Device and method for connection with relative and controlled sealing between a pipe and a ceramic tube

A device for connection with relative and controlled sealing between a pipe (1) and a ceramic tube (7) comprising:

• a cylindrical chamber (5) that is attached in a sealed manner to said pipe, whereby one end of the ceramic tube is placed inside said chamber,
• a seal comprising at least two sets of sealing fixtures (3, 3′) placed in the annular space between the ceramic tube and the chamber,
• a crosspiece (4) interposed between the two sets of sealing fixtures (3, 3′),
• a flange (6) for applying longitudinal pressure to a compression ring in the form of a flange (6) for compressing the sealing fixtures (3, 3′), the compression ring (4′) applying longitudinal pressure to one set of sealing fixtures (3′) which compress against the crosspiece (4), the crosspiece (4) applying longitudinal pressure against the other set of sealing fixtures (3) that compress with respect to the housing (5), and
• an injector arrangement (8) for injection of a fluid between the two sets of sealing fixtures (3, 3′) so as to apply a pressure differential that is determined on each of the fixtures (3, 3′).
