Flexible pipe connections

When the engine or generating set is resiliently installed, all connections must be flexible and
no grating nor ladders may be fixed to the engine or generating set. When installing the flexible
pipe connections, unnecessary bending or stretching should be avoided. The external pipe
must be precisely aligned to the fitting or flange on the engine. It is very important that the
pipe clamps for the pipe outside the flexible connection must be very rigid and welded to the
steel structure of the foundation to prevent vibrations, which could damage the flexible
connection.
