Conduit for transporting pressurized warm fluid in internal combustion engine of car has series of indents, placed on outer surface of each bend, that deform due to inner pressure and heat

摘要

Conduit (1) has series of indents (2) placed on outer surface of each bend (10, 11), and projecting towards inside of conduit. Indents are deformed due to internal pressure inside conduit, and due to softening of material caused by heat of fluid. This deformation increases effective length of outer wall of conduit.
