As negotiated by the supplier and the purchaser, steel tube with shape and/or size beyond those specified in Figures A.1~A.6 and Tables A.1~A.6 in Appendix A may be supplied. 5.3 Side unevenness Side unevenness of steel tube shall meet those specified in Table 2. 5.4 Radius of outside corner The radius (R) of each outside corner of the section shall meet those specified in Table 3. 5.5 Curvature Curvature of steel tube shall meet those specified in Table 4. When the curvature grade of steel tube is not indicated in the contract by the purchaser, it shall meet the requirements of ordinary grade precision. The high grade dimensional precision, when required by the purchaser, shall be indicated in the contract. 5.6 Twist value The steel tube shall be free from visible twist. The twist values of square steel tube, rectangle steel tube and rectangular trapezoid steel tube shall meet those specified in Table 5. 5.7 Length 5.7.1 General length The general length of steel tube is 2000~9000mm. As required by the purchaser, steel tube with length beyond those specified may be supplied upon negotiation between the supplier and the purchaser and when indicated in the contract. 5.7.2 Specified length and multiple length 5.8 End shape End faces on both ends of steel tube shall be vertical to the axis of steel tube, and the burr on notch shall be removed. 5.9 Weight The steel tube is delivered according to actual weight. When indicated in the contract, it may also be delivered according to the theoretical weight. See Appendix A for the calculation formula of theoretical weight (with steel density of 7.85 kg/dm3).6 Technical Requirements6.1 Designation and chemical composition of steel 6.1.1 For quality carbon structural steels with designations of 10, 20, 35 and 45, the 6.2 Manufacturing method 6.2.1 Steel tube shall be manufactured of seamless steel tube through cold-drawn forming. 6.2.2 As required by the purchaser, steel tube may be manufactured of welded steel tube through cold-drawn forming upon negotiation between the supplier and the purchaser and when indicated in the contract. The weld of cold-drawn welded steel tube shall be kept away from round corner. 6.3 Delivery state The steel tube shall be delivered in cold-drawn state. As required by the purchaser, the steel tube may be delivered in heat treatment state upon negotiation between the supplier and the purchaser and when indicated in the contract. 6.4 Mechanical performance 6.4.3 For structural alloy steel tube with perimeter not less than 240mm and wall thickness not less than 10mm, the impact absorbed energy of standard specimen shall meet the requirements of GB/T 3077. 6.4.4 The sampling position for mechanical performance test of cold-drawn welded steel tube shall be within the base material area. 6.5 Surface quality 6.5.1 The internal and external surfaces of steel tube shall be free from crack, fold, scab, creasing and delamination. These defects shall be completely removed with removed depth not exceed the negative deviation of nominal wall thickness. The actual wall thickness of the removal point shall not be less than the permissible minimum deviation of the wall thickness. 6.5.2 Other local defects not exceed the negative deviation of wall thickness are permissible. 6.5.4 Cold-drawn welded steel tube shall be free from lap welding and over-burning. The outer burr of steel tube weld shall be cleared with residual height not greater than 0.5mm; inner burr of steel tube weld is permissible. As required by the purchaser, the inner burr may be specially specified upon negotiation between the supplier and the purchaser and when indicated in the contract.7 Test Methods7.1 The dimension and shape of steel tube shall be measured piece by piece with measuring instrument of required precision. The measurement method of twist value shall meet the requirements of Appendix B. 7.2 Internal and external surfaces of steel tube shall be visually inspected piece by piece under sufficient lighting condition. 7.3 Sampling method and test method for other inspection items of steel tube shall meet those specified in Table 8.8 Inspection Rules8.1 Inspection and acceptance Inspection and acceptance of steel tube are carried out by the supplier's quality-technical supervision department. 8.2 Batching rules 8.2.1 Inspection and acceptance are carried out for steel tubes according to batches. 8.2.2 Each batch shall be composed of steel tubes of the same designation, furnace 8.4 Re-inspection and judgment rules9 Packaging, Marking and Quality CertificatePackaging and quality certificate of steel tube shall meet the requirements of GB/T 2102. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
