Benefits of technology
The invention provides a better way to remove material from pipes during pipe renovation, making it faster and more efficient than previous methods.
Problems solved by technology
However, it is possible that the actual lining step fails or that maintaining the excess pressure does not succeed because of a power failure or a human error, for example.
Disassembling of structures and replacing a pipe line with a new one is not only extremely expensive but also slow.
However, an extremely good resistance to wear is required of pipe renovation materials, such as epoxy resin, so their removal by sanding plates or grinding chains is very slow.
Moreover, a lot of sanding material is consumed and plenty of dust is formed.
Further still, a sanding device is difficult to carry forward in a complex pipe line.
During a working day, typically only a few meters of epoxy resin impregnated lining is managed to be ground, which means that a long pipe line takes several days to open.

Embodiment Construction
[0022]In the following the invention is described in more detail with reference to preferred embodiments presented by way of example and to the attached figures, wherein:
[0023]FIG. 1 shows a grinding device according to an embodiment of the invention;
[0024]FIG. 2 shows a grinding device according to an embodiment of the invention; and
[0025]FIG. 3 shows a grinding device according to an embodiment of the invention in a pipe to be milled.
[0026]FIG. 1 shows a grinding device according to an embodiment of the invention for removing pipe renovation material from a pipe. After failed pipe renovations, particularly after failed pipe lining operations, it is necessary have the pipe renovation material removed from the pipe. In connection with lining operations this means removing the lining and the epoxy resin used for impregnating it from the pipe to be renovated. A lining impregnated with epoxy resin is typically several millimetres thick and usually installed at one go along the entire p...

Abstract
The grinding device is for removing pipe renovation material from a pipe. The grinding device has at least one cutter, a body and fastening means for fastening the grinding device to a rotation shaft. The body and the at least one cutter are accomplished of a single piece for grinding pipe renovation material both in the forward direction of the grinding device and in a direction transverse to the forward direction. In addition, a system for removing pipe renovation material from the pipe and use of the grinding device for removing pipe renovation material from the pipe are disclosed.
Description
FIELD OF THE INVENTION[0001]The invention relates to a method, system and device for removing pipe renovation material from a pipe.PRIOR ART[0002]Pipes, such as water and sewage pipes, approaching the end of their service life may be renovated e.g. by lining or coating the inside of an old pipe or by mounting a new pipe into an old pipe. An epoxy resin-impregnated polyester liner, for example, that is slipped into a pipe to be renovated can be used in lining. After being slipped in, excess pressure is maintained inside the liner until the epoxy resin cures to its shape conforming to the walls of the old pipe. Modern technology allows even highly complex pipes to be lined. However, it is possible that the actual lining step fails or that maintaining the excess pressure does not succeed because of a power failure or a human error, for example. As a result, the lining is often not against the sides of the old pipes but causes a blockage or a narrowing in the pipe and the epoxy resin cu...
