Size: Typically range from 10L to 50L capacity, with standard diameters of 200mm to 400mm and heights of 500mm to 1500mm.
Grade: Compliant with ISO 20421, EN 1442, and DOT/IMDG regulations for marine flammable gas storage.
Viscosity: N/A (gas storage systems do not measure viscosity; applies to the gas itself, e.g., propane viscosity ~0.01 cP at 25°C).
Buoyancy: Designed to be negatively buoyant to prevent floating; materials and ballast ensure submersion if displaced.
Material: High-strength steel (e.g., P265GH) or composite materials (carbon fiber with epoxy resin) for corrosion resistance.
Pressure Rating: Standard working pressure of 20-30 bar, with burst pressure ≥60 bar for safety.
Valve Type: Marine-grade brass or stainless steel valves with flame arrestors and pressure relief devices.
Temperature Range: Operational range of -40°C to +60°C; compliant with fire resistance standards (e.g., 650°C for 30 minutes).
Weight: Empty steel bottles weigh 15-50 kg; composite bottles are 30-50% lighter.
Certification: Requires DNV-GL, Lloyds Register, or ABS approval for marine use.
