Double coupling PRO AQUA Terra

The coupling is designed to connect pipes in places where, for a number of reasons, pipes without a socket are used: in areas of pipeline rupture due to careless use of engineering machines, or due to the displacement of layers of the earth's crust, which led to the destruction of the integrity of the existing free-flow sewer pipeline.      In this place it is necessary to cut out a part of the damaged pipe and insert a piece of the repair pipe, which will be fastened with the help of a coupling.
