Spring Supports Overview
Variable Spring Supports
Hot or cold liquids or gases that are transported through pipeline can have different operating temperatures and ambient temperatures. The difference in temperatures can cause the pipeline to expand or contract. This is why Variable Spring supports were invented, and they work to:
- Support the weight of piping or equipment while allowing a degree of movement relative to the supporting structure
- Support the pipe in operating and ambient conditions, while permitting movement between the two Rilco Variable Spring Supports
- Used for ambient temperature variation, for long vertical pipe runs or where pipes run between buildings that may be subject to relative movement due to subsidence or earthquake.
- As the pipe moves upwards, the force exerted by the spring decreases
- Conversely, during downward travel, the force of spring increases
Constant Spring Supports
The engineering concept of Constant Spring supports are identical to that of Variable Spring supports. One major difference is when the movement in the pipeline causes too great variability for Variable Spring, or the load condition is too high for Variable Spring, a Constant Spring is used instead.
