CONSTANT SUPPORTS
Constant supports—often called constant spring supports or constant effort supports—are specialized pipe hangers designed to apply a nearly unvarying supporting force over the full range of a pipe’s vertical movement (e.g., due to thermal expansion or contraction). Unlike variable rate spring hangers (where load changes proportionally with deflection), constant supports use mechanical linkages or multiple springs arranged to mathematically counterbalance changes in spring compression, keeping the force within a very tight band (typically ±6 %) regardless of travel.
When and why to use them
- Large vertical travel: Whenever thermal expansion/contraction exceeds roughly 75–100 mm (3–4 in) and variable spring hangers would see load swings over 25 %, a constant support is recommended.
- Critical, strain-sensitive equipment: On lines feeding pumps, compressors, turbines or other equipment that cannot tolerate residual stress variations. Constant supports prevent “cold” or “hot” loading spikes that could damage sensitive flanges or instruments.
- Space or configuration constraints: In tight layouts where multiple variable hangers or travel loops aren’t feasible, a single constant support can handle large movements without needing extra piping flexibility.
Given below are different types of constant supports that PANSON Offers:
