Abstract
Abstract The disclosure is directed to a structure for mounting a cylindrical nozzle body on a pressure vessel body having an internal lining for corrosion resistance or other purposes, said nozzle body being of a material which cannot be welded to the pressure vessel body. The nozzle body is provided with a flange of recessed portion at its leading end directed into the pressure vessel, a stepped portion for abutment against a seating surface of the pressure vessel body at its periphery behind the recessed portion and a threaded portion for securing the nozzle body to the vessel at a periphery thereof rearwardly of the recessed portion.
