Marine welding gas distribution systems deliver shielding and fuel gases to welding equipment on ships. These systems ensure safe, efficient gas flow for various welding processes in marine environments. They include regulators, hoses, and manifolds designed to withstand harsh conditions.

Size: Typically ranges from 1/4" to 2" in diameter for gas distribution lines.

Grade: High-pressure gas systems often use ASTM A106 or ASTM A333 for piping.

Viscosity: Not applicable to gas systems; gases are low-viscosity fluids.

Buoyancy: Gas systems are designed to be neutrally buoyant or secured to prevent floating.

Material: Common materials include stainless steel (316L), carbon steel, or copper-nickel alloys for corrosion resistance.

Pressure Rating: Typically 150 psi to 3000 psi, depending on application.

Temperature Range: -40°F to 150°F (-40°C to 65°C) for standard systems.

Gas Types: Supports argon, CO2, helium, and mixed gases for welding.

Safety Features: Includes pressure relief valves, check valves, and flame arrestors.

Standards: Complies with ASME B31.3, DNV, and ABS marine regulations.
