The working principle of bellows compensator is mainly to use its elastic deformation function, compensation pipeline due to thermal deformation, mechanical deformation and a variety of mechanical vibration and axial, angular, lateral and combined displacement, the compensation function has pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction function, play a role in reducing pipeline deformation and improve the service life of the pipeline.
Brass bellows H80 H -60℃ ~ +100℃ low elasticity, hysteresis and after effect is larger, better brazing. It can be used as measuring element in non - corrosive medium and instrument with low precision.
Tin bronze bellows QSn6.5 ~ 0.1X -60℃ ~ +100℃ good elasticity, strength and corrosion resistance, hysteresis and elastic after effect is small, good brazing, widely used as a measuring element.
