1. Reasonable structure, good elasticity, large range of compensation pipeline and little counterforce to the brackets of pipeline.
2. Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket.
3. The displacement of stainless steel bellows can be deflected to prevent damage caused by subsidence of connected brackets and equipment base. Stainless steel bellows can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance.
4. Good resistance to mill, heat, aging and corrosiveness and long service life.
5. Little resistance and little weight. Each performance is better than the compensation device of other materials.
6. The temperature rage of media is wide:-40--300oC
