What should be paid attention to in the process of storage and transportation of stainless steel pipes

When the stainless steel pipe is packed and transported, it is necessary to act according to scientific and reasonable rules to maximize the integrity of the stainless steel pipe in the course of travel. The following are the rules of operation.
When storing stainless steel pipes, stainless steel pipes can’t be directly stacked on the ground, steel plate or cement floor. The distance between the first tier and the ground is not less than 0.20m. In order to prevent the damp, dust and pollution of the stainless steel pipe, the stainless steel pipe is forbidden to be placed in the dust and wet place. The ends of the stainless steel pipe must be protected by the plastic paper or the packing bag to avoid the dust entry.
Next, the rack or stack should be arranged neatly and clearly marked. Stainless steel pipes should be placed on the designated rack or stack according to the furnace numbers, varieties, specifications and materials. The same material rack or stack can not store stainless steel pipes with the same specifications or similar material shapes and different furnace numbers.
To avoid bending or pipe damage, the stainless steel pipes (or bundles) should be placed on the sleepers at the proper intervals and on the same level to ensure that one end of the stainless steel pipe is aligned.
Stainless steel pipes, which are cold rolled, cold drawn or annealed, can not be stored in open air. If the storage conditions are limited, and outdoor storage is needed, appropriate protective measures should be taken to prevent corrosion of rainwater, snow and fog, and dust pollution.
In the transport, transport compartment to keep clean and free of stones, bricks and other hard objects, in order to avoid the Luo injured stainless steel pipe. For bulk or bundled stainless steel pipes, the sleepers should be cushions at the bottom of the carriage. For vehicles that use steel brackets with flat cars, we must install protective rubber pads on the sides of stainless steel pipes.
When the stainless steel pipe or pipe bundle is transshipped in the factory area, the isolation sleepers should be properly placed, and at least two places are placed along the length of the steel pipe. The padding wood should be placed perpendicular to the steel pipe and up and down right. The pads should be placed horizontally and well.
The finished stainless steel pipe, delivered for long distance transportation, should be tied firmly after loading. If the wire rope or similar hard material is used, the protective isolator on the steel pipe binding or the protective isolation on the wire rope should be added to avoid the damage to the surface of the stainless steel pipe and prevent the direct collision between the stainless steel pipe and the carriage. Friction and front and back move.
To avoid damage to the steel pipe in the process of bundling and transportation, we must maintain consistency in binding. The same bundle of steel pipes should not be mixed with furnaces and steel pipes if they are the same as those of the furnace number, the same steel grade and the same specification. The weight of each bundle of stainless steel pipes should not be more than 50 kilograms. The weight can be increased by the user’s consent, but the heaviest weight should not be greater than 80 kilograms. For the flat end stainless steel pipe bundling, one end should be kept aligned, the difference between the end of the pipe end is less than 20mm, the length difference of each bundle of stainless steel pipe is less than 10mm, but the length difference of each bundle of steel pipe which is ordered according to the usual length is less than 5mm, and the longest and the secondary length of a bundle of steel pipes is not more than 10mm.
When the stainless steel pipe is put into the container, the cardboard, plastic cloth or other moistureproof material should be placed on the inner wall of the container. The container must be kept tight without water seepage. For stainless steel pipe with container packing, a sign should be attached to the container. The corresponding signs should be hung on the outer end of container. If the stainless steel pipe has special packaging requirements, it shall be agreed by the supplier and the buyer.
When loading stainless steel pipes, in order to avoid depression, indentation, scratching, and pipe damage, a steel wire rope with a disk crane, a nylon belt or a protective isolator should be used during loading. It is not allowed to pull out the nylon belt or the wire rope under the pressure of the steel pipe or the pipe bundle. When loading stainless steel pipes for automobile transportation, the nylon belt or wire rope must be kept stable when the loading conditions are restricted, in order to prevent the strong collision or roll between the stainless steel pipes or the bundles and the barbarous loading and unloading.
For the marking of packing, each bundle of stainless steel pipes wrapped in bundles should be hung on each end of the steel pipe with 1 signs. The stainless steel pipe packed in the container shall be hung in and out of the container with 1 signs, indicating the name of the product, the contract number, the model, the furnace number, the steel grade, the bundle number, the weight, the length, the count and the date.
In the package case, we must have the product inspection certificate or material analysis report. If medium and small steel, wire rod, steel bar, steel steel pipe, steel wire and wire rope, etc., it can be stored in a well ventilated material shed, but must be on the mat. Second, there are some small stainless steel, thin steel plate, steel strip, silicon steel sheet, small diameter or thin wall steel pipe, all kinds of cold rolled and cold drawn steel.
Materials and metal products with high price and corrosion resistance can be put into storage. Third the warehouse should be selected according to the geographical conditions, usually use the ordinary closed storeroom, that is, the roof has a wall, close doors and windows, with a ventilation system. Fourth, do not stack with corrosive materials such as acid, alkali, salt and cement in warehouses.
Different varieties of steel should be stacked separately, so as to prevent confusion and prevent contact corrosion. Fifth, large scale steel, rail, steel plate, large diameter steel pipe and forgings can be stacked in open air. The site or storehouse for stainless steel pipe should be selected in a clean and well drained place, away from factories and mines that will generate harmful gases or dust. Weed and all kinds of sundries should be cleared on the site to ensure that the stainless steel is clean. The requirement for storehouse is clear and ventilated, rainy days can be closed to prevent dampness, and often keep proper storage environment.
