ASTM A513, “Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing,” has just been released as the new 2012 Edition and has been redesignated as ASTM A513/A513M at the same time. Available now from Document Center Inc. in paper or pdf format, the new edition includes both SI units and inch-pound units. It covers round, square, rectangular, and special shape electric-resistance-welded carbon and alloy steel mechanical tubing produced by hot- or cold-rolling.
The types of tubing in the new 20 page ASTM A513 / A513M – 12 are:
- Type 1a, as-welded from hot-rolled steel (with mill scale),
- Type 1b, as-welded from hot-rolled pickled and oiled steel (mill scale removed),
- Type 2, as-welded from cold-rolled steel,
- Type 3, sink-drawn hot-rolled steel,
- Type 4, sink-drawn cold-rolled steel,
- Type 5, drawn over a mandrel, and
- Type 6, special smooth inside diameter.
Heat and product analyses are used to determine the percentages of chemical elements, to which the steel specimens need to conform. Tubing must be free of injurious defects with a workmanlike finish. When specified, tubing can be coated with a film of rust retarding oil before shipping.
