Abstract
In a radial flow catalytic reactor, a centerpipe is gravity supported in a central socket member and accommodated as to vertical upward movement within a predetermined maximum distance to prevent unseating of the centerpipe due to thermal cycling of the catalyst and/or the reactor internal members. Such vertical movement of the centerpipe is accommodated by extending the length of the socket member so that it exceeds the expected lift distance of the centerpipe due to such cycling. Desirably, but not necessarily, the centerpipe may include a perforated pipe member axially coextensive with and enclosed within the screen member. The pipe and screen members are independently supported in the socket member by gravity.
