Stainless Outside Diameter (OD) Tube
Sizing is based on the outside diameter and wall thickness (gauge) of the tubing. The standard stainless steel tube is measured by the outside diameter up to 6” size.
Stainless Inside Diameter (ID) Tube
Sizing is based on the inside (or internal) diameter and wall thickness (gauge) of the tubing. The standard stainless steel spiral weld tube is measured by the inside diameter from 6” size onwards.
Our spiral welded tube and fittings are manufactured to internal dimensions.
