The key to the quality of thick-walled steel pipe thickness to the number of uniformity, thick-walled steel pipe wall thickness can not be directly affected by the quality control and use of thick-walled steel pipe, large diameter thick-walled steel pipe is generally used in a variety of mechanical processing, Wall parts processing, thick-walled pipe wall evenly will directly affect the quality of post-processing parts, thick-walled steel pipe wall is not controlled, the overall quality of the steel pipe is not strictly controlled. Choose the appropriate venue and warehouse storage of thick-walled steel pipe of the venue or warehouse, should be selected in a clean place, drain unobstructed, away from the production of harmful gases or dust factories and mines. In the field to clear the weeds and all debris, keep thick-walled steel pipe clean. In the warehouse shall not be with acid, alkali, salt, cement and other thick-walled steel pipe with corrosive materials stacked together. Different types of thick-walled steel pipe should be stacked separately to prevent confusion, to prevent contact corrosion. Large steel, rail, shame plate, large diameter thick-walled steel pipe, forgings, etc. can be open-air pile.
Medium and small steel, wire rod, steel bar, thick-walled steel pipe in the caliber, wire and wire rope, can be stored in a well-ventilated shed, but must be on the next mat. Some small thick-walled steel, thin steel, steel, silicon steel, small diameter or thin-walled thick-walled steel pipe, all kinds of cold-rolled, cold-drawn thick-walled steel pipe and high prices, corrosion-resistant metal products can be stored storage. Treasury should be selected according to geographical conditions, generally use ordinary closed warehouse, that is, the roof has a wall, doors and windows tight, with ventilation of the Treasury. Treasury requires sunny attention to ventilation, rain, close attention to moisture, often maintain the appropriate storage environment. Reasonable stacking, advanced first put the principle of stacking requirements is stable in the palletizing, to ensure safe conditions, so that by species, specifications palletizing, different varieties of materials to be palletizing, to prevent confusion and mutual corrosion, prohibited in the Stacking near the storage of the corrosion of thick-walled steel pipe items, the principle of open-air piled steel, the following must have a wooden mat or stone, a little tilt stack to facilitate drainage, and pay attention to the material placed straight to prevent bending Deformation. Stacking height, artificial work of not more than 1.2m, mechanical operation of not more than 1.5m, stack width of not more than 2.5m. Between the stack and the stack should leave a certain channel, check the road is generally O. 5m, the access channel depending on the material size and transport machinery may be, generally 1.5 to 2. Om. Cushion bottom pad, if the warehouse for the sun's cement floor, pad height O. 1m can; if the mud, to be high O. 2 ~ 0.5m. If the open field, cement floor mat height 0.3 ~ O.5m, sand surface pad height 0.5 ~ O. 7m. Open piling angle and channel steel should be overlooking, that is, mouth down, I-beam should be put up, I thick-walled steel pipe surface can not face up, to prevent water from rusting.
