Please note!

Two annular ring seals are used to seal the annular space between the casing or cor

e

bore and the pipeline and to ensure the axial guidance of the piping. As the ring seals

are in a split version they can also be installed after the installation of the pipeline

.

After installation of the seal insert the pipe must not be axially displaced or misaligned.
