FAQ

Answers to frequently asked questions.

How is a tube produced?

K-Tube utilizes premium flat strip stock, which is roll-formed to precise dimensions and then fused using a laser. Subsequent drawing and cold-working "sink" this welded stock to the desired dimensions.

How do I specify I want a smooth bore?

K-Tube offers three ID finishes: welded and drawn, plug/mandrel drawn and plug/mandrel drawn (premium ID surface finish).

Welded and drawn: Our cleanest and most common finish. Utilized in many applications, this is the most economical solution for most people. more...

Plug/mandrel drawn: Stylet insertion or flow applications may benefit from this finish because it provides an improved surface over welded and drawn. more...

Plug/mandrel drawn (premium ID surface finish): Our smoothest, brightest finish is nearly mirror quality and displays a level of excellence unmatched in the industry. more...
