The packaging requirements of steel pipes are basically divided into two categories: one is ordinary bundling, and the other is loading with containers similar to turnover boxes
1. Bundling and packaging
1.1 Steel pipes should be protected from damage during bundling and transportation, and the bundling labels should be unified and consistent.
1.2 The same bundle of steel pipes should be steel pipes of the same furnace number (batch number), the same steel grade, and the same specification. Mixed furnaces (batches) should not be bundled, and less than one bundle should be bundled into small bundles.
1.3 The weight of each bundle of steel pipes should not exceed 50kg. The bundle weight can be increased with the user's consent, but the maximum weight cannot exceed 80kg.
1.4 When bundling flat-end steel pipes, one end should be aligned, and the difference between the aligned ends is less than 20mm. The length difference of each bundle of steel pipes is less than 10mm, but the length difference of each bundle of steel pipes ordered according to the usual length is less than 5mm, and the longest and second longest in a bundle of steel pipes does not exceed 10mm.
2. Bundling form
2.1 If the length of the steel pipe is greater than or equal to 6m, each bundle shall be tied with at least 8 straps, divided into 3 groups, tied in 3-2-3; if the length of the steel pipe is less than 6m, each bundle shall be tied with at least 5 straps, divided into 3 groups, tied in 2-1-2; if the length of the steel pipe is greater than or equal to 3m, each bundle shall be tied with at least 3 straps, divided into 3 groups, tied in 1-1-1.
If there are special requirements, 4 plastic clasps or nylon rope loops can be added to a single steel pipe. The clasps or rope loops should be tied firmly and should not be loose or fall off during transportation.
Galvanized steel pipe logistics transportation-packaging precautions
1. When choosing the packaging material, pay attention to the firmness and tensile strength of the material, and it should have thickness to protect the hot-dip galvanized pipe.
2. When packing, pay attention to the tension of the packaging tape and the rope, and do not be too tight or too loose to avoid affecting the shape of the hot-dip galvanized pipe.
3. When packing, pay attention to the gap between the pipe and the packaging material to avoid movement and collision of the pipe.
4. Pay attention to the influence of the external environment when packaging, and pay special attention to the firmness and moisture-proof measures of the packaging in humid, high-temperature, high-pressure and other environments.
5. The packaged hot-dip galvanized pipes should be placed in a dry, ventilated, and cool place, and should be avoided from direct sunlight to avoid affecting the quality of the pipes.
