Marine helium gas bottles are specialized containers designed for storing and transporting helium in marine environments. These systems ensure safe and efficient gas handling, often used for diving, welding, or scientific applications. They are built to withstand harsh sea conditions and comply with maritime safety standards.

Size: Typically available in 50L, 80L, and 100L capacities.

Grade: High-purity helium (99.995% or higher).

Viscosity: Negligible, as helium is a low-viscosity gas.

Buoyancy: Provides approximately 1 kg/m³ of lift in seawater.

Material: Aluminum alloy (e.g., AA6061) or composite materials for lightweight and corrosion resistance.

Pressure Rating: Standard working pressure of 200-300 bar.

Valve Type: Brass or stainless steel with CGA-580 or DIN 477 connections.

Regulator Compatibility: Compatible with high-pressure helium regulators.

Certifications: DOT, ISO, or EN standards compliant.

Operating Temperature: -40°C to +60°C.

Weight: Varies by size (e.g., 50L bottle ~15-20 kg).

Coating: Powder-coated or anodized for durability.

Safety Features: Pressure relief valves and burst discs.
