Process for the formation of a tubular element of plastic material with a metallic tubular element, characterized in that it consists in introducing a tubular pre-split piece into the tubular element, constituted by a fibrous material treated by a resin; in applying an externally acting fluid pressure to the interior of the blank, the pressure being greater than that which the metallic element can resist without deteriorating; in simultaneously applying a pressure of internally acting fluid to the exterior of the casing, to compensate the internal pressure, and to heat by a fluid in order to harden the resin.
