Abstract

A restrained pipe coupling includes a restraining gland assembly having an annular main body with multiple gripper units movably connected to the annular main body. Each gripper unit includes a gripper housing having a bottom sliding surface, a gripper bolt fixedly secured to the gripper housing and radially movable through a gripper opening in the annular main body and fixable at different positions, and a gripper body having a top sliding surface and a bottom gripping surface. The sliding surfaces of the gripper housing and the gripper body are in slidable contact and angled between 20 and 30 degrees from the axial direction of the annular main body.
