  • Flexible element with integral outer shield and/or inner liner
    Patent number: 8690195
    Abstract: A flexible bellows used in a pipe coupling includes composite convolutions having integral extensions forming one or both of an outer shield or inner liner to enhance performance of the coupling. Embodiments incorporate dampers, hangers and convolution modifications. Various embodiments are disclosed.
    Type: Grant

  • Angled flexible coupling with integral outer shield and/or inner liner
    Patent number: 8424922
    Abstract: A flexible bellows used in a pipe coupling includes composite convolutions having integral extensions forming one or both of an outer shield or inner liner to enhance performance of the coupling. Embodiments incorporate asymmetric convolution forming discs providing for static angled couplings to accommodate offset or misaligned pipe system components.

  • Sealed flexible coupling with torsion acceptance
    Patent number: 8042840
    Abstract: A coupling has respective support elements extending respectively from each coupling end toward the other, but not directly connected to each other. Radially oriented ends of these elements define a pocket capturing a cushion therein. A non-metallic bellows operably covers the coupling. An optional thermal shield is disposed between the bellows and the support element.

  • ADJUSTABLE TUBULAR NVH DAMPER AND TORSION ABSORBER
    Publication number: 20090283357
    Abstract: Respectively tapered and threaded pipe ends are rotated respective to each other to connect the pipe ends and progressively compress a yieldable damper sleeve therebetween as the pipes are rotated. NVH and torsional forces from one pipe end to another are suppressed.

  • Flexible liner air gap pipe
    Publication number: 20050011573
    Abstract: A multiple wall air gap pipe includes a rigid tube wall and at least one flexible tube wall defined by two or more overlapping profiles in wound, interlocking configurations. The multiple wall air gap pipe can be bent on conventional single wall pipe bending apparatus, inexpensively, while retaining the benefits of multiple wall air gap pipes.
