Abstract: A corrugated pipe includes an annular corrugated pipe body made of resilient material circumscribing a hollow conduit and including alternating annular ribs and annular valleys extending along a longitudinal axis thereof. At least one protuberance integral with the pipe body and having a protuberance sidewall extends radially outward from a modified annular rib to an apex positioned outwardly from the modified annular rib, the protuberance sidewall extends into the valleys immediately adjacent the modified annular rib.
