Crosses - Pumps, Valves, Piping and Fittings
A marine pipe cross is a four-opening fitting used to divide, combine, or redirect flow in vessel piping systems. Crosses are supplied in butt-weld, socket-weld, threaded, flanged, grooved, and fabricated configurations.
ProShipWorks provides end-to-end support to source and supply Crosses for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common standards include ASME B16.9 for factory-made butt-welding fittings, ASME B16.11 for forged socket-welding and threaded fittings, ASME B16.5 for flanges, ISO 49 for malleable iron fittings, and applicable ASTM material standards. Exact requirements depend on material and service. |
|---|---|
| Class Approval | Approval may be required by DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK for classified vessel piping systems. Requirements depend on the piping service, material, pressure, temperature, and approved manufacturer or fabrication process. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify size, material, schedule, pressure class, branch orientation, and piping-system compatibility before installation. Clean and align pipe ends, use qualified welding or approved joining procedures, and complete pressure or leak testing as required. |
|---|---|
| Maintenance Tips | Inspect for corrosion, leakage, vibration, coating damage, and deformation during piping-system inspections. Check connected supports and joints, and replace fittings showing cracking, severe erosion, or loss of wall thickness. |
| Safety Notes | Depressurize, drain, isolate, and gas-free the piping system before removal or installation. Follow hot-work controls for welding and use compatible materials for the conveyed fluid. Never exceed the fitting's rated pressure or temperature. |
