There are some ways to store stainless steel pipe(ss pipe
1. Choose the appropriate venue and warehouse
1) Storage of stainless steel pipe for the site or warehouse should be selected in a clean, drained place, away from the production of harmful gases or dust factories and mines. On the venue to remove weeds and all debris, keep the steel clean.
2) In the warehouse, it is forbidden to pile up the materials which are corrosive to the stainless steel pipe with acid, alkali, salt and cement. Different varieties of stainless steel pipes should be stacked separately to prevent confusion and prevent contact with corrosion.
3) Large steel, rail, shame steel, large diameter steel pipe, forgings, etc. can be piled open.
4) Small and medium sized steel, wire rod, steel bar, medium caliber steel pipe, steel wire and wire rope, etc., can be stored in well-ventilated shed, but must be on the mat.
5) Some small steel, sheet steel, steel, silicon steel, small diameter or thin-walled stainless steel tube
, a variety of cold-rolled, cold drawn steel and high prices, corrosion-resistant metal products, can be stored in storage.
6) Treasury should be selected according to geographical conditions, the general use of ordinary closed warehouse, that is, a roof with walls, doors and windows, with ventilation device warehouse
7) Treasury requires sunny days to pay attention to ventilation, rainy days to turn off moisture, often maintain a suitable storage environment.
2. Reasonable stacking, advanced first
1) The principle of stacking is that under the conditions of stable palletizing and ensuring safety, the palletizing can be done according to the variety and specification, and the materials of different varieties should be stacked separately to prevent confusion and mutual corrosion.
2) It is forbidden to store items that have a corrosive effect on steel in the vicinity of the pile.
3) Bottom should be padded, strong, flat, to prevent moisture or deformation of the material.
4) The same materials have been stacked separately according to warehousing, to facilitate the implementation of the principle of first-mover.
5) Open piled steel, the following must have a wooden pad or stone, butt slightly tilted, to facilitate drainage, and pay attention to the material placed straight to prevent bending deformation.
6) Stacking height, manual work of no more than 1.2m, mechanical work no more than 1.5m, stack width does not exceed 2.5m.
7) Between the stack and stack should leave some channels, check the road is generally 0.5m, access channels, depending on the size of the material and transport machinery may be, usually 1.5 ~ 2.0m.
8) Stack bottom padding, if the warehouse is a sunny cement floor, padded 0.1m can be; if mud, to be padded 0.2 ~ 0.5m. If the open space, the cement floor padded 0.3~0.5m, sand mud pad high 0.5 ~0.7m.
9) Open storage of angle steel and channel should be put down, that is, mouth down, I-beam should be placed, steel I slot surface can not be up, so as not to accumulate water rust.
3. Protective material packaging and protective layer
Pre-painted stainless steel pipe factory preservatives or other complex coating and packaging, which is an important measure to prevent corrosion of materials in the transport process must pay attention to the protection, can not be damaged, extend the shelf life of the material.
4. Keep the warehouse clean and strengthen material maintenance
1) Stainless steel pipe material before storage should be taken to prevent rain or mixed with impurities on the already stained or rainy materials according to their nature by a different method of wiping, such as high hardness available wire brush, low hardness Cloth, cotton and other objects.
2) After the stainless steel pipe material storage should be checked regularly, if rust, rust layer should be removed.
3) After removing the net surface of the general steel, do not oiled, but on the high-quality steel, alloy steel plate, thin-walled stainless steel pipe, alloy steel pipe, rust and rust on both the inner and outer surfaces are coated with anti-rust oil and then stored.
4) The more serious corrosion of stainless steel pipe, rust should not be long-term custody, should be used as soon as possible.
