Stainless Steel Metal Bellows

Stainless steel bellows for flexible connection in liquid cooling piping systems. Absorbs thermal expansion, mechanical vibration, and connection-end displacement. Designed for data centers and high-performance cooling equipment.

Nominal pressure	PN6/PN10
Temperature range	-40 ℃ to 120 ℃
Test standard	GB/T 14525-2010

Product Description

The metal bellows compensates for thermal expansion, vibration, and connection-end displacement in liquid cooling loops, protecting pump and heat exchanger interfaces from stress fatigue. High temperature and pressure resistance suit continuous-duty cooling circuits. Strong corrosion resistance ensures long-term reliability with water and glycol-based coolants. The bellows design reduces mechanical stress across pipe connections, extending system service life.

Thermal Compensation

Absorbs pipe expansion and contraction during temperature cycling

Vibration Damping

Isolates pump vibration from connected piping and equipment

Corrosion Resistance

Durable stainless steel construction for long-term cooling fluid exposure

High Reliability

Designed for extended service life in continuous-duty applications
