Designed to isolate the work area from the rest of the pipeline with a diameter of up to 1.6 m with a liquid or gaseous medium under pressure. They plug the pipeline in a few minutes, ensuring the environmental friendliness of the work site. Each pneumatic plug is designed for use in several standard sizes of pipes - from a pipe diameter slightly exceeding the original plug diameter to a pipe diameter equal to one and a half or two of the original plug diameters. With a pipe diameter close to the original diameter of the plug, the working air pressure in the plug and the liquid back-up pressure are maximum, and, depending on the size of the plug, are within the following limits: air pressure 4-18 kg / cm 2 , back pressure 3-12 kg / cm 2 . With a pipe diameter equal to the maximum permissible diameter of the plug, the working air pressure in the plug and the pressure of the liquid back-up are minimal, and, depending on the size of the plug, are within the following limits: air pressure 3-4 kg / cm 2, the back pressure is 1-2 kg / cm 2 .
