Definitions

  • This invention is concerned with a calibration hose assembly suitable for use in conforming a pipeline to the interior surface of the pipeline, a closure device suitable for use in closing an end portion of a hose and a method of conforming a tubular pipeline to the interior surface of the pipeline, especially in applying a renovated pipeliner to the interior surface of a pipeline.
  • One known method of conforming a tubular pipeliner to the interior surface of a pipeline has involved the use of a scaffolding tower or other means of supporting a feed pipe extending from an entry to the pipeline upwardly for distance of about 14 feet to an inlet to the feed pipe.
  • a calibration hose is turned partially inside out by passing a first end of the hose through the interior of the hose so that a pocket is formed at a leading portion of the hose. The second end of the hose which is not
  • a length of calibration hose which is twice the total distance between the inlet to the feed pipe and the end of the tubular pipeliner which is being installed within the pipeline is required in order that the pocket can become sufficiently large to reach the end of the renovation pipeliner whilst still maintaining the head of water to the inlet of the feed pipe.
  • This hydraulic pressure urges the tubular pipeliner into engagement with the interior surface of the pipe line until the resin impregnated into the pipeliner has cured, following which the water is released from the pocket and the calibration hose withdrawn.
  • Introducing hot water into the pocket of a calibration hose as described above can cause complications for example, if the water is too hot the calibration hose itself may be adversely effected and softened so that it no longer properly fulfils its function or may bust. Furthermore, it may be difficult to cause sufficiently hot water to reach the far end of the hose pocket and thus to activate the resin at the most remote region of the pipeliner, so that it is possible that the calibration hose may be withdrawn before the resin has been promptly cured thereby leading to a risk that the pipeliner may collapse away from the pipeline to be renovated. Furthermore, the method outlined above utilises a considerable length of calibration hose and it would be desirable to reduce the amount of calibration hose needed for renovating a length of pipeline, compared with the amount needed using the method outlined above.
  • Another object of the invention is to provide an improved calibration hose assembly.

  • the release of the trapped air from the air pocket 98 improves the controllability of the insertion of me calibration hose and, indeed, may be essential (if the trapped air is substantial) to counteract die buoyancy of die air which may otherwise prevent the calibration hose being fully drawn into the pipe by the hydraulic pressure.
