An in-line bell pipe is provided, formed by joining at least two corrugated sections of pipe having male (28) and female portions (20) to connect the corrugated sections. Each corrugated section has a plurality of first corrugations (22), each having a crest (25) and a valley (28) with the distance between the crest (25) and valley (25) of the first corrugations (22) being a first distance. The male portion (18) of each corrugated section has at least one second (32) and one third (42) corrugation, each second and third corrugation respectively having a distance between the crest and valley of each being a second and third distance respectively. At least one third corrugation crest (45) has a recessed area (55) which accomodates a sealing element (60) retained between the recessed area (55) and the female portion (20). The second and third distances each are less than the first distance.
L'invention concerne un tube comprenant une tulipe en ligne formé par l'assemblage d'au moins deux segments ondulés d'un tube comprenant des parties mâle (28) et femelle (20) permettant de relier les segments ondulés. Chaque segment ondulé comprend une pluralité de premières ondulations (22) comprenant chacune un sommet (25) et un creux (28), la distance séparant le sommet (25) du creux (25) des premières ondulations (22) étant une première distance. La partie mâle (18) de chaque segment ondulé comprend au moins une seconde ondulation (32) et une troisième ondulation (42), chacune ayant une distance séparant le sommet du creux qui constituent respectivement une seconde distance et une troisième distance. Au moins un troisième sommet d'ondulation (45) présente une zone creuse (55) destinée à recevoir un élément de scellement (60) retenu entre la zone creuse (55) et la partie femelle (20). Les seconde distance et troisième distance sont inférieures à la première distance.
