Steel packaging requirements of the basic two categories: one is the common type of bundling , the other is similar container with crates loaded 5.1 5.1.1 bundled package to avoid damage to the pipe by baling and transportation process, bundling signs to uniform and consistent . 5.1.2 the same should be the same pipe bundle heat number ( batch ) , with the steel grade , the same specification steel , should not be mixed furnace ( batch ) bundling , inadequate bundle should be labeled small bundle . 5.1.3 each bundle should not exceed the weight of steel 50kg. After the user agrees to increase bale weight, but the most important can not exceed 80kg. 5.1.4 for steel strapping flat end when one end should be aligned , align the ends of the pipe ends differ by less than 20mm, each bundle is less than the difference in length of steel pipe 10mm, but the length difference between the length of pipe in accordance with the usual order of each bundle of steel is less than 5mm, a bundle of steel minister of the longest and not more than 10mm. 5.2 bale form 5.2.1 or greater pipe length 6m, playing at least 8 per bale strapping , divided into three groups , labeled as 3-2-3 ; pipe length is less than 6m, at least a dozen 5 per bundle strapping , divided into three group , labeled 2-1-2 ; ( figure 1 pipe length greater than or equal to 5 meters in length steel strapping strip location diagram) pipe length is greater than equal to 3m, at least three dozen per bundle strapping , divided into three groups , labeled 1-1-1 .
