Abstract (en)
[origin: EP3825511A1] Method and apparatus for the descent of pipelines in vertical or inclined wells, or their coating, even in conditions of well's or pipeline's axis not perfectly straight.Those method and apparatus are used in the construction of systems for the transport of water, gas and other fluids, in which the laying of pipelines or the lining of the above mentioned wells is achieved assembling together individual tubular units joined together to form a continuous tubing. The proposed method and apparatus are particularly advantageous in situations where the high height of the well or a small diameter make the making of a metallic coating complicated and expensive.The proposed method and apparatus allow the laying (descent) of the covering inside the well as a continuous pipeline, assembled outside the well, without the need for assemble the individual units of the pipeline and perform the checks inside the well.
