ABSTRACT:
The present invention relates to a conduit system comprising a plurality of conduit elements wherein adjacent conduit elements may be connected together by a coupling means in flexible yet fluid tight fashion. This coupling means may provide a fluid-tight joint despite variations of temperature to which the conduit elements may be subjected. The conduit system may be conveniently used for joining conduits used for feeding water to the turbines of hydro-electric plants. The coupling means may comprise annular rings or flanges fixed on the periphery of each of the pipe ends to be joined together, the annular rings having upwardly and inwardly extending side walls. An annular-type gasket formed of a resilient material may be positioned around the periphery of the rings (e.g. in a bridging relation with same), the annular gasket being positioned in a substantially co-axial alignment with the longitudinal axis of the conduits. The coupling means may also comprise ring clamp means having at least two clamp elements positionable around the annular rings. The clamp elements are provided with a flange receiving channel or groove. With the clamp elements secured about the flanges the gasket member may be radially compressed between the flanges and the clamp means for a fluid tight joint.
