Constant hangers and constant supports


HYDRA® constant hangers and constant supports are mobile pipe supports with constant load-bearing behaviour and are necessary if greater vertical movements (>60 mm) have to be absorbed. All rotatable bearings are a combination of polished, stainless steel axles and PTFE composite bearings that guarantee low friction levels. Optimum corrosion protection as well as problem-free assembly and connection to the support structure guarantee maintenance-free use.

Load/travel characteristic

Konstanthänger und Konstantstützen Last Weg Charakteristik Image Text

Characteristic: Load/travel diagram with the acceptable tolerance limits in recognized guidelines (e.g. VGB-R 510 L, KTA 3205.3). The buckling-resistant design, production and special thermal treatment guarantee a linearly unchangeable force-travel-curve of the springs.

Nominal load: FN (Maximum load of the constant hanger)
Required load: FS
Set average load: Factual, average
Condition for the average setting: (|FS- Factual, average|)/FS ≤ 0.02
Nominal travel: sN
Required travel: sS
Travel reserve: sR 1"
