Special Shaped Tube 304 Stainless Steel Pipe Fitting

Special Shaped Stainless Steel Pipe and Tube refers to non-round stainless steel tubing used in various industries. Common applications include product support structures, channels for fiber optics, and liquid dispensing systems. Depending on the structural requirements, shaped tubing can be designed to offer directional strength—similar to I-beams.

All Special Shaped Pipes and tubes are formed using custom dies and straightened using precision tooling. In some cases, a design fee may apply for the engineering required to create the desired profile. Emily Metal produces shaped tubes in alloys like 304 and 316 stainless steel, but other alloys are also available depending on the formability of the shape.

Special Shaped Pipe and Tube Important Considerations

  • Tolerances on non-critical features should be relaxed to reduce production costs.
  • Tight radii or sharp angles increase manufacturing complexity and may be unfeasible.
  • Final cutting and secondary forming can be challenging; Emily Metal uses specialized tooling for accurate, burr-free results.

Manufacturing Process

  • Cold drawn
  • Annealed (with nitrogen protection)
  • Ultrasonic welded
  • Auto shaping and polishing
  • Packed as per requirements

Ends

  • Plain end or beveled end (or as per request)

Surface Finish Options

  • 180#, 220#, 320#, 400#, 600#, HL, MF, 8K, etc.
