发明名称 Pipe coupling
摘要 A joint to be used with a coupling tool for coupling first and second axially aligned hubless pipe end sections. The joint includes an outer sleeve and an inner liner disposed within the outer sleeve. A pair of diametrically opposed cylindrically shaped lugs are positioned on the outer surface of the outer sleeve. The axis of each lug is oriented perpendicularly to the longitudinal axis of the outer sleeve for mating engagement with a slot formed in the coupling tool. The pipe end sections are retained by compression of the liner in abutting relationship with a lip formed on the interior surface of the outer sleeve. The lugs are positioned equidistant from the axial ends of the outer sleeve for insertion of the pipe end sections easily within either axial end of the sleeve.
