摘要: Extruded pipes of thermoplastically processable polymers are wound cold around a mandrel and thereafter subject to thermal fixing. During or before winding, the pipe is twisted in a direction opposite to that of the helix formation, about its longitudinal axis, preferably through angles of 5.degree. to 360.degree. per coil. The resilience of the coiled pipe is surprisingly improved to the point where the resilience factor R approaches 1.0.

摘要: A multilayer polymer hose or pipe conduit which contains at least one barrier layer of polyester, which acts as a barrier to fuel being carried thereby. In a preferred form of the invention, the hose or conduit has an inner polyamide protective layer, an outer polyamide protective layer, an adhesion promotor layer between the barrier layer and the inner protective layer, and another adhesion layer between the barrier layer and the outer protective layer.
