Abstract
A pipe coupling for coupling adjacent ends of a pair of pipes includes a sleeve, a split-ring gland positioned around one of the ends of the sleeve, and at least one annular gasket positioned within the split-ring gland and configured to be compressed by the split-ring gland for sealing one pipe end to the sleeve. The split-ring gland includes two partially circular gland members with spaced ends defining a gap. The pipe coupling includes an armor positioned to span the gap between the spaced ends to provide a generally closed annular periphery about the gasket. The armor includes a corrugated portion having a plurality of corrugations engaging the split-ring gland and the gasket during compression of the gasket. The armor is cold formed to improve structural strength and durability.
