The charging hose is a type of plastic tube with three different colored layers, commonly used for identification and differentiation of different piping systems or cable bundles. These layers not only facilitate easy recognition but also enhance its structural stability. It possesses excellent chemical resistance, heat resistance, and impact resistance, and is widely applied in industrial, construction, and electrical fields, such as chemical plant installations, high – rise building wiring, and electrical equipment assembly.
1. Sanitary Safety: The inner layer material conforms to the national drinking water sanitary standard, ensuring the safety of water quality during long-term use.
2. High Durability: The middle layer of fiber-reinforced material significantly enhances the pipe’s resistance to pressure and impact, extending its service life.
3. Wide Temperature Range: The outer layer of weather-resistant polyethylene material can be used stably within a temperature range of -40℃ to 95℃, adapting to extreme climatic conditions.
4. Easy Installation: The charging hose has good flexibility and memory, facilitating bending installation, reducing the use of joints, and lowering the risk of leakage.
5. Energy-Efficient and Efficient: The smooth inner wall reduces fluid resistance, lowering energy consumption during the transportation process.
6. Environmentally Friendly and Recyclable: All materials are recyclable, meeting environmental standards, and reducing the impact on the environment.
Chemical resistance: The charging hose can resist the corrosion of many chemical substances, suitable for a variety of industrial environments.
Heat resistance: can withstand high temperatures, generally used in the range of-40℃ to 100℃. Impact resistance: has good impact resistance, not easy to rupture or deformation.
Flexibility: The charging hose has certain flexibility, easy to install and bending.
Insulation: has good insulation performance, suitable for electrical applications.
