Abstract
A sealed flange joint for high pressure and/or high purity fluid channels includes a first flange with a first fluid channel and a cylindrical front cavity. The front cavity is axially delimited by a ground surface and radially by a peripheral surface. The first fluid channel passes axially through the first flange to open into the ground surface. A polymer seal ring has a radial outer surface and a radial inner surface, and is fitted into the cylindrical front cavity so that its radial outer surface engages the peripheral surface of the front cavity. A second flange is removably fixed onto the first flange, and has a second fluid channel in axial continuation of the first fluid channel. The second flange has an axially protruding cylindrical front nipple with a conical head, the second fluid channel axially opening into an end surface of the conical head. The conical head engages the radial inner surface of the seal ring to radially press the latter with its radial outer surface against the peripheral surface of the front cavity.
