The use of clamp-type connectors with flat hub faces for flaw-line applications results in undesirable separations between the hub faces in the area of the pressure seal. Tapered hub faces are proposed as a design solution to the seal separation problem and a displacement analysis is presented. The axial symmetry of the problem and the symmetry about the radial plane of the hub faces interface are both utilized in the analysis. The equations resulting from the analysis are incorporated into a FORTRAN computer program allowing parametric studies to be conducted easily. The results from these studies provide a basis for the effective design of the tapered hubs. Finite element analyses of a particular clamp-type connector with flat and then tapered hub faces are conducted for the dual purposes of comparison with the thesis analytical solutions for the same design and detailed examination of the stress levels induced under various loading conditions.
