● The first support should be located as close as possible to the flexible connection. Next
support should be 0.3-0.5 m from the first support.
● First three supports closest to the engine or generating set should be fixed supports. Where
necessary, sliding supports can be used after these three fixed supports to allow thermal
expansion of the pipe.
● Supports should never be welded directly to the pipe. Either pipe clamps or flange supports
should be used for flexible connection.
Examples of flange support structures are shown in Figure 5-2. A typical pipe clamp for a
fixed support is shown in Figure 5-3. Pipe clamps must be made of steel; plastic clamps or
similar may not be used.
