The invention relates to long-dimensional flexible tubes (coiled tubing). There are several variants of the proposed basic pairs of an umbilical coiled tubing and include means of their production with multi-stage sequential shaping process of one or multiple strips at an estimated geometry, and where isolated channels, partitions and flanges are formed during this process. If required, longitudinal butts of an additional shaped longitude strips can be welded to them to form additional hydraulic channels of the umbilical coiled tubing which can be reeled up to a drum.
