Marine flammable gas bottles and gas systems are designed for safe storage and distribution of combustible gases on vessels. These systems include pressurized cylinders, regulators, and piping to ensure controlled gas flow. They must comply with strict maritime safety standards to prevent leaks and fires.

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.
