Drains - Pumps, Valves, Piping and Fittings
Marine drains are fittings and valves used to remove seawater, bilge water, condensate, leakage, and process fluids from pumps, valves, piping systems, and machinery spaces. They may include drain plugs, drain cocks, drain valves, scuppers, strainers, and associated pipe fittings.
ProShipWorks provides end-to-end support to source and supply Drains 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 | Applicable requirements may include IMO SOLAS drainage provisions, ISO 5620 for shipbuilding pipe flanges, ISO 9093 for small craft seacocks and through-hull fittings, and applicable ASTM, EN, or manufacturer standards. Exact compliance depends on the drain type and installation. |
|---|---|
| Class Approval | Where required by the vessel's class rules, drainage components may be supplied with type approval or accepted materials from DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK. Approval is product- and application-specific and must be verified from the manufacturer documentation. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify material compatibility, pressure rating, connection size, flow direction, and class requirements before installation. Fit drains at system low points, provide accessible isolation where required, use suitable marine sealing materials, and support connected piping independently. |
|---|---|
| Maintenance Tips | Inspect periodically for corrosion, leakage, blockage, damaged threads, and seized operating parts. Clean strainers and drain passages, operate valves during planned maintenance, renew gaskets or sealing elements when necessary, and pressure-test after overhaul. |
| Safety Notes | Isolate, depressurize, drain, and cool the system before removal. Treat discharged fluids as potentially hot, pressurized, oily, or contaminated. Use appropriate PPE, prevent uncontrolled bilge discharge, and follow the vessel's permit-to-work and pollution-prevention procedures. |
