Abstract: A corrosion-resistant end plate of cladding type for high pressure vessels such as a urea synthesizing tower and ethanol synthesizing equipment includes a cladding member having a curved external surface complementary to the curved internal surface of a cup-shaped solid pressure-resistant member of a suitable thickness for internal pressure. The cladding member is welded as a plurality of divided segments within the cap-shaped solid pressure-resistant member. With the above arrangement, an expensive corrosion-resistant material need not be used as the pressure-resistant member.

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.
