A system for sealing a plurality of orifices through a wall of a vessel is provided. The system includes a plurality of sealing members configured to releasably seal respective orifices of the plurality of orifices. The system also includes a base defining a central axis therethrough. The base includes a plurality of segments disposed about the central axis. Each of the plurality of segments includes an outer surface and an inner surface. The inner surface is configured to engage at least one sealing member of the plurality of sealing members. Further, each segment of the plurality of segments is configured to deform toward the central axis on application of a force upon the outer surface thereof to bias the at least one sealing member into sealing engagement with a respective orifice of the plurality of orifices.

A method of remanufacturing a shell of a heat exchanger is provided. The shell has an inner surface that defines an inner diameter thereof and the inner surface has a worn portion adjacent to an end of the shell. The method includes machining the inner surface to remove the worn portion and machining to form a tapered surface adjacent to the end of the shell. A diameter of the tapered surface increases progressively from the inner diameter of the shell to a maximum diameter at the end of the shell.

Method of remanufacturing a shell of a heat exchanger and a remanufactured shell

A device for sealing one or more orifices on a vessel for pressurizing fluid is provided. The device includes an outer surface and an inner surface. The inner surface includes one or more substantially semi-spherical protrusions corresponding to the orifices. The protrusions are configured to contact with edges of the orifices and seal the orifices.
