Two-phase connector

A fluid connection system for connecting two two-phase flexible pipes each comprising two coaxial casings defining a central flow flowing into an inner casing and an annular flow flowing into a space between the inner casing and an outer casing, the connection system comprising:

• a first complementary connector and a second complementary connector;
• wherein the second complementary connector is configured to be attached to an end of a first two-phase flexible pipe of the two two-phase flexible pipes, and the first complementary connector is configured to be attached to an end of a second two-phase flexible pipe of the two two-phase flexible pipes, the first complementary connector and the second complementary connector having a locking mechanism for locking the first complementary connector and the second complementary connector together in an axial direction;
• wherein the first complementary connector has:
• a central connecting part having a distal end configured to ensure a sealed connection with an end of the inner casing of the second two-phase flexible pipe;
• and
• a peripheral connecting part having a distal end configured to ensure a sealed connection with an end of the outer casing of the second two-phase flexible pipe, the peripheral connecting part having an annular front inner flange, axially traversed by ports opening into a peripheral flow region;
• wherein the central connecting part and the peripheral connecting part are assembled to define a transverse coupling surface;
• and
• wherein the second complementary connector has:
• a central connecting part having a distal end configured to ensure a sealed connection with an end of the inner casing of the first two-phase flexible pipe;
• and
• a peripheral connecting part having a distal end configured to ensure a sealed connection with an end of the outer casing of the first two-phase flexible pipe, the peripheral connecting part having an annular front inner flange, axially traversed by ports opening into the peripheral flow region;
• wherein the central connecting part and the peripheral connecting part are assembled to define a second transverse front coupling surface;
• and
• wherein the central connecting part of the first complementary connector comprises an inner sleeve extended by a disc shoulder and a coaxial tubular outer sleeve having a plurality of axial threaded holes, the inner sleeve and the coaxial tubular outer sleeve being configured to enclose the end of the inner casing of the second two-phase flexible pipe.
