Custom welded stainless steel tubes

The CSM TRANSFORMING division represents the Group’s vertical integration, where tubes produced by CSM TUBE are further processed into high-precision components.

Special geometries and sections

In addition to standard round tubes, production capabilities extend to complex metal profiles designed to meet specific functional requirements:

• Round/roll-formed, square, and rectangular tubes: manufactured with tight tolerances for pressure, structural, or aesthetic applications.
• Custom-designed special sections: development of unique geometries based on customer technical drawings, ideal for sectors requiring specific mechanical integration.

End forming and machining operations

The functionality of a tube often depends on the precision of its end connections. Cold forming and machining operations are carried out to ensure optimal performance during assembly stages:

• Calibration, socketing, and tapering: operations to achieve precise diameters or gradual section transitions for the insertion of mating components.
• Bead rolling and flaring: mechanical forming processes to ensure leak-tightness, secure sealing elements, or protect tube ends.
• Turning: machining of complex chamfers or precision threading.

High-precision cutting methods

Cutting is the starting point that determines the quality of subsequent processing. Several techniques are available depending on the final application:

• Laser cutting: a versatile technology for clean cuts, slots, and complex perforations along the tube body with minimal tolerances.
• Orbital cutting: ensures a perfectly perpendicular and smooth surface, an essential condition for subsequent automated welding.
• Saw cutting (deburring or brushing): provides clean finishes free of sharp edges, with a noticeable improvement in surface appearance.

Integrated service: from design to just-in-time delivery

The approach of CSM TUBE and CSM TRANSFORMING is based on a technical partnership covering the entire component lifecycle. Through advanced CAD/CAM software, the division supports feasibility studies and rapid prototyping. Quality control, operating across three shifts, monitors every stage of processing using advanced instrumentation to ensure dimensional and functional compliance. This organizational model enables flexible management of pilot batches, technical sampling, and just-in-time batches.

The technical departments of CSM TUBE and CSM TRANSFORMING are available to review your technical drawings and develop tailored solutions for your industrial requirements.
