Abstract

Oppfinnelsen vedrører et korrugert plastrør (1) med en glatt innervegg (5) og en korrugert yttervegg (2). Det korrugerte røret har et antall ringformede, korrugerte profiler (2) som er anordnet etter hverandre og er symmetriske om et senterplan som strekker seg perpendikulært på rørets senterakse (3). Hver korrugerte profil har en sylindrisk veggdel (5) som er konsentrisk om rørets senterakse. Videre har hver korrugerte profil en veggdel som er i hovedsaken krum i aksialsnittet (6) og strekker seg fra den sylindriske veggdelen, på en slik måte at den sylindriske veggdelen og den krumme veggdelen vil begrense en ringformet kavitet. Den indre flaten til de sylindriske veggdeler som følger etter hverandre, danner rørets glatte innervegg, og den ytre flaten til de krummede veggdeler som følger etter hverandre, danner den korrugerte yttervegg. Profilhøyden (H) til den korrugerte profilen er 6,0-8,5% av rørets indre diameter i (ID). Delingen (P) til de korrugerte profiler (2) er 15-23% av rørets indre diameter. Bredden (W) til den korrugerte profil er 77-82% av delingen.The invention relates to a corrugated plastic pipe (1) with a smooth inner wall (5) and a corrugated outer wall (2). The corrugated tube has a plurality of annular, corrugated profiles (2) arranged one after the other and symmetrical about a center plane extending perpendicular to the center axis of the tube (3). Each corrugated profile has a cylindrical wall portion (5) which is concentric about the center axis of the pipe. Further, each corrugated profile has a wall portion which is substantially curved in the axial section (6) and extends from the cylindrical wall portion, in such a way that the cylindrical wall portion and the curved wall portion will restrict an annular cavity. The inner surface of the cylindrical wall portions which follow one another forms the smooth inner wall of the pipe, and the outer surface of the curved wall portions which follow one another forms the corrugated outer wall. The profile height (H) of the corrugated profile is 6.0-8.5% of the inner diameter of the pipe in (ID). The pitch (P) of the corrugated profiles (2) is 15-23% of the inner diameter of the pipe. The width (W) of the corrugated profile is 77-82% of the split.
