ABSTRACT:
A system for seating at least one gasket member used to seal a pressure vessel penetration where a column penetrates therethrough includes a tubular member, a column which penetrates through the tubular member in a telescoping manner and is normally movable axially relative to and in axial sliding communication with the tubular member before assembly of hardware used to seat the gasket member, and at least one gasket member for sealing the interfaces between the tubular member and the column. The system also includes spacer for filling the axial gap in series with at least one properly seated gasket member between the column and the tubular member and at least one properly seated gasket member when the column cannot be suitably positioned axially relative to the tubular member in order to properly seat at least one gasket member during assembly of hardware utilized to seat at least one gasket member. The system preferably includes a first gauge for testing whether the column can be suitably positioned axially so that at least one gasket member is properly seated during assembly of hardware used to seat the gasket member. The system preferably also includes a second gauge used in conjunction with the first gauge when the column cannot be suitably positioned.
