China Stainless Steel Vacuum Bellows Factory - High-Performance Connectors from Trusted Suppliers
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 & 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 & Temp 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℃).
Application Range
Semiconductor & Electronics
Used in vacuum pipeline connections for equipment in wafer manufacturing, etching, coating (PVD/CVD), etc., ensuring high cleanliness and pollution-free transmission.
Vacuum Pump Systems
Connected to roots pumps, rotary vane pumps, molecular pumps, etc., to compensate for vibrations and thermal displacements and improve sealing performance.
