ASTM A1012 Seamless and Welded Austenitic Stainless Steel Condenser and Heat Exchanger Tubes With Integral Fins
seamless and welded ferritic, austenitic and duplex alloy steel tubing on which the external or internal surface, or both, has been modified by a cold forming process to produce an integral enhanced surface for improved heat transfer. The tubes are used in surface condensers, evaporators, heat exchangers and similar heat transfer apparatus in unfinned end diameters up to and including 1 in. (25.4 mm). Boiler tubes are excluded.
Integral Fins Tube Manufacture
The integrally enhanced (finned) tubes shall be manufactured from seamless, welded, or welded/cold worked plain tubes that conform to one of the following ASTM specifications: A213/A213M, A249/A249M, A268/A268M, A269, A688/A688M, A789/A789M, A803/A803M.
Finished tubes shall be clean and free of foreign material, shall have smooth ends free ofburrs, and shall be free of injurious external and internal imperfections. A slight amount of oxidation on the surface resulting from heat treatment after enhancing or bending is acceptable. When the plain tube specification allows for a slight amount of oxidation on the surface resulting from heat treatment, this also is acceptable.

Integral Fins Tube Temper
The tube after enhancing shall normally be supplied in the as-finned temper. When specified by the purchaser, for bending, coiling or other fabricating operations, enhanced portions of the tube may be stress relief annealed or solution annealed.
Heat treatment of enhanced sections, or bend areas, or both, shall be in accordance with the governing plain tube specification.
Integral Fins Tube Ends
Tubes described by this specification shall be furnished with unenhanced (plain) ends.
Integral Fins Tube Packaging and Package Marking
The tube shall be packaged in accordance with the manufacturer’s standard practice, unless otherwise agreed upon between the manufacturer and the purchaser and so stated in the purchase order.
Each shipping unit shall be legibly marked with the name of the supplier, name of the customer, ship to address, purchase order number, alloy designation, size or part number, tube length and number of pieces.
