Contoured Barrel Nozzles
A contoured barrel nozzle has the bottom of the barrel contoured to match the ID of the shell or head of a pressure vessel. Based on the customer specified radius and wall thickness of the pressure vessel, our design group will produce a manufacturing print to match that of your pressure vessel. During the fabrication assembly, the nozzle gets inserted into a precut hole inside the shell or head and welded directly to the ID of a pressure vessel, forming a one weld integral connection. This nozzle design does not allow for any internal projection. Although, this is a more expensive alternative to the flat bottom attachment type, it eliminates hours of grinding of extra material to get it flush with the ID of a pressure vessel.
