Certain Circular Welded Non-Alloy Steel Pipe

The products covered by this order are (1) circular welded non-alloy steel pipes and tubes, of circular cross section over 114.3 millimeters (4.5 inches), but not over 406.4 millimeters (16 inches) in outside diameter, with a wall thickness of 1.65 millimeters (0.065 inches) or more, regardless of surface finish (black, galvanized, or painted), or end-finish (plain end, beveled end, threaded, or threaded and coupled); and (2) circular welded non-alloy steel pipes and tubes, of circular cross-section less than 406.4 millimeters (16 inches), with a wall thickness of less than 1.65 millimeters (0.065 inches), regardless of surface finish (black, galvanized, or painted) or end-finish (plain end, beveled end, threaded, or threaded and coupled). These pipes and tubes are generally known as standard pipes and tubes and are intended for the low pressure conveyance of water, steam, natural gas, air, and other liquids and gases in plumbing and heating systems, air conditioning units, automatic sprinkling systems, and other related uses, and generally meet ASTM A-53 specifications. Standard pipe may also be used for light load-bearing applications, such as for fence-tubing and as structural pipe tubing used for framing and support members for construction, or load-bearing purposes in the construction, shipbuilding, trucking, farm-equipment, and related industries. Unfinished conduit pipe is also included in this order. All carbon steel pipes and tubes within the physical description outlined above are included within the scope of this order, except line pipe, oil country tubular goods, boiler tubing, mechanical tubing, pipe and tube hollows for redraws, finished scaffolding, and finished conduit. Standard pipe that is dual or triple certified/stenciled that enters the U.S. as line pipe of a kind or used for oil and gas pipelines is also not included in this investigation.
