Abstract

A process for the manufacture of hose or tubing conditions plastic high pressure hose having at least one reinforcing layer of steel wires, cords or longitudinal segments thereof. The hose is internally pressurized for a predetermined period of time which provides a residual permanent elongation of at least 0.5% and increases the interior volume by at least 2% upon release of the pressure.
