A method for placing a tube (11) made of plastic material within a conduit (12) in operation, comprising the stages of inundating the conduit with a liquid, then insert the tube with its initial end placed in the inundated portion, so that it slides along the conduit, while the hydrostatic impulse reduces the sliding effort. Equipment for placement of a tube (11) made of plastic material within a conduit (12) in operation, comprising a pair of collectors (15, 115), each one counting on a connection (16, 116) for the fixation of sealing to a respective end of a portion of conduit (12). Each collector comprises a fragment of tube of entry/exit (17, 117) disposed inclined with an obtuse angle in relation to the axle of the respective end of the conduit, in order to stimulate and allow the passage of the tube in the conduit, and the nozzle (18, 118) of the fragment of the tube being at high above the conduit. The equipment further comprises means (19) to inundate with a liquid the portion of the conduit closed by two collectors, in order to allow the sliding of the tube along the conduit, while the hydrostatic impulse of the liquid reduces the sliding effort in the tube.
