Storage Of Large Diameter Anti-corrosion Straight Seam Steel Pipe

Today to tell you how to save Large diameter anti-corrosion longitudinally submerged arc welding pipeipe:First, keep the warehouse clean and strengthen the material maintenance

1. After the surface of the general steel pipe is removed from the net, it is not necessary to apply oil, but for high-quality steel, alloy steel plate, thin-walled pipe, alloy steel pipe, etc., after the rust is removed, the inner and outer surfaces need to be coated with anti-rust oil before storage.2. Before the storage, the materials should be protected from rain or impurities. For materials that have been rained or soiled, they should be cleaned according to their properties. For example, high-strength wire brush, low-hardness cloth, Cotton and other things.3. the material should be checked frequently after storage, if there is rust, the rust layer should be removed.

Second, choose the appropriate venue and warehouse

1. The warehouse needs to pay attention to ventilation on sunny days, and pay attention to closing the moisture on rainy days, and always maintain a suitable storage environment.2. The site or warehouse where the steel pipe is to be stored should be cleaned and drained, away from the factories and mines that generate harmful gases or dust. Weeds and all debris should be removed from the site to keep the steel pipe clean.3. in the warehouse should not be stacked with acid, alkali, salt, cement and other materials that are corrosive to steel pipes. Different types of steel pipes should be stacked separately to prevent confusion and prevent contact corrosion.4, large-scale steel, rail, insult steel plate, large diameter steel pipe, forgings, etc. can be stacked in the open air.5. small and medium-sized steel, wire rod, steel, medium-diameter steel pipe, steel wire and wire rope, etc., can be stored in a well-ventilated shed, but must be placed on the underside.6. Some small steel pipes, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steel pipes, and high-priced, corrosive metal products can be stored in the warehouse.7. The warehouse should be selected according to the geographical conditions. Generally, the general closed warehouse is used, that is, there is a warehouse with a wall, a strict door and window, and a ventilation device.

Third, reasonable stacking, advanced first release1. Open-air stacking angle steel and channel steel should be placed downside, that is, the mouth should face downward, the I-beam should be placed vertically, and the I-groove surface of the steel pipe should not face upwards, so as to avoid the stagnant water. The open-pit stacking angle steel and channel steel should be lowered, that is, the mouth Downward, the I-beam should be placed upright, and the I-groove surface of the steel pipe should not face upwards to prevent the water from rusting.2. open-air stacking angle steel and channel steel should be placed down, that is, the mouth is facing down, the I-beam should be placed vertically, the I-groove surface of the steel pipe should not face upwards, so as to avoid the principle that the stagnant water accumulation of the water is stable and secure. Under safe conditions, the products should be palletized according to the variety and specifications, and the materials of different varieties should be separately palletized to prevent confusion and mutual corrosion.3. It is forbidden to store items that are corrosive to steel pipes near the niobium.4. The bottom of the raft should be high, strong and flat to prevent the material from being damp or deformed..5. The same kind of materials are stacked separately according to the warehousing, which is convenient for implementing the principle of advanced first-time.6. For the steel stacked in the open air, there must be wooden mats or strips underneath. The rake face is slightly inclined to facilitate drainage, and the materials should be placed flat to prevent bending deformation.7. Stacking height, manual operation does not exceed 1.2m, mechanical operation does not exceed 1.5m, and width is not more than 2.5m.8. There should be a certain passage between the? and?, and the inspection road is generally O. 5m, access channel depends on material size and transportation machinery, generally 1.5~2. Om.9. The bottom of the raft is high. If the warehouse is a cement floor facing the sun, the height is O. 1m can be; if it is mud, it must be high. 2 to 0.5 m. If it is an open space, the cement floor height is O·3?O·5m, and the sand surface is 0.5~O. 7m.

Fouth, packaging of Protective Materials and Preservatives or other plating and packaging applied before leaving the factory. This is an important measure to prevent corrosion of materials. It must be protected during transportation and handling, and can not be damaged. the term.
