The transportation and storage of polyurethane lined steel pipes requires several issues to be aware of to ensure their quality and safety. Here are some things to look out for::
1. Transportation: During transportation, appropriate protective measures should be taken to avoid impact, extrusion, scratches and other damage to the lined polyurethane steel pipe. At the same time, it is necessary to keep the steel pipe dry and clean to prevent moisture and dirt. In the process of loading and unloading, it should be handled with care and avoid using sharp tools, so as not to damage the anti-corrosion layer and insulation layer of the steel pipe.
2. Storage: During storage, the lined polyurethane steel pipe should be placed in a dry, cool and well-ventilated place to avoid direct sunlight and high temperature. At the same time, it is necessary to stay away from acids, alkalis, salts and other chemicals to avoid corrosion of steel pipes. When the storage time is long, regular inspection and maintenance should be carried out to find and deal with problems in time.
3. Temperature and humidity control: During storage, the temperature and humidity should be controlled to avoid the impact of too high or too low temperature and humidity on the steel pipe. Especially in a humid environment, appropriate moisture-proof measures should be taken, such as placing desiccant, regular ventilation, etc., to keep the steel pipe dry and clean.
4. Stacking method: In the process of storage and stacking, attention should be paid to the stacking method, maintain a stable stacking height and angle, and avoid excessive pressure and twisting on the steel pipe. At the same time, it is necessary to keep the steel pipe clean and dry to prevent dust and dirt accumulation.
5. Anti-corrosion treatment: If the steel pipe needs to be stored or transported for a long time, anti-corrosion treatment should be carried out, such as anti-rust paint, wax, etc., to enhance the anti-corrosion ability of the steel pipe. At the same time, proper cleaning and treatment should be carried out before use to ensure the quality and safety of steel pipes.
