A stainless steel precision drawn tube with a polished outside surface – drawn to size, then surface-polished so the OD reads bright and smooth. Polished drawn tube is what instrument builders want when the tube is visible or when fouling must not stick.
Function and Design
A tube carries one job in the assembly, and every tolerance on it exists to protect that job. That is why the tube is inspected between operations, not only at the end.
Design Highlights
- Washdown, humidity and process media are met by stainless, not by a coating.
- Full documentation set available: material certs, dimensional reports, first article files.
- Repeat volumes are priced with in-house tooling and press capacity in mind.
- Material: stainless steel (304 / 316) from verified mills, so repeat orders of the tube land on the same grade every time.
- Process: tube drawing, straightening and finish turning in one flow for the tube.
- Finish: Finish options for the tube: polished to the agreed Ra; alternatives quoted against the drawing.
- Size: Tube size to drawing, with the agreed version governing every later batch.
- Custom: Custom work to print for the tube, with DFM feedback before quotation.
Applications
It earns its place in medical and food-grade devices, industrial gauge tubing, automotive sensor stems.
Our Production Advantage
Most of the difficulty in a tube is invisible: wall consistency, concentricity, burr control. The tube is produced to print, with the features that carry function inspected first.
