Pipe coupling with assembly tool

摘要

A pipe coupling includes mating hub sections engaged by outer split clamp elements that are compressed together against mating tapered surfaces of the hub sections to draw the hub sections together into tight fitting relationship. The clamp elements are driven into a compressed condition by an outer locking ring that fits over the split clamp elements to draw the hub sections together and to retain the hub sections against axial separation. The clamp elements have locking surfaces engageable by the locking ring and axial movement of the locking ring is limited by appropriate stop surfaces and retainers. A locking sleeve installation and removal tool utilizing an actuator system is described.
