Rubber-cord branch pipe with built-in flanges serves to provide compensation of displacements of pipelines being connected and to decrease the level of vibration and noise of pipelines, and pump stations.
The branch pipe is supplied with built-in, reliably fixed flanges. Strength of connection of flanges with the branch pipe exceeds strength of the branch pipe itself (at safety factor tests the branch pipe is destroyed in its cylindrical part while the coupling of flanges to the branch pipe remains intact).

Long term operation of branch pipes on booster pump plants has shown their reliability, convenience at work, durability. Branch pipes have fivefold safety factor as to the failure pressure. If the service regulations are observed, the branch pipes’ operation life of 10 years is guaranteed. Two versions of branch pipes are produced, designed for operation in cold and in hot water.
