Pipe repair clamp

A clamp for repairing a damaged pipe member, comprising:

• a pair of shell members having opposing longitudinally flanged faces matingly engageable to form a shell assembly around the damaged pipe member;
• segmented inserts received in a complementary annular channel formed in an inside face of the shell members at opposite ends thereof to form ring assemblies supporting longitudinally spaced-apart inner and outer annular seals between each ring assembly and the damaged pipe member;
• a shell-sealing annular channel formed between each ring assembly and the shell members;
• a longitudinal channel formed at the longitudinal faces in fluid communication with the shell-sealing channels at each end thereof;
• a pipe-sealing annular channel formed between each ring assembly and the damaged pipe member between the inner and outer seals;
• and
• means for drawing the flanges of the shell members together to form the shell assembly.

A clamp for repairing a damaged pipe member, comprising:

• at least two pairs of shell members having opposing longitudinally flanged faces matingly engageable to form a plurality of longitudinally spaced shell assemblies including a pair of end shell assemblies around the damaged pipe member;
• segmented joining inserts received in respective complementary annular channels formed in inside faces of adjacent shell members at opposing ends thereof to form longitudinally joined ring assemblies joining the adjacent pairs of shell members together;
• segmented sealing inserts received in complementary annular channels formed in inside faces of the end shell assemblies to form a pair of end ring assemblies supporting at least one annular seal between each end ring assembly and the damaged pipe member;
• a shell-sealing annular channel formed between each segmented insert and its respective annular channel formed in the shell assemblies;
• a longitudinal channel formed at the longitudinally flanged faces in fluid communication with the shell-sealing channels at either end of each respective shell assembly;
• and
• means for drawing the flanges of the shell members together to form the shell assemblies.
