ASTM A270 TP304 tube in sizes up to and including 12 in. [300 mm] in outside diameter. A270 TP304 sanitary stainless pipe usually refers to the small pipe diameters, normally from 1/2"to 2 1/2", thickness from 0.049 in (1.24mm) to 0.15 in (3.81mm). The maximum O.D. of A270 TP304 tubing is 12 inch (i.e. 304.8 mm).
ASTM A270 Standard Specification for Seamless and Welded Austenitic Stainless Steel Sanitary Tubing. Covers grades of seamless, welded, and heavily cold worked austenitic and ferritic/austenitic duplex stainless steel sanitary tubing. Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process. Heavily cold worked tubes shall be made by applying cold working of not less than 35% reduction of thickness of both wall and weld to a welded tube prior to the final anneal. No filler shall be used in making the weld.
