6.1 General
The various grades and groups of pipe furnished to this International Standard shall be made to a fine-grain practice. Steel made to a fine-grain practice contains one or more grain-refining elements, such as aluminium, niobium (columbium), vanadium or titanium in amounts intended to result in the steel having a fine austenitic grain size.
 
Pipe furnished to this International Standard shall be made by the seamless or electric-weld process as shown in Table C.4 or Table E.4 and as specified on the purchase agreement. Pup joints shall be made from the materials listed in 4.1.34. Material for couplings and coupling stock shall be manufactured by the seamless process. Cold-drawn tubular products without appropriate heat treatment are not acceptable.
 
Casing and tubing accessories shall be seamless and made from the materials listed in 4.1.1.
