概要
HYDRAULIC SNUBBERS
2. HYDRAULIC SNUBBER2.1 GeneralHydraulic Snubber is a device developed to protect high pressure/temperature piping system in powergenerating plants and various types of industrial plants. They function to restrain undesirabledisplacement of piping system or components when they are about to oscillate due to seismic or othertypes of dynamic loading, while, to allow their free movement during the thermal displacement mode.Our hydraulic snubber is designed to provide such essential two-way functions by means of asophisticated combination of hydraulic cylinder with a valve mechanism. A built-in flexible reservoir isalso a dominant design feature. As an important step among entire development works, comprehensivedesign verifications and thorough testing were conducted to assure the highest reliability. Since theywere put into service decades ago, they have been proving perfect trouble-free performance andexcellent maintainability, and thus assuring maximum safeness for operation of various piping systemswhen they were subjected to occasional dynamic events.6
