Marine Manufacturing

Marine and offshore equipment parts are long exposed to salt spray, moisture and alternating loads, with materials mostly chosen from 316L stainless steel, duplex stainless steel and corrosion-resistant alloys. Hanweite machines pump valve bodies, drive shafts and deck machinery parts, focusing on sealing surface quality and thread fit.

Industry Solutions

• Pump valve body: 316L/duplex stainless steel 2205, sealing surface within Ra0.8
• Drive shaft: quenching and tempering + surface hardening, journals precision ground
• Deck machinery parts: thick-wall part machining, welding deformation controlled
• Fasteners and connectors: threads fully inspected with go/no-go gauges

Typical Parts and Processes

Stainless steel-specific cutting tools with low-speed, large-depth-of-cut parameters are used to prevent work-hardened layers from affecting subsequent finishing; welded parts are stress-relieved before finishing.

Quality Assurance

Marine workpieces undergo full dimensional and appearance inspection before shipment, with third-party inspection reports available per customer request.
