Product Description

At LISEGA, standard supports form the basis of a comprehensive performance package. A complete program from more than ***0 standardized components thereby covers all operational loads, temperatures and travel ranges normally met in piping systems in industrial plant construction: ➜ **0kN nominal load for all mainly statically determined components ➜ ***0kN nominal load for rigid struts and standard shock absorbers ➜ ***0kN design load for large bore shock absorbers ➜ **0mm travel range for constant hangers ➜ **0mm travel range for spring hangers Product group 1 Constant hangers: Constant hangers are used for piping and related components where higher levels of vertical travel occur. Their job is to transfer the working load over the whole travel area while maintaining constancy, *****, without any considerable deviations. The functional precision of the constant hanger is decisive for the favorable long term behaviour of the components concerned. A distinguishing feature of LISEGA constant hangers is their unique operating concept. It puts into effect the principle of the parallelogram of forces, which provides the following fundamental advantages: ➜ absolute constancy based on a principle ➜ load-symmetrical mechanics and structural shape ➜ no leverage deflection or momentum effects ➜ directly readable load and travel scales ➜ load adjustment of *0 - **0 % of nominal load ➜ special pre-relaxed springs ➜ *0, **0 load cycles at constant accuracy ➜ approval by independent authorities A load range of 0, 1 - **0 kN, and a travel range of up to **0 mm are covered as standard. Product group 2 Spring hangers: By minor vertical travel of piping and related components due to thermal expansion, spring hangers are used to provide elastic load transfer. The requirements for these components are consistent performance and maintenance free operation. LISEGA spring hangers prove themselves especially advantageous in service via the following features: ➜ surface protection through galvanized finish ➜ no welded seams ➜ special pre-relaxed springs ➜ adjustable blocking system ➜ approval by independent authorities Product group 3 Product group 3 encompasses all those components which are dynamically stressed, *****, subject to alternating load directions. These dynamic restraints are fitted to protect piping and other plant components against unforeseen displacement resulting from shocks. Normal operational thermal expansion must not be thereby obstructed. Shocks can be caused by internal or external stimuli, such as water hammer or earthquake. Additional conceptional applications are the support of planned thermal expansion through guides and the securing of points of zero movement. With vertical riser pipes, the formation of “flexible” fixed points is a frequent requirement. For optimum coverage of the various applications, specialized products are correspondingly required. Where upto- date pipe support concepts are concerned, LISEGA’s rigid struts, energy absorbers and shock absorbers (snubbers) form indispensable elements for the control of dynamic loads.
