ABSTRACT:
A ductile iron molded pipe joint gland used to create an effective and lasting seal between interfitting pipe sections allows considerable deflection of the joint in any direction from the axis of the pipeline without loss of seal integrity. The interfitting pipe sections are mechanically joined securely by the gland and compressible seal in a follower gland embodiment and also by angled set screws in a retainer gland embodiment. The pipe joint gland utilizes a minimum of material for reduced weight and savings of energy in its manufacture and transportation without sacrifice of strength. The construction and shallow angle of the sealing gasket engaging face of the gland prevents gasket creep under high pressure.
