What is a Honed Tube?
The honing process uses abrasive polishing stones and abrasive paper to remove small amounts of material from the inner surface of a tube.
Our honed tubes are produced using Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS) processes, ensuring consistent quality and dimensional accuracy.
