Spiral pipes are stacked outdoors, and most of them are buried underground when in use, so they are easy to corrode and rust. In order to ensure the smoothness of the pipeline, spiral pipes are required to have strong corrosion resistance.
1. Anti corrosion failure; When the pipeline is erected, the anti-corrosion work shall be done well or the anti-corrosion spiral steel pipe shall be directly used. The reason for the corrosion of the pipeline is that the anti-corrosion coating of the pipeline has been damaged. Once the anti-corrosion coating is separated from the pipeline surface, it will naturally cause anti-corrosion failure. This is also ladder type. We should choose anti-corrosion spiral pipe when purchasing spiral pipe.
2. Influence of external conditions; It mainly depends on the characteristics and temperature of the medium around the pipeline and whether the medium around the pipeline is corrosive. Because the corrosivity of the medium is closely related to the microorganisms contained in the soil. And if it is a long-distance pipeline, the soil environmental properties are more complex. In addition, the temperature of the environment where the pipeline is located will also affect the corrosion of spiral pipes. If the temperature is high, the corrosion speed will be faster, while if the temperature is low, the corrosion speed will be slower.
1. Small and medium-sized section steel, wire rod, reinforcement, medium diameter steel pipe, steel wire and steel wire rope can be stored in a well ventilated shed, but they need to be covered and padded.
2. Some small steel, steel sheet, steel strip, silicon steel sheet, small-diameter or thin-walled steel pipe, all kinds of cold-rolled and cold drawn steel and metal products with high price and easy corrosion can be stored in the warehouse.
3. The site or warehouse for the storage of spiral steel pipe products should be in a clean and unobstructed place, away from factories and mines that produce harmful gas or dust. Weeds and all sundries shall be cleaned on the site to keep the steel clean.
4. Large section steel, steel rail, steel plate, large-diameter steel pipe, forgings, etc. can be stacked in the open air.
5. It is not allowed to stack with acid, alkali, salt, cement and other materials that are corrosive to steel in the warehouse. Different types of steel shall be stacked separately to prevent confusion and contact corrosion.
6. The warehouse shall be selected according to the geographical conditions. Generally, the ordinary closed warehouse is adopted, that is, the warehouse with roof, enclosure, tight doors and windows and ventilation devices.
7. The warehouse is required to pay attention to ventilation in sunny days, close to moisture in rainy days, and often maintain a suitable storage environment.
