Introduction:

Stainless steel precision tubes available as thin wall tubes in seamless or welded redrawn condition or as seamless thick wall tubes. High precision tubes are delivered with cold drawn, ground, extremely polished or bright surface, depending on size and wall thickness.

We offer two methods of tube drawing (Sink Drawing and Plug Drawing) and has the ability to create custom shapes using these methods.

Sink Drawing reduces the diameter of a tube by pulling it through a die without the use of a mandrel. In sink drawing, the ID is determined by the OD and wall thickness of the pre-drawn tube. This is the fastest form of drawing, and suitable for drawing of thick walled tubing, as well as drawing of tubes smaller than .062″ OD where using a mandrel is not possible.

Plug Drawing uses an ID mandrel to shape the ID of the tube. This improves ID tolerance, and improves ID finish to as low as 32 RA (finer ID finishes can be achieved with ID Honing (contact sales for details). This process is slower and more expensive due to the need of precision design and manufacturing of the plug, and is limited to IDs larger than .062″.
