Description

Description
Dish for a pipe-cleaning tool Technical field
The present invention relates to dishes for a tool for cleaning pipes, such as pipelines for transporting fluids. It also relates to a pipe-cleaning tool comprising at least one dish of this type.
Prior art
The pipes or pipelines referred to in the present description are used for transporting fluids, such as petrol, kerosene or gases such as hydrogen and oxygen. These pipes are for example provided between a well and a rig, or for loading fluids, for example between a rig and a boat. For safety reasons, these pipes must be monitored, surveyed and cleaned regularly.
For this purpose, cleaning tools are used which move in the pipes and which comprise a shaft on which different modules having different functions are mounted. One of these modules comprises at least one circular dish dimensioned so as to rub against the wall of the pipe to ensure sealing so that the fluid used cannot pass around the dish. In fact, in this case, the pressure of the fluid for advancing the cleaning tool would no longer be sufficient, such that the tool may be slowed, or even stopped, in the pipe. At the same time, the dish has the function of scraping the wall of the pipe so as to scrub the deposits that have accumulated on the wall. A dish of this type is described in US-A-9306576.
Moreover, in the case of bidirectional tools, it is important for there to be sealing in the region of the cleaning tool so that it is possible to work at the same pressure in the two directions of movement of the tool.
Current bidirectional cleaning tools comprise dishes having the shape of a planar disc which a priori does not have any influence on the movability of the cleaning tool. Some systems provide the use of discs which have greater dimensions than those of the pipe and have a certain level of flexibility. However, the drawback of these discs is that, when the fluid is reversed, these discs only turn the other way under great pressure. In addition, once they have, they are no longer completely sealed.
The problem addressed by the present invention is therefore that of overcoming this drawback by proposing a dish of a pipe-cleaning tool, and in particular a bidirectional tool, which allows the sealing between the pipe and the tool to be maintained and allows work to be done at the same pressure, regardless of the direction of movement of the cleaning tool in the pipe.
Disclosure of the invention
For this purpose, and according to the present invention, a dish for a pipecleaning tool having a space defined by two substantially parallel circular walls and by a peripheral circular strip connecting said circular walls is proposed.
According to the invention, each of said circular walls comprises a central core having an orifice intended for letting through a shaft of the tool, a circular intermediate area surrounding the central core and a circular outer edge surrounding said intermediate area and linked to the peripheral circular strip, said intermediate area being laid out so as to define a groove forming a more deformable area than the central core and the outer edge.
Therefore, the intermediate area may deform so that the dish occupies the entire cross section of the pipe so as to ensure sealing.
The present invention also relates to a pipe-cleaning tool comprising a shaft, comprising at least one dish, as defined above, mounted on said shaft.
Brief description of the drawings
The invention will be better understood upon reading the following description, given by way of example and with reference to the drawings, in which: - Fig. 1 to 3 are a plan view, a cross section along line AA and an isometric view of a first variant of the dish according to the invention, respectively, - Fig. 4 to 6 are a plan view, a cross section along line AA and an isometric view of a second variant of the dish according to the invention, respectively, and - Fig. 7 is an isometric view of a module of a cleaning tool comprising dishes according to the invention.
Embodiment(s) of the invention
With reference to Fig. 1 to 3, a first variant of a dish according to the invention is shown.
Said dish 10 has a space defined by two substantially parallel circular walls 1 and 2 and by a peripheral circular strip 3 connecting said circular walls 1 and 2.
As shown in Fig. 7, the dish 10 is intended to be mounted on a shaft 4 of a module 5 of a pipe-cleaning tool using the attachment means provided for this purpose. These attachment means are known to a person skilled in the art and will not be described in greater detail. The module 5 is connected to other modules to form a complete cleaning tool.
According to the invention, each of said circular walls 1, 2 of the dish 10 comprises: - a central core 6 having an orifice 6a intended for letting through the shaft 4 of the cleaning tool, - an intermediate area 8 surrounding the central core 6, and - a circular outer edge 12 surrounding said intermediate area 8 and linked to the circular strip 3.
Said intermediate area 8 is laid out so as to define a groove forming a more deformable area than the central core 6 and the outer edge 12.
The two walls 1 and 2 are arranged so that the orifices 6a are aligned for letting through the shaft 4 of the tool. In addition, the circular walls 1 and 2 are preferably symmetrical with a transverse plane of the dish 10. It is clear that the walls 1 and 2 cannot be symmetrical, since the presence of the groove is respected; however, the symmetry is preferable for reducing manufacturing costs.
Advantageously, the space defined by the circular walls 1, 2 and the circular peripheral strip 3 is full, except for the orifice intended for letting through the shaft 4 of the cleaning tool.
In this variant, the central core 6 has a lower height than that of the outer edge 12.
Fig. 4 to 6 show a second variant of the invention. The elements are provided with the same reference numerals as those in Fig. 1 to 3.
In this second variant, the central core 6 has a greater height than that of the outer edge 12. This allows the central core 6 to be used as a spacer.
Advantageously, the dish according to the invention has a diameter greater than that of the pipe, preferably greater by 2 % to 8 % and more preferably greater by 3 % to 5 % than that of the pipe.
Preferably, the dish is made of a polymeric material, such as polyurethane.
To promote the sealing and scraping, the circular strip 3 is preferably perpendicular to the circular walls 1 and 2.
In addition, still with the aim of improving the scraping, the circular strip 3 may be moulded so as to produce a rougher surface.
The present invention also relates to a pipe-cleaning tool comprising at least one dish as described above. The number of dishes is adapted depending on the pipe to be treated. If the pipe has bends, it is preferable for at least two dishes to be provided.
The dish according to the invention is particularly effective for bidirectional pipecleaning tools.
When using the cleaning tool in one direction, the dish, which is larger than the pipe, is inclined at a certain angle owing to the pressure of the fluid exerted on the circular wall 1, while remaining in contact with the wall of the pipe to maintain the sealing. When the tool is moved back in the other direction, the dish maintains substantially the same inclination. The pressure of the fluid which is thus exerted on the circular wall 2 causes a deformation in the region of the intermediate area 8 such that the dish deforms in order to continue to occupy the entire cross section of the pipe. Therefore, the sealing is maintained and the work of the tool can be carried out at the same pressure as in the initial direction.
The dish according to the invention may be used on any pipe-cleaning tool that is appropriate for cleaning pipes of the pipeline type, but also loading pipes, risers, etc. The tool may also be used as a piston for separating products in a pipe.
