ABSTRACT:
A locking ring designed to work in a self restraining pipe joint. This locking ring is designed (which may include attention to a combination of shape and material properties) to twist when exposed to a concentrated load and thereby distribute this load across broader area of the pipe joint to increase the thrust restraining capabilities of the joint
