Abstract

A seal joint is for an arrangement for separating a gas and liquid mixture having a vessel with an inlet for entry of the gas and liquid mixture and an outlet for exit of a separated gas, and a centrifugal separation cyclone in the vessel for centrifugally separating the gas from the mixture. The joint requires the vessel to have an internal vessel flange defining a flange opening. An inlet tube extends into the flange opening. A first retaining ring having a first outer ring which engages the flange, also has a first inner ring portion extending around the inlet tube in the flange opening. A second retaining ring has a second outer ring engaged with the flange and a second inner ring extending around the inlet tube in the flange opening. An O-ring is engaged around the inlet tube and between the first and second inner rings and fastening bolts are use for fastening the first and second outer rings to the flange, around the flange opening for deforming the O-ring against the inlet tube.
