Shipbuilding Pipe Bending & Sawing

Heavy-Duty Pipe Fabrication for Marine Operations

Shipbuilding and offshore engineering demand massive scale and absolute ruggedness. Piping networks on commercial vessels, container ships, and drilling rigs handle everything from high-pressure steam and fuel lines to seawater ballast systems. These systems rely on thick-walled carbon steel, stainless steel, and copper-nickel (CuNi) pipes that require immense force to cut and bend.

Overcoming Heavy Marine Pipe Challenges

· Large Diameters & Thick Walls: Bending pipes with diameters exceeding 4, 6, or 8 inches requires massive mechanical torque and rigid frame construction.

· Corrosion Resistance Integrity: Materials like copper-nickel are sensitive; improper bending speeds can cause micro-fractures that fail under marine pressure testing.

· Low Volume, High Variety: Shipbuilding often requires custom, one-off large pipes rather than thousands of identical parts. Machine programming must be fast and adaptable.

Wonsten Heavy Industrial Solutions

Heavy-Capacity CNC Pipe Bending Machines

Our large-scale CNC pipe benders feature high-torque hydraulic or heavy-duty electric drive systems built to manipulate thick-walled marine piping up to large diameters.

· Rigid Clamping Systems: Heavy-duty clamping forces prevent pipe slippage during high-torque operations, ensuring exact bend angles.

· On-Machine Programming: The user interface allows engineers to input coordinates directly at the dry dock side, adapting to real-time adjustments on the vessel hull.

Large-Capacity Industrial Band Saws

Our dual-column metal band saw machines slice through solid steel billets and heavy-walled marine pipes cleanly. They deliver perfectly square cuts, minimizing the time your weld teams spend on joint preparation and beveling.
