ASTM B241/B241M, “Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube,” has just been updated. The new 2016 Edition is available from Document Center Inc. in both paper and pdf formats — it can be included in your enterprise solution, Standards Online, as well. This is an extensive revision. There is almost no section of the specification that remains untouched!
ASTM B241/B241M is used extensively throughout industry. It covers aluminum and aluminum–alloy seamless pipe in a variety of alloys. There are extensive tables with the details required. Sizes of pipe are taken from the ANSI H35.2 and ANSI H35.2(M). A new feature of the specification is the addition of seamless extruded pipe and tube for oil and gas transmission (formerly part of ASTM B354/B354M).
Why are the changes so extensive in this new 2016 Edition? One of the alloys referenced in this standard has been deactivated by the Aluminum Association. So it has been removed from all tables in the ASTM B241/B241M. This means you’ll see new items in the referenced standards section, have new references in many of the various clauses, and a number of references removed as well. Further, AMS 2772 has become the default heat treatment specification.
Another area of the standard with an extensive revision is the terminology section. Changes also appear in Clause 4, ordering information, Clause 5, materials and manufacture, Clause 7, composition, Clauses 8, 10 and 11, all on heat treatment as noted above, Clause 9, tensile properties, Clause 13 on cladding, Clause 14 on dimensional tolerances, Clause 15 on general quality, Clause 16 on internal quality, and Clause 19 on identification marking of product. Even Annexes A1 and A3 have been updated. Whew! Have I convinced you that you must have this new edition yet?
