Process for the manufacture of prestressed concrete pipes, characterized in that an armature of prestressing wire conveniently separated from the inner mold is wound on an expandable inner mold, this winding of the wire being carried out without tension, because the space between the reinforcement and the inner mold is filled with a product capable of setting and hardening, such as cement or concrete, because the inner mold is opened or expanded, so that the load thus introduced is transmitted to the wires of the prestressing reinforcement through said hardenable and hardenable product., before the setting takes place because the space between the reinforcements and the external mold is filled, allowing the assembly to harden and, subsequently, the demolding is carried out by removing the prestressed and set tube.
