ABSTRACT:
Apparatus and method for using a beaded liquid to reduce the coefficient of friction between the inner surface of an elongated support, such as a tubular conduit or pipe, and the outer surface of an inner member, such as a pipe or cable, disposed in and moveable along the support when the latter has horizontal and/or inclined portions. The support contains a flowable liquid which may or may not be provided with beads therein, and the inner member contacts the liquid as the inner member moves along the support. Beads are dispensed into the liquid in the support either in a dry condition or in a mixture with another liquid as the inner member moves along the support.
