Issues Needing Focus in the Storage of Straight Seam Steel Pipes
Straight seam steel pipe is a variety of welded steel pipe. Soon after forming a hot-rolled steel coil by a forming machine, the steel coil is transformed into a cylindrical shape. The substantial-frequency current skin impact and proximity result or arc combustion below the flux layer are utilised for welding, so that the edge of the tube blank is heated and melted below a specified extrusion pressure and finally cooled and formed. Straight seam steel pipes can be divided into higher-frequency straight seam steel pipes (ERW Pipe) and submerged arc welded straight seam steel pipes (LSAW Pipe) according to the production procedure. Petroleum, metallurgy, construction, coal, ports, machinery, and so on. The market is broadly utilised in oil and gas transportation, reduced-pressure water fuel transportation, mining fluid transportation, belt conveyors, car drive shafts and other industries.
Longitudinal welded pipe equipment plays an essential role in people's lifestyle and operate. But the maintenance of straight seam steel pipes has constantly been a headache. Let us understand the precautions in the upkeep process.
one). Pick a suitable location and warehouse
1. The spot and warehouse where steel pipes are stored should be clean, cost-free of water, and far away from factories and mines that create harmful gases and dust. Weeds and debris should be eliminated on site to keep steel pipes clean.
2. Do not pile corrosive substances such as acid, alkali, salt, cement, and so on. on the steel pipe in the warehouse. Diverse sorts of steel pipes must be stacked individually to avoid confusion and contact corrosion.
3. Big area steel, rails, faded steel plates, huge diameter steel pipes, forgings, etc. can be stacked in the open air.
4. Modest and medium-sized steel pipes, metal wires, steel wires, medium-diameter steel pipes, steel wires and wire ropes can be stored in a properly-ventilated material shed, but underlays need to be installed.
5. Some small steel pipes, steel strips, silicon steel plates, steel plates, little or thin-walled steel pipes, different varieties of cold-rolled and cold-drawn steel pipes, and higher-priced and easily corrosive metal products can be stocked.
6. Decide on a warehouse primarily based on geographic location.
7. Managing and Leading Using the 2 Core Human Needs The warehouse ought to be ventilated on sunny days, and closed on cloudy and rainy days, and maintain a proper storage atmosphere.
2). Realistic stacking, 1st in initial out
1. The principle of stacking is that under stable and protected stacking problems, it need to be stacked according to types and specs, and distinct sorts of resources ought to be stacked separately to keep away from confusion and mutual corrosion.
two. It is strictly forbidden to retailer content articles corrosive to steel pipes close to the stacking place.
3. The bottom of the pile need to be high, powerful and flat to avoid the materials from being damp or deformed.
4. Similar components are stacked in the purchase of storage, and the principle of first in, initial out is recognized.
5. For section steel stacked in the open, there have to be wooden mats or stone bars beneath, the stacking surface need to be somewhat inclined to facilitate drainage, and consideration must be paid to the flatness of the materials to stop bending and deformation.
6. The stack height for guide operation should not exceed one.2m, the stack height for mechanical operation ought to not exceed 1.5m, and the stack width must not exceed 2.5m.
7. There should be a certain passage amongst the stacks, the width is normally .five meters, and the approach road depends on the size of the supplies and transportation machinery, generally one.5-2 meters.
eight. The bottom is raised, the warehouse is a cement floor, and the height is .1m if it is muddy, it should be filled with .two-.5m. If it is a wilderness, the cement floor is raised by .three-.5m, and the sand and mud surface is raised by .five-.7m.
9. The angle steel and channel steel in the open air environment need to be bent downward, that is, the steel pipe should be downward and erect. The channel surface of the steel pipe must not face upward to avoid the accumulated water from rusting.
3). The packaging and protective layer of protective materials.
The preservatives or other electroplating and packaging utilized by the steel plant before leaving the factory are important measures to avert materials from rusting. In the course of transportation and loading and unloading, care should be taken to defend them to extend the storage period of the supplies.
4). Hold the warehouse clean and strengthen material upkeep.
Primarily as follows:
1. Just before coming into the warehouse, care ought to be taken to avert rainwater from acquiring wet or mixed with impurities, and use different strategies to clean contaminated components in accordance to its performance. For instance, available substantial-hardness steel wire brushes, cloth, cotton, and so forth.
2. The resources must be checked frequently right after storage. If there is rust, please eliminate the rust layer.
three. Following the surface of ordinary steel pipes are cleaned, no oil is required, but the inner and outer surfaces of substantial-good quality steel pipes, alloy steel, thin-walled pipes, alloy steel pipes, etc. must be coated with anti-rust oil.
By way of the above introduction, I believe everyone has a particular knowing and knowing of the precautions in the maintenance approach of ERW straight seam steel pipe.
