Abstract:
A segmented coupling device for coupling two pipe elements selected from the group consisting of two plain-ended sections of pipe; and one plain ended section of pipe and a pipe fitting, the segmented coupling comprising a plurality of arcuate coupling segments, each of the arcuate coupling segments including:a successive series of circumferentially discontinuous teeth extending radially inward along the interior arcuate surface of the coupling segment;each of the teeth including end sections and a central, radially innermost flat section;the flat sections of the successive series of teeth providing a plurality of circumferentially discontinuous and spaced gripping surfaces for securely engaging at least one plain ended pipe section without cutting into the pipe exterior;and each arcuate coupling segment having means for being detachably attached to at least one other adjacent arcuate coupling segment in surrounding relationship around an outer circumference of the abutting ends of the two pipe elements to be coupled.
