''Tubes à manchettes'' applications

 

The ZI double packers Ø 28, 30 and 42 mm are specially  designed for "tubes à manchettes '' grouting use ; the injection zone length ( IZ) remains constant regardless of the diameter of the “tube à manchettes”.
The bottom element of the packer is flexible making it easy to introduce into and retrieve from the “tube à manchettes”. The choice of which packer to use depends on the “tube  manchettes” inner diameter. Please refer to the selection chart shown on the left.
