ABSTRACT:
Clamps and clamping systems for sealing the interface between two generally tubular conduits are disclosed. The clamps of the present invention are especially well adapted for use in nuclear reactor systems, especially as clamps for the instrument port interfaces of nuclear reactors. The clamps are generally comprised of articulated members pivotally joined by link plates such that the clamp may be opened in jaw like fashion so as to allow easy assembly around the conduits to be sealed. The conduit seal assembly includes an upper positioner which has a frusto-conically shaped surface and a male flange with a frusto-conically shaped upper surface. These two surfaces create an annular wedge-like opening for accepting a wedge-shaped upper clamp. The upper articulated clamp when assembled thus provides the proper clamping force between the conduit seal and male flange.
