Pipe Bending Machines for the Special Requirements of Shipbuilding

Rohrleitungssystem auf einem Tankschiff mit komplexen Rohrverläufen für maritime Anwendungen

Piping systems are among the most important infrastructures on board ships and offshore installations. At the same time, limited installation space, large tube dimensions, and demanding materials place high requirements on production. Pipe bending machines for shipbuilding must therefore ensure both high precision and process stability when handling varying tube geometries.

Schwarze-Robitec develops pipe bending machines for processing thick- and thin-walled tubes, flanged tubes, and double-walled piping systems. The machines support shipyards, maritime suppliers, and offshore companies in manufacturing piping systems in a space-saving, precise, and cost-efficient manner.

Further details on the individual product series can be found on the /en/products/.

Pipe Bending Machines for Maritime Piping Systems

In shipbuilding and offshore applications, piping systems are used for a wide range of purposes – from utility lines on cruise ships and process piping on tankers to piping systems for offshore platforms and offshore wind farms.

Different tube dimensions, limited installation space, and high quality requirements demand robust and repeatable manufacturing processes. Schwarze-Robitec offers heavy-duty pipe bending machines for the cost-efficient production of complex tube geometries in new shipbuilding projects, retrofit projects, and offshore manufacturing.

Your benefits at a glance

Safely process large-diameter pipes for shipbuilding

The heavy-duty series from Schwarze-Robitec is designed for pipe sizes up to NPS 18.
Typical applications in shipbuilding often range from NPS 2 to NPS 12.

 

Complex 3D geometries in a single operation

CNC-controlled bending processes make it possible to produce many components without additional welded joints. This reduces manufacturing steps and supports consistent component quality – a key advantage for safety-critical piping systems in shipbuilding.

 

High machine rigidity for demanding materials

Large pipe dimensions and high-strength materials generate significant process forces. The robust design of the heavy-duty machines ensures stable conditions throughout the bending process.

 

Productivity through reduced setup times

In particular, the CNC HD MW series offers significant advantages when handling different pipe types and variant production. The multi-level tooling setup improves machine availability and reduces unproductive downtime.

Frequently Asked Questions About Pipe Bending Machines in Shipbuilding

Which pipe diameters can pipe bending machines for shipbuilding process?

Heavy-duty pipe bending machines from Schwarze-Robitec can process pipe sizes up to NPS 18. The specific machine configuration depends on the material, wall thickness, and bending requirements.

For which types of ships are the pipe bending machines suitable?

The machines are used for applications involving cruise ships, cargo ships, tankers, and naval vessels, as well as offshore installations and offshore wind farms.

Which types of vessels are these pipe bending machines suitable for?

Typical materials include carbon steel, stainless steel, copper, super duplex, and Inconel. For each material, the bending tools and process parameters are specifically designed and optimized accordingly.

Which bending radii are possible?

Typical bending applications in shipbuilding typically range from 2D to 5D. Depending on the pipe dimensions, material, and tooling concept, even tighter bending radii can be achieved.

Why are pipes bent instead of welded in shipbuilding?

Bent pipe components reduce the number of required welded joints. As a result, manufacturing effort, inspection requirements, and potential sources of error can be reduced.

What advantages do CNC pipe bending machines offer in shipbuilding?

CNC pipe bending machines enable reproducible results, reduce manual intervention, and support the production of complex 3D geometries in a continuous manufacturing process.

Can the machines be integrated into existing production systems?

Yes. The control system can be connected to MES and ERP systems via standardized interfaces such as OPC UA.

Which machine is suitable for new-build shipbuilding projects?

For higher production volumes and recurring components, the CNC HD and CNC HD MW series are particularly well suited. They support automated processes and enable short setup times.

Which machine is suitable for repair and retrofit projects?

For single parts, small production runs, and frequently changing requirements, the semi-automatic SR series is often the most economical solution.
