    Abstract: A planetary gear retrieval system for pulling a sled at a constant velocity along an interior of a pipe, and a sled for applying a coating material to the interior of the large-diameter pipe. The planetary gear retrieval system is connected to the sled via a chain, and has a network of gears controlled by a first variable speed microcontroller. A spinner on a linear oscillating plate provided on the sled is controlled by a second variable speed microcontroller. The first and second microcontrollers are programmable to be synchronized with one another so as to pull the sled at a desired constant rate and achieve a desired number of passes of the spinner along a given length of pipe while the sled is pulled at the desired rate.

    Abstract: The present invention relates to coating of tubes, and more particularly to a system and method for coating and/or renovating deteriorated or pitted tubes to extend tube life and enhance performance. Using this system and method a thin coating is applied to the interior of a tube such that the coating is uniform in thickness and covers all regions of the tube. The coating material may be selected to minimize changes in heat transfer or may be selected to provide for the change in working fluid within the tube such that the working fluid does not negatively interact with the tube material.

    Abstract: The inventive method for protecting from corrosion and scale deposit and restoring tubes of heat-exchanging equipment consists in applying a polymeric coating on the internal surface of tubes by gradually and rotationally moving an excessive volume of polymeric material therealong and in hardening said material. A polymeric compound having an at-rest viscosity ranging from 1000 to 1200 poises and a thixotropic viscosity reduction during the displacement thereof is used as a polymeric material. The inventive device for carrying out said method comprises a loading chamber (2), a connecting washer (12), a unit for progressively displacing the polymeric material provided with spaced rigid washers (4,5,6) fixed to a metallic rod (7), an elastic screw (8) having a conical shape whereby the conicity thereof ranges from 5 to 10° on the side which is opposite in relation to the connecting washer. Said elastic screw is arranged in such a way that it is enable to perform the gradual rotation, the rotation displacement being performed at a linear speed of 0.4-1.0 m/sec and the gradual displacement being performed at a speed of 1-0.49 m/sec.

    Abstract: There is provided a method of lining the internal surface of a pipe involving a larger diameter portion, said method comprising the steps of inserting a first pig into the pipe from an open end thereof, said first pig being a spherical body made of a resilient material having a diameter larger than the pipe inner diameter and having a number of grooves formed on the surface thereof for permitting air escape, injecting behind the first pig a necessary amount of resin into the pipe, inserting behind the resin a second pig into the pipe, said second pig having a diameter smaller than the pipe inner diameter such that a resin lining layer having a desired thickness may be formed on the internal surface of the pipe, providing a positive pressure and applying the positive pressure behind the second pig in the pipe, and causing the first pig, the resin and the second pig to move through the pipe along the entire length thereof by the positive pressure, so as to form a resin lining layer on the internal surface of the pipe by means of the second pig.
