구조용 테이퍼 강관용 ASTM A595 표준
ASTM A595 Standard Specification for Steel Tubes, Low-Carbon or High-Strength Low-Alloy, Tapered for Structural Use covers three grades of seam-용접, round, tapered steel tubes for structural use. Grades A and B are of low-탄소강 or high-strength low-alloy steel composition and Grade C is of weather-resistance steel composition. The tube steel shall be hot-rolled 알루미늄-semikilled or fine-grained killed sheet or plate manufactured by one or more of the following processes: open-hearth, basic-oxygen, or electric-furnace. The tubes shall be made from trapezoidal sheet or plate that is preformed and then seam welded. They shall be brought to final size and 속성 by roll compressing cold on a hardened mandrel. A tensile test shall be done to determine the 항복 강도 and the ultimate 인장 강도 of the tubes.
1.1 This specification covers three grades of seam-welded, round, tapered steel tubes for structural use. Grades A and B are of low-carbon steel or high-strength low-alloy steel composition and Grade C is of weather-resistant steel composition.
1.2 This tubing is produced in welded sizes in a range of diameters from 2 3/8 to 30 in. [60 to 762 mm] inclusive. Wall thicknesses range from 0.1046 to 0.375 in. [2.66 to 9.53 mm]. Tapers are subject to agreement with the manufacturer.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used indepedently of the other. Combining values from the two systems may result in non-conformance with the 표준.
