DIMENSION

VIBRATION EFFORT SUPPORT

The current expanded range of variable effort supports are designed keeping in mind the space constraints imposed by modern industrial complexes generating power, Refining petroleum products and off shore rigs. The design lends itself to application of high performance paints which are being increasingly specified by clients who are conscious of degradation & corrosion due to process and environmental conditions.

APPLICATION

Pipe lines constructed of steel will expand along its axis by an amount equal to its co-eff of thermal expansion when carrying hot or cold fluids. The pipe lines when suspended from Variable effort supports will allow this thermal expansion or contraction relative to structure and at the same time support the weight of the pipe to prevent sagging.

VIBRATION EFFORT SUPPORT
