The dragging the pipeline

 Inexpensive repair of pipelines with minimal technical difficulties - that's the main advantage of the method of "pipe in pipe without breaking."

A new plastic pipe is pulled into the old one, and forms an annular gap is filled with a solution. This technology reduces the diameter of the old pipes, but also increases the hydraulic capacity of the pipeline.

The method of "pipe in pipe without breaking" is used for damaged pipe with a diameter of 100-800 mm by pulling them in the short PE pipe and / or long intervals.

PE pipe is pulled into the old with the hitch and winches, traction force of it is strictly controlled and for reducing friction special devices are used.

After dragging PE pipe space between new and old pipe filled with a solution. The resulting reduction in the diameter of this is compensated by the hydraulic parameters of the new pipe.
