Tubular fabrication and processing

Pipe and tube processing turns mill stock into structural frames, guards, handrails and formed components. Cutting can add holes and copes, while bending creates changes of direction within a continuous profile, subject to the design and selected route.

During engineering review, bend radii, straight lengths, end conditions and weld requirements are considered together. For fluid lines, pressure, cleanliness and test requirements need to be defined separately in the project specification.

  • 3D tube laser cutting, sawing, coping and slotting as applicable
  • CNC rotary draw bending with mandrel support where needed
  • Fixtured welding and specified protective finishing

Tube processing capabilities

Operations are selected and sequenced around the drawing, material and production volume.

  1. 01

    Precision cutting and notching

    Saw or tube laser cutting can produce cut lengths, copes, holes and interlocking slots according to the selected process.

  2. 02

    CNC mandrel bending

    Rotary draw bending can use internal mandrel support to manage cross-sectional distortion and wall thinning where the geometry requires it.

  3. 03

    End forming and profiling

    Flaring, expanding, reducing, beading or flattening can prepare ends for the specified joint or mechanical fit.

  4. 04

    Fixtured welding and assembly

    MIG or TIG welding, where specified, uses an agreed fixture and inspection plan to manage frame geometry and joint requirements.

  5. 05

    Finishing and inspection

    Deburring and specified coating or plating are planned with dimensional checks, check fixtures and records as required by the order.

Design for manufacturability guidelines

Early geometry decisions can simplify tube bending, fixture setup and finishing.

  • Review the centerline radius

    A radius around 1.5 to 3 times the outside diameter is a common starting range for round tube, not a universal limit. Confirm it against grade, wall, tooling and appearance requirements.

  • Standardize bend radii

    Using the same radius where practical can reduce tooling changes and setup complexity.

  • Leave straight clamping length

    Allow enough straight tube between bends and near ends for the bender to grip the part securely.

  • Plan interlocking joints

    Laser-cut tabs and notches can help locate members in the welding fixture when suitable for the design.

  • Specify weld and finish details

    Show weld locations, acceptance criteria, surface preparation and finish requirements on approved drawings.

Pipe and tube questions

What is centerline radius?

It is the radius measured to the centerline of the tube bend. A suitable value depends on the material, outside diameter, wall thickness, tooling and the desired appearance.

What is the difference between pipe and tube?

Pipe is commonly specified by nominal size and schedule, while tube is commonly specified by outside dimensions and wall thickness. Use the applicable product standard on the drawing.

Can bend data be developed from a sample?

A sample can be reviewed as an input to drawing and bend-data development. Measurement, approval and any prototype work are defined before production.

Can material certificates be supplied?

Material grade and traceability requirements should be stated at quotation. Mill certificates or other records can be included when available and agreed in the order.

Can tube parts include sheet metal brackets?

Frames with brackets, gussets or base plates can be reviewed as a combined fabrication and assembly scope.

Have a tube part to source?

Share your drawing, material, expected quantity and finish requirements so we can review the process route and quote scope.
