ASTM A512 Cold-Drawn Buttweld Carbon Mechanical Tubing
ASTM A512 ASME SA512 Standard for Cold-Drawn Buttweld Carbon Steel Mechanical Tubing covers cold-drawn buttweld carbon steel tubes for use as round, square, rectangular or special shape mechanical tubing. The carbon steel can be made unless a specific type of melting process is required by the purchaser.
Heat and product analysis shall be made to determine the specified percentages of chemical composition to which steel tube shall conform to. The tubing shall be free of injurious defects and shall have a workmanlike finish. Unless otherwise specified, both outside and inside surfaces of the tubing shall be coated with a film of rust-retarding oil before shipping.
This specification covers cold-drawn buttweld carbon steel tubes for use as mechanical tubing.
This specification covers round, square, rectangular, and special shape mechanical tubing.
Round tube size ranges covered are outside diameters up to 3 1/2 in. (88.9 mm) and wall thickness from 0.035 to 0.500 in. (0.89 to 12.70 mm).
Optional supplementary requirements are provided and, when desired, shall be so stated in the order.
The values stated in inch-pound-units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
