## Abstract

Machine for forming, by means of a pressurized fluid, and for profiling, by means of profiling tools, a metal tubular product, for instance a pipe, in one and the same work cycle, in particular for forming a tubular product in two different portions thereof by using one injector only and forming the tubular product in two different non-adjacent portions by using two injectors.

## Claims

### Claim 1

A machine for forming and profiling a metal tubular product, for instance a pipe, by means of pressurized fluids and profiling tools comprising a fluid-dynamics control unit, a pusher configured and arranged for pushing the metal tubular product, vise, a mold configured and arranged for determining the desired profile of the metal tubular product through a forming process, at least a fist injector and a second injector provided with at least one battery of profiling tools wherein the first injector is provided with at least two radial channels and at least two retractable gaskets that are self-centering during its expansion step, the second injector in a position specular with respect to the first injector provided with one radial channel only and one gasket only, or alternatively two radial channels and two joints.

### Claim 2 (depends on 1)

A machine for forming and profiling a metal tubular product, for instance a pipe, according to claim 1, wherein the fluid-dynamics control unit with means configured and arranged for feeding each injector with fluids at different pressures whenever they are both provided with two gaskets with fluids at different pressures.

### Claim 3

A machine for forming and profiling a metal tubular product, for instance a pipe, according to any of the previous claims, wherein the battery of profiling tools is placed next to at least one of the injectors.
