Polyurethane pipes are widely used in industrial fluid transportation, pneumatic systems, and machinery manufacturing due to their excellent wear resistance, chemical corrosion resistance, and flexibility. Proper operation of polyurethane pipes not only extends their service life but also ensures efficient and stable system operation.
Before using polyurethane pipes, select the appropriate specifications and models based on specific working conditions, ensuring that the pipe's pressure rating, temperature range, and chemical compatibility meet requirements. During installation, avoid excessive bending or twisting; the recommended minimum bending radius is typically 4 to 6 times the pipe diameter to prevent damage to the pipe wall or internal structure. Connection methods can be selected according to actual needs, such as crimping, flaring, or quick couplings, ensuring a secure seal at the connection to prevent leakage.
During operation, polyurethane pipes should avoid contact with sharp objects or rough surfaces to prevent scratches that could degrade performance. If used in high-pressure systems, gradually increase the pressure and check for abnormal expansion or leakage in the pipe body. When used in high-temperature or low-temperature environments, pay attention to the pipe's temperature limit; prolonged exposure to excessive temperatures may cause the material to harden or become brittle, affecting its service life.
For maintenance, it is recommended to regularly inspect the appearance of the tubing. If cracks, bulges, or accelerated wear are found, it should be replaced promptly. Use a neutral detergent for cleaning, avoiding contact with strong acids or alkalis. When storing, polyurethane tubing should be laid flat in a dry, well-ventilated place, away from heat sources and direct sunlight. Maintain appropriate tightness when coiling to prevent long-term deformation from compression.
Proper operation and maintenance of polyurethane tubing can significantly improve its durability and reliability, and reduce system maintenance costs. When promoting such products, foreign trade professionals should clearly explain the operating procedures to customers to ensure end-users receive the best user experience.
