Abstract
A pipe coupling for joining adjacent ends of first and second pipe sections. The coupling includes a generally cylindrical sleeve having first and second sides. The sleeve is formed as a sheet which is rolled to form the sleeve, wherein the first side of the sleeve defines a substantially continuous annular corrugation to cooperatively engage an end of a first pipe section. The connection of the pipe coupling to the first pipe section end occurs at a factory. The second side of the sleeve is in the form of a bell and defines a non-corrugated surface which is adapted to slidably receive an end of the second pipe section in the field, to thereby interconnect the adjacent ends of pipe. Gaskets may be provided to further reduce infiltration or exfiltration at the coupling.
