High-Quality Stainless Steel Vacuum Bellows from China Suppliers | Reliable Factory for Vacuum Equipment
Product Functions
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.
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.
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.
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℃).
