Stretchable Elastomeric Tubular Gripping Device

A selectably operable passive gripping device for gripping tubular materials has an elastomeric element which is provided with integrally bonded segmented end rings to prevent the extrusion of the elastomer when it is subjected to high compressive loads. The elastomeric element is molded so that its as-molded gripping surface interferes with the surface of tubular objects to be gripped. The elastomeric gripping element is mounted and supported by a structural element or housing and allows axial flow communication through the gripped tubular objects. The gripping device is used to lift tubular objects such as a tubular string used in oil field applications.
