Instrument penetration for high pressure vessels

摘要

A connector assembly and an installation method therefor provides a fluid-tight joint between a nozzle and a column concentrically supported within the nozzle. An annular seal assembly is disposed above a flange formed on the interior of the nozzle. A spacer sleeve is threaded to the nozzle for engagement with a ledge formed on the column. A clamp assembly is mounted to the column at a fixed position and includes means for raising the column in relation to the nozzle to fix the axial position of the column. A nut threaded to the column is rotatable for forcing a drive sleeve into compressive engagement with the seal assembly to produce a fluid-tight seal between the column and the nozzle.
