The materials should be checked frequently after storage
The preservatives or other electroplating and packaging used by the steel plant before leaving the factory are important measures to prevent materials from rusting.3). If it is a wilderness, the cement floor is raised by 0.5m, and the stack width should not exceed 2. The principle of stacking is that under stable and safe stacking conditions, it should be stacked according to varieties and specifications, and different types of materials should be stacked separately to avoid confusion and mutual corrosion.2. It is strictly forbidden to store articles corrosive to steel pipes near the stacking position. Different types of steel pipes should be stacked separately to prevent confusion and contact corrosion. The industry is widely used in oil and gas transportation, low-pressure water gas transportation, mining fluid transportation, belt conveyors, automobile drive shafts and other industries.2.8.2).
The channel surface of the steel pipe should not face upward to prevent the accumulated water from rusting. After the surface of ordinary steel pipes are cleaned, no oil is required, but the inner and outer surfaces of high-quality steel pipes, alloy steel, thin-walled pipes, alloy steel pipes, etc.2.7. Small and medium-sized steel pipes, metal wires, steel wires, medium-diameter steel pipes, steel wires and wire ropes can be stored in a well-ventilated material shed, but underlays must be installed. Reasonable stacking, first in first out1. Choose a suitable location and warehouse1. There should be a certain passage between the stacks, the width is usually 0.3. Some small steel pipes, steel strips, silicon steel plates, steel plates, small or thin-walled steel pipes, various types of cold-rolled and cold-drawn steel pipes, and high-priced and easily corrosive metal products can be stocked.5-2 meters.5-0. Similar materials are stacked in the order of storage, and the principle of first in, first out is realized. must be coated with anti-rust oil.1). During transportation and loading and unloading, care should be taken to protect them to extend the storage period of the materials.5m.Longitudinal welded pipe equipment plays an important role in people’s life and work.4).
Do not pile corrosive substances such as acid, alkali, salt, cement, etc.4. can be stacked in the open air.1m; if it is muddy, it must be filled with 0. The angle steel and channel steel in the open air environment should be bent downward, that is, the steel pipe should be downward and erect.2-0. For section steel stacked in the open, there must be wooden mats or stone bars underneath, the stacking surface should be slightly inclined to facilitate drainage, and attention should be paid to the flatness of the material to prevent bending and deformation.5m, and the sand and mud surface is raised by 0. The place and warehouse where steel pipes are stored should be clean, free of water, and far away from factories and mines that produce harmful gases and dust.3. Keep the warehouse clean and strengthen material maintenance. China Stainless Steel (Alloy) Fittings Suppliers Petroleum, metallurgy, construction, coal, ports, machinery, etc. The stack height for manual operation should not exceed 1. Let us understand the precautions in the maintenance process. The bottom of the pile should be high, strong and flat to prevent the material from being damp or deformed. The bottom is raised, the warehouse is a cement floor, and the height is 0. After forming a hot-rolled steel coil by a forming machine, the steel coil is transformed into a cylindrical shape. If there is rust, please remove the rust layer.5 meters, and the approach road depends on the size of the materials and transportation machinery, usually 1. Weeds and debris should be removed on site to keep steel pipes clean.
The materials should be checked frequently after storage.Mainly as follows:1.7. The high-frequency current skin effect and proximity effect or arc combustion under the flux layer are used for welding, so that the edge of the tube blank is heated and melted under a certain extrusion pressure and finally cooled and formed. The warehouse should be ventilated on sunny days, and closed on cloudy and rainy days, and maintain a proper storage environment.5m. Straight seam steel pipes can be divided into high-frequency straight seam steel pipes (ERW Pipe) and submerged arc welded straight seam steel pipes (LSAW Pipe) according to the production process.6.Straight seam steel pipe is a kind of welded steel pipe.5.3. Choose a warehouse based on geographic 6. Before entering the warehouse, care should be taken to prevent rainwater from getting wet or mixed with impurities, and use different methods to clean contaminated materials according to its performance.2m, the stack height for mechanical operation should not exceed 1. For example, available high-hardness steel wire brushes, cloth, cotton, etc. on the steel pipe in the warehouse.Through the above introduction, I believe everyone has a certain understanding and understanding of the precautions in the maintenance process of ERW straight seam steel pipe.4.7m.9. Large section steel, rails, faded steel plates, large diameter steel pipes, forgings, etc.3-0. The packaging and protective layer of protective materials. But the maintenance of straight seam steel pipes has always been a headache
