Marine Refrigeration Piping in Lagos Apapa Port - Refrigeration Systems

Marine refrigeration piping involves specialized piping systems designed to handle refrigerants in harsh marine environments. These systems ensure efficient cooling for cargo holds, provisions, and other shipboard applications. They are built to withstand corrosion, vibrations, and extreme temperatures while maintaining optimal performance.

Size: Typically ranges from 1/2 inch to 6 inches in diameter, depending on system capacity.

Grade: ASTM A312/A312M for stainless steel, ASTM B88 for copper, or ASTM A53/A106 for carbon steel.

Viscosity: Refrigerant viscosity varies (e.g., R-22: 0.18 cP at 25°C, R-134a: 0.20 cP at 25°C).

Buoyancy: Piping must account for buoyant forces in marine environments; insulation may affect buoyancy.

Material: Stainless steel (304/316), copper, or carbon steel, with corrosion-resistant coatings for marine use.

Pressure Rating: Typically 150-300 psi for low-pressure systems, up to 600 psi for high-pressure applications.

Insulation: Closed-cell foam or elastomeric materials with low thermal conductivity (0.022-0.035 W/m·K).

Temperature Range: -40°C to +120°C, depending on refrigerant and system design.

Corrosion Resistance: Marine-grade materials with anti-corrosive treatments or coatings.

Joint Type: Brazed, welded, or flanged connections for leak-proof performance.
