Matters needing attention in maintenance of straight seam steel pipe

Straight seam steel pipe is a kind of welded steel pipe, which refers to the steel pipe with the welding direction parallel to the longitudinal direction of the steel pipe. After the hot-rolled steel coil is formed by the forming machine, it is converted into a cylindrical shape, using high-frequency current skin effect and proximity effect or arc burning Welding is carried out below the flux layer, so that the edge of the tube blank is heated and melted under a certain extrusion pressure, and finally cooled and formed. It is widely used in my country's petroleum, metallurgy, construction, coal mines, ports, machinery and other industries.

In our lives, straight seam steel pipe products have always played an important role, but how to maintain straight seam steel pipes? Next, let me introduce to you the precautions during the maintenance of straight seam steel pipes!
Choose the right location and warehouse
1. The editor recommends that when storing steel pipes, the site must be clean and dry to avoid placing harmful gases and dust in the factory. If there are weeds and debris that need to be cleaned, the steel pipes must always be kept clean.
2. If they are different types of steel pipes, they should be separated. Corrosive substances such as acid, alkali, salt, cement, etc. should not be piled up on the steel pipe to prevent confusion and corrosion.
3. Steel pipes can also be stored in open places, such as large section steel, steel rails, faded steel plates, large diameter steel pipes, forgings, etc.
4. If it is some small steel pipes, steel plates, steel strips, silicon steel plates, small or thin-walled steel pipes, various cold-rolled and cold-drawn steel pipes, and expensive corrosion-resistant metal products, they can be stored directly without too many taboos.

5. Choose a warehouse based on its geographical location. Warehouses are usually closed, that is, warehouses with roofs, doors and windows. The doors and windows are tightly closed but have ventilation equipment.
Reasonable stacking, first-in-first-out
1. The principle of stacking steel pipes is to stack them under stable and safe conditions. In order to prevent corrosion between products due to confusion, they should be stacked separately according to varieties and specifications.
2. In order to prevent the corrosion of straight seam steel pipes, it is recommended not to place corrosive items around the steel pipes.
3. When storing steel pipes, the bottom of the pile should be built relatively high, solid, and flat to reduce moisture or deformation of the material caused by direct contact between the steel pipe and the ground. The role of the pile is also conducive to drainage.
4. The stacking height of manual operation shall not exceed 1.2 meters, the stacking height of mechanical operation shall not exceed 1.5 meters, and the stacking width shall not exceed 2.5 meters.
5. There should be a certain passage between the chimney and the chimney. The inspection track is usually 0.5 meters, while the approach road depends on the size of the material and transport machinery, usually 1.5 to 2 meters.
The use of preservatives or other plating and packaging before leaving the factory is an important measure to prevent materials from rusting. During transportation, loading and unloading, attention should be paid to protecting straight seam steel pipes to extend their storage period. In addition, everyone must pay attention to keeping the warehouse clean and strengthen material maintenance.
