1. Occasions that require wear-resistance: Wear-resistant composite steel pipes lined with polyurethane have excellent wear-resistant properties, and are suitable for transporting materials with high hardness and high abrasion, such as transportation pipelines in coal, iron ore, cement and other industries.
2. Occasions that require corrosion resistance: the lined polyurethane material has good corrosion resistance, can resist the erosion of corrosive media such as acid, alkali and salt, and is suitable for transporting corrosive materials, such as the pipeline system of chemical, pharmaceutical and other industries.
3. Occasions that require high or low temperature resistance: The lined polyurethane material can maintain good mechanical properties and stability in high and low temperature environments, and is suitable for occasions that need to transport high temperature and low temperature materials, such as thermal pipelines, cold storage, refrigeration equipment, etc.
4. Occasions that require long life: the polyurethane wear-resistant composite steel pipe lined with polyurethane has a long service life, which can ensure the long-term stable operation of the pipeline, and is suitable for pipeline systems that require long-term operation, such as pipeline systems in mining, electric power, chemical and other industries.
5. Occasions that require flexible connection: the polyurethane wear-resistant composite steel pipe lined with polyurethane can be connected by traditional welding, flange connection, etc., which is convenient for installation and maintenance, and is suitable for pipeline systems that need flexible connection, such as building water supply and drainage, fire protection and other systems.
