China Stainless Steel Vacuum Bellows Supplier | High-Quality Flexible Connectors from Reliable Factory
Product Functions
Vacuum Tightness
Adopting high-precision welding technology and a special sealing structure, they guarantee no leakage in high-vacuum environments ranging from 10⁻⁸ Pa·m³/s to 10⁻¹¹ Pa·m³/s, meeting the stringent requirements of industries such as semiconductors and photovoltaics.
Displacement Compensation
Through the elastic deformation of the bellows, they absorb axial, lateral, and angular displacements, avoiding stress concentration in pipelines caused by thermal expansion/contraction or equipment vibrations, and extending the service life of the equipment.
Vibration and Noise Reduction
The flexible structure can effectively reduce vibrations and noise transmitted by equipment such as vacuum pumps and turbomolecular pumps, enhancing the stability of system operation.
Corrosion and High-Temperature Resistance
Made of stainless steel or special alloys, they are suitable for corrosive gases (such as acidic gases in CVD processes) and high-temperature environments (-200℃ to +450℃).
