ISO-K Compressible Bellows Connections are high-performance expansion compensators designed specifically for vacuum and low-pressure industrial piping systems. These bellows combine the internationally standardized ISO-K flange interface with a convoluted, axially compressible bellows core. The result is a flexible connection that absorbs thermal expansion, compensates for pipe misalignment, and dampens mechanical vibration—all while maintaining vacuum integrity down to 10⁻⁸ mbar. Manufactured from stainless steel (AISI 304, 316L, or 321), ISO-K Compressible Bellows Connections feature clamp-flange ends that enable rapid tool-free assembly. They are ideal for semiconductor fabrication lines, research vacuum chambers, thin-film coating equipment, and cryogenic transfer systems.
ISO-K Flange Compatibility: Direct connection to all ISO-K flanged ports (DN 10 to DN 200) using standard centering rings and clamps.
High Axial Compression: Achieves up to 30% of free length in axial travel, absorbing thermal growth without pipe stress.
Extreme Vacuum Performance: Helium leak-tested to ≤1×10⁻⁹ mbar·L/s for UHV (ultra-high vacuum) systems.
Wide Temperature Range: Operates from -196°C (liquid nitrogen) to +450°C (continuous duty).
Lateral & Angular Capability: Accommodates ±5 mm lateral offset and ±15° angular deflection simultaneously.
Choosing ISO-K Compressible Bellows Connections over rigid spools or standard flexible hoses provides three critical advantages. First, installation speed improves dramatically—ISO-K clamps tighten in seconds without tools, reducing downtime by up to 80% compared to bolted flanges. Second, thermal stress elimination prevents flange leakage and gasket failure in systems with frequent temperature cycling (e.g., bake-out cycles in vacuum furnaces). Third, the compressible design extends component life: where a rigid pipe would transfer movement forces to vacuum chambers or turbopumps, ISO-K bellows absorb that movement, reducing mechanical fatigue failures by an estimated 70%.
Vacuum-Ready: Cleaned and packaged for high-vacuum or UHV service (no particle contamination).
Tool-Free Assembly: ISO-K clamps and centering rings reduce assembly time and eliminate thread galling.
Cycle Life: Tested to 20,000 full compression cycles without fatigue failure.
Custom Lengths: Available from 50 mm to 500 mm compressed length; extended lengths for larger travels.
Bakeable Design: Withstands 250°C bake-out for vacuum chamber degassing (flange seals replaced separately).
Cost-Effective: 50% lower installed cost than welded bellows with custom flanges.
