Steel Pipes - Pumps, Valves, Piping and Fittings
Carbon steel, stainless steel, and alloy steel pipes are used in marine pump, valve, piping, and fitting systems. Selection depends on pressure, temperature, fluid compatibility, corrosion allowance, welding requirements, and classification-society approval.
ProShipWorks provides end-to-end support to source and supply Steel Pipes 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 ASTM A53, ASTM A106, ASTM A312, API 5L, EN 10216, EN 10217, ASME B16.5, ASME B16.9, ASME B16.11, ISO 15614, and ISO 9606. Exact requirements depend on material, service, pressure, and vessel design. |
|---|---|
| Class Approval | Marine piping materials may require approval or acceptance by DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK, or another vessel classification society. Mill certificates, traceability, nondestructive testing, welding qualification, and pressure-test records may be required. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify material grade, size, schedule, pressure rating, certificates, and coating before installation. Follow approved piping drawings, support spacing, alignment, welding procedures, flange standards, and hydrostatic or pneumatic test requirements. Provide suitable corrosion protection and avoid galvanic contact between dissimilar metals. |
|---|---|
| Maintenance Tips | Inspect regularly for external corrosion, coating damage, leakage, vibration, erosion, and support failure. Check flanges, joints, valves, and drains during planned maintenance. Repair coatings promptly and replace sections that exceed allowable wall-thickness loss. |
| Safety Notes | Depressurize, drain, isolate, and gas-free piping before cutting, welding, or dismantling. Use approved hot-work controls, confined-space procedures, suitable PPE, and calibrated pressure-test equipment. Never exceed the pipe, flange, valve, or fitting pressure and temperature ratings. |
