Pipe coupling with pipe connection rings

A pipe connection ring comprising:

• a plurality of segments;
• and
• a plurality of deformable links, each of the plurality of links connecting adjacent segments of the plurality of segments, the segments and links alternating about a circumference of the pipe connection ring, the plurality of links and the plurality of segments defining an undulating or wave-like shape, each of the plurality of links configured to allow movement of the adjacent segments upon deformation of the link connecting the adjacent segments;
• wherein the pipe connection ring defines a first axial end surface, a second axial end surface distal from the first axial end surface, an inner surface, and an outer surface distal from the inner surface.

A pipe connection ring comprising:

• a plurality of segments, each of the plurality of segments defining in cross-section a beam comprising a plurality of legs;
• and
• a plurality of deformable links, each of the plurality of links connecting adjacent segments of the plurality of segments, the segments and links alternating about a circumference of the pipe connection ring, each of the plurality of links configured to allow movement of the adjacent segments upon deformation of the link connecting the adjacent segments;
• wherein the pipe connection ring defines a first axial end surface, a second axial end surface distal from the first axial end surface, an inner surface, and an outer surface distal from the inner surface.
