OD, ID & Wall Thickness Explained for Stainless Steel Tubes
We sourced capillary tubing from Arya Tubes for a heating application and kept second-guessing our OD, ID, and wall thickness specs before placing the order. This blog would have saved us that back-and-forth — it explains the OD−2WT=ID formula, how welding and drawing affect tolerances, and how grade ties into dimension. Sharing it with anyone specifying stainless steel tubes for medical, automotive, or industrial builds.
