Marine pipe flanges are specialized connectors used in marine piping systems to join pipes, valves, and equipment securely. Marine piping refers to the network of pipes designed to withstand harsh seawater conditions, corrosion, and high pressure. These components are critical for fluid transport, fuel systems, and ballast operations on ships and offshore structures.

Marine Pipe Flanges:

Size: 1/2" to 24" (DN15 to DN600)

Grade: ANSI B16.5 Class 150 to 2500, PN6 to PN100

Material: Carbon Steel (ASTM A105), Stainless Steel (ASTM A182 F304/F316), Duplex Steel

Pressure Rating: 150 PSI to 2500 PSI

Temperature Range: -20°C to 450°C

Coating: Galvanized, Epoxy, or Rubber Lined

Marine Piping:

Size: 1/2" to 36" (DN15 to DN900)

Grade: ASTM A106, ASTM A312, ASTM A790

Material: Carbon Steel, Stainless Steel (304/316), Duplex Steel, Cu-Ni Alloys

Viscosity: Depends on fluid (e.g., fuel oil 180-380 cSt, seawater 1-1.5 cSt)

Buoyancy: Varies with pipe material and fluid density

Pressure Rating: 10 BAR to 100 BAR

Temperature Range: -50°C to 600°C

Corrosion Resistance: High for seawater applications

Yes, Marine Pipe Flanges and Marine Piping typically comply with maritime standards such as ISO 9001, ASTM, ANSI, ASME, and specific classification society standards like DNV, ABS, LR, or BV, depending on the manufacturer and application.
