Every assembly undergoes 100% helium leak detection at 1.6MPa — zero leakage verified. Weld seams inspected. Salt spray tested. High and low temperature cycling validates fatigue life. Material verified by spectrometer. Test reports available upon request.
* All bellows are 100% tested before shipment. Test reports available upon request.
Valve sizing by your flow and pressure specs. Material compatibility analysis for your coolant type. Custom end connections (Tri-Clamp, weld, flange). Actuator selection support (manual, pneumatic, electric).
Why are metal bellows used in liquid cooling piping systems?
Metal bellows absorb thermal expansion, mechanical vibration, and connection-end displacement. They provide flexible connections that protect CDU pump interfaces and heat exchangers from stress-induced fatigue.
How does automatic welding improve bellow reliability?
Fully automatic orbital welding produces uniform seams with no missed welds or weak points. Achieves zero leakage at 1.6MPa — eliminating the micro-crack defects common in manual welding.
What does electrolytic surface treatment do for bellows?
Post-weld electrolytic treatment removes surface micro-cracks, creating a mirror-smooth inner wall. Corrosion resistance and fatigue life are tripled, retaining metallic luster after five years of continuous operation.
How does multi-directional compensation protect cooling system piping?
Metal braided construction absorbs axial compression, lateral offset, and angular deflection simultaneously. Compensates thermal expansion, vibration, and connection-end movement — protecting pump and heat exchanger interfaces.
