PROCESS FOR RENOVATING PIPES |
摘要 |
A process for renovating pipes in which internal deposits in the pipe are removed by flowing abrasive agents and the pipe is coated internally with a viscous, curing material is performed to obtain a conveyance quality comparable to that of new pipes using simple technical means and the prevention of blockages by removed internal deposits during treatment in such a way that the abrasive agent is conveyed to and fro by means of an alternating pressure drop in the pipe and finally out of the pipe by means of a pressure drop between the two ends of the pipe. |
