Circular Welded Carbon Quality Steel Pipe

The merchandise subject to the Orders is certain welded carbon quality steel pipes and tubes, of circular cross-section, and with an outside diameter of 0.372 inches (9.45 mm) or more, but not more than 16 inches (406.4 mm), whether or not stenciled, regardless of wall thickness, surface finish (e.g., black, galvanized, or painted), end finish (e.g., plain end, beveled end, grooved, threaded, or threaded and coupled), or industry specification (e.g., ASTM, proprietary, or other), generally known as standard pipe and structural pipe (they may also be referred to as circular, structural, or mechanical tubing). Specifically, the term "carbon quality" includes products in which (a) iron predominates, by weight, over each of the other contained elements; (b) the carbon content is 2 percent or less, by weight; and (c) none of the elements listed below exceeds the quantity, by weight, as indicated: (i) 1.80 percent of manganese; (ii) 2.25 percent of silicon; (iii) 1.00 percent of copper; (iv) 0.50 percent of aluminum; (v) 1.25 percent of chromium; (vi) 0.30 percent of cobalt; (vii) 0.40 percent of lead; (viii) 1.25 percent of nickel; (ix) 0.30 percent of tungsten; (x) 0.15 percent of molybdenum; (xi) 0.10 percent of niobium; (xii) 0.41 percent of titanium; (xiii) 0.15 percent of vanadium; or (xiv) 0.15 percent of zirconium. Standard pipe is made primarily to American Society for Testing and Materials (ASTM) specifications, but can be made to other specifications. Standard pipe is made primarily to ASTM specifications A-53, A-135, and A-795. Structural pipe is made primarily to ASTM specifications A-252 and A-500. Standard and structural pipe may also be produced to proprietary specifications rather than to industry specifications. This is often the case, for example, with fence tubing. Pipe multiple-stenciled to a standard and/or structural specification and to any other specification, such as the American Petroleum Institute (API) API-5L specification, is also covered by the scope of the Orders when it meets the physical description set forth above and also has one or more of the following characteristics: is 32 feet in length or less; is less than 2.0 inches (50 mm) in outside diameter; has a galvanized and/or painted surface finish; or has a threaded and/or coupled end finish. (The term "painted" does not include coatings to inhibit rust in transit, such as varnish, but includes coatings such as polyester.) The scope of the Orders does not include: (a) pipe suitable for use in boilers, superheaters, heat exchangers, condensers, refining furnaces and feedwater heaters, whether or not cold drawn; (b) mechanical tubing, whether or not cold-drawn; (c) finished electrical conduit; (d) finished scaffolding; (e) tube and pipe hollows for redrawing; (f) oil country tubular goods produced to API specifications; and (g) line pipe produced to only API specifications.
