Product Scope:

ASTM A179 covers minimum-wall thickness, seamless cold-drawn steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. It is a kind of low-carbon tubes shall be made by the seamless process and shall be cold drawn. ANSON could supply usual dimensions vary from 3.20 to 76,20mm for outer diameter, it has very good cold working performance, suitable for flanging, bending with no need of heating edges, hardness of the tubes may not exceed 72 hr or flanging test should be made in order of one of every two of the tubes selected batch of 250 pieces.
