
Temperature Effects: Pressure changes with temperature; a 70°F ambient fill might show lower pressure (approx. 3,400 psi) once the gas cools.
