Tubes and Pipes (ASTM)

​Manufacturing program with minimum wall thickness (ASTM)

Vallourec offers steel tubes with specified minimum wall thicknesses according to ASTM standards. The manufacturing program for outside diameters up to 177.8 mm and minimum wall thicknesses up to 27 mm is listed in the table below (please click the image to enlarge):

Intermediate sizes are available on request.
D = Outside diameter
Tmin = Minimum wall thickness

 

The diameter and the wall thickness of the tubes shall be within the tolerance limits given respectively in this tables in case of ordering tubes in outside diameter and minimum wall thickness.
