(57) Abstract :
A sealed flange joint for high pressure and/or high purity fluid chanaek tt^n-i prises a first flange (10) with a first fluid channel (12)
and a cylindrical front cavity (14). The front cavity (14) is axially delimited* by a ground surface (18) and radially by a peripheral
surface (20). The first fluid channel (12) passes axially through the first flange (10) to open into the ground surface (18). A polymer
seal ring (30) has a radial outer surface (32) and a radial inner surface (34), and is fitted into the cylindrical front cavity (14) so that its
radial outer surface (32) engages the peripheral surface (20) of the front cavity. A second flange (16) is removably fixed onto the first
flange (10), and has a second fluid channel (22) in axial continuation of the first fluid channel (12). The second flange (16) has an
axially protruding cylindrical front nipple (24) with a conical head (26), the second fluid channel (22) axially opening into an end
surface (28) of the conical head (26). The conical head (26) engages the radial inner surface (34) of the seal ring (30) to radially press
the latter with its radial outer surface (32) against the peripheral surface (20) of the front cavity (14).
