The radiator water pipe is the core channel of the cooling/heating system, responsible for transporting heat medium or coolant, conducting heat to the heat dissipation end and returning it, and some also need to be diverted to components such as warm air. High quality water pipes are made of EPDM rubber or seamless steel pipes, with uniform wall thickness and precision molding. The interface is tightly sealed, with a pressure resistance of ≥ 1.0MPa, and can withstand temperature differences of -40 ℃~150 ℃. They are also corrosion-resistant and aging resistant.
