The protective polymer coatings deactivated
for repairs of the pipeline of thermal power plant, the NPP.
Anticorrosive protection by means of composition of Kouteks the PR-octopus is made directly in the water environment or a caisson the next ways:
- drawing polymeric composition using the device for underwater impregnation and putting the reinforcing material;
- gluing of in advance made fiberglass shells;
1.1. Isolation of the underwater pipeline by means of the device for impregnation and winding of the reinforcing material directly under water consists in its installation on a pipe, giving to the diver of cartridges with hermetic elastic casings in which there is a rolled reinforcing material and glue, installation of cartridges in the device and a plastic naformovka on a pipe. (see rice 1, 2, p. 6.)
1.2. The technology of isolation of pipelines by gluing of fiberglass shells consists in their production, drawing on the glue surface interfaced to a pipe, installation of a shell on a pipe and pressing by its collars or wire twist.
1.3. Production of shells is made on a template surface, i.e. on a design of similar repaired. The surface of a template becomes covered by an abhesive layer (emulsion ftorplast, a polyethylene film). Then the glass-fiber material which at the same time becomes impregnated with glue is reeled up on a template. After polymerization gluing fibreglass it is cut along the forming pipe - a template and exfoliates from its surface. Thickness of a shell makes 1,5 - 2 mm, length of forming - to 1 m.
1.4. Before installation the composition with the finely divided filler entered into its structure is applied on an inner surface of a shell.
