Abstract
A coolant conduit, which is an elongate tubular article for an apparatus requiring cooling by a cooling agent, includes a plurality of layers which are provided by, in combination, discharging a co-axial melt hose, 3D tubing manipulation, and blow molding thereof, each layer of the plurality being composed of a polymeric material which is thermoplastically processable. The plurality of layers preferably includes at least one inner layer which is composed of a polymeric material which is substantially inert to the cooling agent and which is substantially non-swelling; and an outer layer which is composed of at least one polyamide and which has a high pressure resistant which conveys a high bursting strength.
