Abstract
Possibility of quick fixes or need to extend life of existing thin-walled structural elements, such as pressure vessels, piping and other, workers under internal pressure media, seems promising application of pressurized protecting sleeve. Such a sleeve could consist of a divided metal housing or jacketed sleeve and curable sealing elements or curable filling materials. This solution is particularly suitable for repairing corrosion-damaged pipelines. The main problem of this technology is to select an existing filling material. Materials as fillers must meet a number of specific requirements. One of the main goals was to determine the rate of decline in the relative volume changes and the rate of pressure drop. Appropriate method was chosen using the results of strain measurement.
