SPRING HANGERS
Proper spring hanger function is critical to the mechanical integrity of process units. This is especially true in power plants with their High Energy Piping (HEP) circuits. Many issues cannot be seen from the ground, and spring hangers are frequently in difficult locations that get overlooked. This is where our rope access team comes in. We safely and easily gain access to these locations, and have the training and expertise to perform whatever inspection or maintenance tasks are required. Our rope access technicians can also handle rigging and, when needed, the welding capability to handle installation or replacement work.
Spring hangers are more effective than a ceiling supported on separate joists since with the latter system there is still the possibility of structural transmission through the joist supports.
Variable Effort Spring supports
A variable effort spring support is a resilient device which absorbs/accommodates the vertical displacement of a piping system. The variable support is recommended for relatively small displacement (up to about 75mm).
Constant Effort Spring supports
A constant effort support is preferred when the use of a variable effort support may be not appropriate for the following reasons:
- The vertical movement is too great for a variable effort support (approx. > 75mm)
- Only a small change in load is acceptable (e.g. close to sensitive equipment)
- Space considerations prevent the use of variable effort supports.
