Abstract
A novel locking pipe joint for use in fluid-carrying pipe systems is described. The locking pipe joint of the present invention provides a system of joints that will withstand the stresses and forces imposed on a pipe system carrying fluids. The joint is constructed on a push-fit principle. Sealing rings are used to make the joint leak-proof. Splines are provided to sustain the longitudinal forces imposed on the joint, and longitudinal ribs are provided on the outer surface of the joined pipes to withstand the torsional loads. The joint is simple in its construction, easy to assemble in field and cost effective.
