<p>PURPOSE: To manufacture a flexible coolant conduit that has high hydrolysis resistance and a high bursting pressure. CONSTITUTION: This flexible coolant conduit comprises a plurality of polymer layers having different compatibility at least at their contact surface. An inner layer 14 is made of a non-swelling material inactive to coolant, and an outer layer 12 is made of a material of a properly selected bursting pressure. The outer layer 12 having a high bursting pressure occupies 25% to 95% in wall thickness of the conduit.</p> |
