<p>An axial joint system (101; 201; 301; 501) of a plurality of pre-insulated ducts (106; 206; 306) is illustrated, comprising: an annular joint element (102; 202; 302; 402; 502) provided, at its axially opposed parts, with a first (103; 203; 303; 503) and a second (104; 204; 304; 504) perimetral seat, suitable for housing an end portion (105; 205; 305) respectively of a first and a second duct (106; 206; 306) of said plurality of ducts; and fixing means (107; 207; 307; 507) for mechanically fixing the annular joint element (102; 202; 302; 402; 502) to said first and second ducts (106; 206; 306). It is also illustrated a method of axially joining a plurality of pre-insulated ducts (106; 206; 306), as well as a piping comprising a plurality of ducts (106; 206; 306) connected by a plurality of axial joint systems (101; 201; 301; 501).</p> |
