Metal sleeve for pipe leakage point - consists of ring around sleeve ends, recess, with coated spirals

摘要

The metal sleeve (6) for bridging a leakage-point in a pipe (2) is placed against the inner wall of the pipe. The ends (8), of the sleeve have a ring around their periphery, which, when a set temp. is reached, forms a seal between the sleeve and the pipe. The ring is set in a recess (9) in the sleeve and has an outer dia. matching that of the sleeve. The sleeve's outer surface between the threads of the spiral part of the ring is coated with a coating (11). USE/ADVANTAGE - The metal sleeve is joined to a pipe, and without welding, forms a tight seal against leakages.
