Definitions

  • the present invention relates to pipe cleaning tool cups, such as pipelines for conveying fluids. It also relates to a pipe cleaning tool comprising at least one such cup.
  • cleaning tools that move in the pipes, and which include an axis on which are mounted different modules fulfilling different functions.
  • One of these modules comprises at least one circular cup dimensioned to rub against the wall of the pipe to ensure sealing so that the fluid used can not bypass the cup. Indeed, in this case, the pressure of the fluid to advance the cleaning tool may no longer be sufficient so that the tool can be slowed or stopped in the pipe.
  • the cup has the function of scraping the wall of the pipe in order to scrape deposits on the wall.
  • An object of the present invention is therefore to overcome this disadvantage, by proposing a cup of a pipe cleaning tool, and more particularly a bidirectional tool, to maintain the seal between the pipe and the tool and work to the same pressure whatever the direction of movement of the cleaning tool in the pipe.
  • each of said circular walls comprises a central core having an orifice for the passage of an axis of the tool, a circular intermediate zone surrounding the central core and a circular outer edge surrounding said intermediate zone and connected to the strip.
  • circular peripheral said intermediate zone being arranged to define a throat constituting a more deformable area than the central core and the outer rim.
  • the intermediate zone can be deformed so that the cup occupies the entire section of the pipe so as to ensure sealing.
  • the present invention also relates to a pipe cleaning tool comprising an axis, comprising at least one cup as defined above mounted on said axis.
  • Said cup 10 has a volume defined by two circular walls 1 and 2, substantially parallel and by a peripheral circular band 3 connecting said circular walls 1 and 2.
  • the cup 10 is intended to be mounted on an axis 4 of a module 5 of a pipe cleaning tool by means of fixing means provided for this purpose. These fixing means are known to those skilled in the art and will not be described in more detail. Module 5 is connected to other modules to form a complete cleaning tool.
  • the two walls 1 and 2 are arranged so that the orifices 6a are aligned for the passage of the axis 4 of the tool.
  • the circular walls 1 and 2 are preferably symmetrical with respect to a transverse plane of the cup 10. It is obvious that the walls 1 and 2 may not be symmetrical, the presence of the groove being however respected. But symmetry is better to reduce manufacturing costs.
  • the volume defined by the circular walls 1, 2 and the peripheral circular band 3 is full, with the exception of the orifice for the passage of the axis 4 of the cleaning tool.
  • the central core 6 has a height less than that of the outer edge 12.
  • the central core 6 has a height greater than that of the outer rim 12. This makes it possible to use the central core 6 as a spacer.
  • the cup according to the invention has a diameter greater than that of the pipe, preferably greater than 2% to 8%, and more preferably greater than 3 to 5% than that of the pipe.
  • the cup is made of a polymeric material, such as polyurethane.
  • the circular band 3 is preferably perpendicular to the circular walls 1 and 2.
  • the present invention also relates to a pipe cleaning tool comprising at least one cup as described above.
  • the number of cups is adapted according to the pipe to be treated.
  • the cup according to the invention is particularly effective for bidirectional pipe cleaning tools.
  • the cup When using the cleaning tool in one direction, the cup, larger than the pipe, tilts at an angle due to the pressure of the fluid exerted on the circular wall 1, while remaining in contact the wall of the pipe to maintain the seal.
  • the cup When the tool is returned in the other direction, the cup retains substantially the same inclination.
  • the pressure of the fluid which is then exerted on the circular wall 2 causes a deformation at the intermediate zone 8 so that the cup is deformed to continue to occupy the entire section of the pipe.
  • the seal is preserved and the work of the tool can be done at the same pressure as in the original direction.
  • the cup according to the invention can be used on all pipe cleaning tools suitable for cleaning pipelines, but also loading lines, risers, etc.
  • the tool can also be used as product separation pistons in a pipeline.
