Method of modifying corrugated or ribbed pipe to have a smooth outer wall |
| abstract |
Annularly or helically ribbed or corrugated semi-rigid thermoplastic pipe (58) is modified to have a smooth outer wall. The ribbed or corrugated pipe is passed through a heated sleeve (70) to squash and smooth the outer profile of corrugated pipe or bend over ribs of ribbed pipe and mold a smooth outer skin of the pipe. Apparatus for forming the modified pipe includes a travelling mold tunnel (12) for the production of ribbed or corrugated pipe and a smoothing sleeve downstream thereof. The smoothing sleeve has a heater to heat it sufficiently to mold the smoother outer skin. |
