Detailed Description

By minor vertical travel of piping and related components due to thermal expansion, spring hangers and supports are used to provide elastic load transfer. The functioning of these components is based on preset helical coil springs which exert a variable supporting load over the whole range of movement corresponding to the given spring characteristics. Sai-Hao spring hangers and supports meet the requirements of consistent performance and maintenance free operation via the following features: Sai-Hao spring hangers and supports are preset at works to the installation load and blocked in both directions of movement. Blocking is necessary to take up additional loads during pickling, flushing, or hydrostatic test. The factory settings are carried out on electronically controlled test benches: values set at the factory are stamped onto a reveted plate. the installation position is marked on the travel scale. cold and got settings are marked on the travel sclae with white and red sticker respectively. the blocking device can be blocked in any position. The blocking pieces can be reinserted in any required position. Deliveries of approximately 1,000,000 Sai-Hao spring hangers and supports worldwide demonstrate their particular reliability. surface protection through galvanized finish special pre-relaxed springs integrated tightening devices adjustable blocking system
