ASTM A498 Seamless and Welded Carbon Steel Heat-Exchanger Tubes with Integral Fins
seamless or welded lowcarbon steel tubes on which the external or internal surface, or both, have been modified by a cold forming process to produce an integral increased surface area for improved heat transfer. The tubes are used in tubular heat exchangers, surface condensers, evaporators, superheaters, and similar heattransfer apparatus in outside diameters up to 2 in. [50 mm], inclusive.
Integral Fins Tube Material and Manufacture
The modified surface tubes shall be manufactured from plain tubes that conform to one of the following ASTM Specifications: A179/A179M, A214/A214M, or A334/A334M.
The modified surface tubes shall be produced by cold forming of steel plain tubes. To comply with this specification, the modified surface and tube material must be integral.
Modified surface tubes shall normally be furnished with unmodified ends, but may be furnished with modified surface ends if specified.
Finished tubes shall be reasonably straight and have smooth ends free from burrs. They shall be free from injurious defects and shall have a workmanlike finish. As light amount of oxidation will not be considered as scale.
Integral Fins Tube Chemical Composition
The steel shall conform to the chemical requirements prescribed in the governing plain-tube specification.
Integral Fins Tube Temper
The tube after modification shall be supplied in either the annealed or as-cold-worked condition, one of which shall
be specified on the purchaser order.
The annealed condition is defined as having both the modified and unmodified portions of the tube conforming to
the heat-treatment requirements of the specified ASTM plain tube.
The as-cold-worked condition is defined as having the modified portions of the tube in the cold-worked condition produced by the modifying operation; and the unmodified portions of the tube confirming to the heat-treatment requirements of the specified ASTM plain tube.
