Abstract
A pipe coupling for connecting grooved pipe components in end-to-end relationship has a stepped retainer key. The stepped retainer key has a lead portion and a retainer portion. The lead portion is angularly offset from vertical to a greater degree than the retainer portion.
Claims21
A pipe coupling comprising:
- a pair of coupling segments configured to engage grooved pipe components to couple the pipe components together, each coupling segment comprising
- an arcuate body having first and second ends;
- first and second bolt pads extending from the first and second ends of the arcuate body, the first and second bolt pads defining fastener openings therethrough for receiving a fastening member;
- and
- a fastener engagement surface defined on the first and second bolt pads, the fastener engagement surface being inclined relative to a horizontal plane such that the head of a fastening device inserted through the openings will apply a greater clamping force on a inner portion of the fastener engagement surface that is located radially inwardly from a center line of the fastener opening than is applied to the portion of the fastener engagement surface that is located radially outwardly from the centerline.
2 more elements
A pipe coupling comprising:
- first and second mating coupling segments, each coupling segment comprising a channel, the channel comprising an annular channel surface and a pair of opposed flanges extending therefrom, wherein the flange includes a retainer lip with a lead portion and a retainer portion, the lead portion and retainer portion being angularly offset from a vertical plane, the lead portion being offset to a greater degree than the retainer portion.
A pipe assembly comprising:
- first and second grooved pipe components;
- and
- a coupling connecting the first and second grooved pipe components in an end-to-end relationship, the coupling comprising first and second arcuate coupling segments, each coupling segment comprising:
- a channel comprising an annular channel surface and first and second flanges extending therefrom;
- and
- a retainer lip defined on the flanges configured to be received in grooves on the first and second grooved pipe components, the retainer lip having a stepped inner surface, the stepped inner surface defining a lead portion at the leading edge of the retainer lip and a retainer portion extending from the annular channel surface, the lead portion extending from and angularly offset from the retainer portion, wherein a lead angle defined by the lead portion is greater than a retainer angle defined by the retainer portion.

A pipe coupling comprising:
- a pair of coupling segments, each coupling segment comprising a channel defined by an annular channel surface and a pair of opposed flanges extending therefrom;
- a seal configured for insertion into the channel, the seal comprising:
- a seal body;
- a pair of opposed flanges extending from the seal body and defining a space therebetween;
- and
- a cut shield positioned in the space between the flanges.
