Scope This Japanese Industrial Standard specifies the carbon steel tubes hereafter referred to as “tubes” used for civil engineering, architecture, steel towers, scaffoldings, struts, piles for suppression of landslide 1 and other structures. Note 1 The tubes used for piles for suppression of landslide are limited to seamless steel tubes and welded steel tubes of under mm in g444 diameter.

This Standard shall not apply to the foundation piles of the welded steel tube of mm or larger in outside diameter and piles for suppression of landslide. Grades and symbols Tubes shall be classified into 5 grades, and their symbols shall be as given in Table 1.

Table 2 Chemical Composition Unit: STK max max max. STK max max max max max. Alloying elements other than those in the above table may be added, if necessary. For gg3444 tube of grade SPS exceeding When the purchaser requires product analysis for the tube made of killed steel, the tolerances for the values given in the above table shall be as specified in Table 1.

In the case of bendability or kis test, the tube shall be free from flaws or cracks on its nis surface. Further, the tensile test for the electric resistance welded and arc welded steel tube exceeding mm in outside diameter may be substituted by the tensile test made on the steel coil or plate, unless expansion forming process is applied.

Seamless, butt-welding electric resistance welding Arc welding electric resistance welding process process process Method manufacture of Outside diameter Full range Full range Over 40 mm 50 mm or under Full range Over mm STK min min. Note 1 The bend test, instead of the flattening test, shall be applied to the tube 50 mm or under in outside diameter only when specified by the purchaser. When the tensile test for the tube under 8 mm in wall thickness is performed using No.

Dimensions, mass and tolerances on dimensions 5. In this case, unless otherwise specified, Class 1 shall be applied. The tolerances on the outside diameter of hot finished seamless steel tubes shall follows Class The tolerances on the outside diameter of electric resistance welded and arc welded steel tubes exceeding his in outside diameter shall follows Class 1 in Table 4, and the tolerances thereof at tube ends shall be within 0.

The outside diameter of tubes exceeding mm in outside diameter maybe determined by the length of circumference. The tolerances on wall thickness of hot finished seamless steel tubes shall follow Class The tolerance on wall thickness of tubes exceeding mm in outside diameter may be agreed upon between the purchaser and the manufacturer.

Appearance The appearance shall be as follows 1 The tube shall be practically straight, and both ends jix be at a right angle to the axis of the tube.

Method jls manufacture The manufacturing method shall b3444 as follows: Chemical composition in JIS G Analysis method The analysis methods shall be in accordance with any one of the following standards: However, the electric resistance welded and arc welded steel tubes exceeding mm in outside diameter shall be in accordance with 2 and 3. Afterward, the test piece taken from this specimen shall be finished g4344 No. For electric resistance welded steel tubes and butt-welded steel tubes, the welded zone shall be jus in the outermost part of bent portion.

In the case of electric resistance welded and but-welded steel tubes, however, the welded zone shall be placed at right angles to the direction of compression as shown in Fig 1. However, the flattening test and the tensile test in welded zone can be omitted when approved by ijs purchaser.

Method of sampling test specimens and number of test pieces. Division of outside diameter Under mm Method of sampling test specimens and number of test piece Take one test specimen from each m or its fraction of tubes of the same dimensions, and then prepare from it one tensile test piece or one bending test piece. Over mm up to and incl. Take one test specimen from each m or its fraction of tubes of the same dimensions, and then prepare from mm it one tensile test piece and one flattening test piece.

In the case of sampling from the tube Take one test specimen from each m or its fraction of tubes of the same dimensions, and then prepare from it one tensile test piece and one for tensile test in welded zone or one flattening test piece. In the case of g34444 for tensile test from the jus strips or plates in coil Over mm The ji of sampling specimens for tensile test from steel strips or plates in coil g34444 be in jos with Group A in JIS G As to the number of tensile test pieces, for steel plates, take one test piece from each lot of plates of the maximum thickness within twice the minimum thickness and at the same time belonging to the same heat, and take two test pieces from each lot exceeding 50 t.

For steel strips, take one test piece from each lot of the same heat and thickness and take two from each lot exceeding 50 t.

The arrangement of items is not specified. However, smaller tubes and those especially specified by the purchaser may be bundled together to be marked for each bundle by suitable means.
