Are you experiencing these issues with bellows applications?
▢Compensator early failureWhy is there a medium leakage due to fatigue cracks in the bellows?
▢ Vibration working condition does not meet the lifespan requirements.Displacement compensation capability rapidly degrades?
▢ Insufficient corrosion resistance of materialsAre you experiencing stress corrosion cracking in specialized media?
▢ Unreliable sealing performanceLeakage under temperature cycling conditions?
▢ New product development verification is challengingLacking a professional performance testing platform?
Professional testing capabilities cover all scenario requirements
1. Mechanics and Fatigue Performance Testing
Fatigue Life Test: Simulates actual operating conditions with pressure and displacement cycles; capable of applying axial/lateral/rotational displacement loads simultaneously; accelerated life verification based on EJMA, ASME standards.
Stiffness Characteristic Tests: Axial Stiffness, Lateral Stiffness, Bending Stiffness Measurement, Plotting Force-Displacement Characteristic Curves
Stability Tests: Column Stability, Plane Stability Evaluation, Critical Unstability Pressure Determination
2. Sealing and Pressure Resistance Performance Testing
Pressure Burst Test: Determines pressure-bearing capacity and failure mode
Airtightness Test: Helium mass spectrometry leak detection, sensitivity up to 1×10⁻⁹ Pa·m³/s
High-Temperature Sealing Test: Sealing performance under temperature cycling from -196℃ to 800℃
3. Material Analysis and Corrosion Testing
Material Composition Verification: Direct Reading Spectrometer Analysis of Major/Trace Elements
Metallographic analysis: Observe grain size, inclusions, heat treatment quality
Corrosion Performance Testing: Salt Spray Corrosion, Intergranular Corrosion, Stress Corrosion Cracking Assessment, Simulated Operating Condition Medium Corrosion Test
4. Non-destructive Testing and Dimensional Measurement
Weld Quality Inspection: Radiographic Testing, Penetrant Testing, Ultrasonic Testing
Geometric Dimension Measurement: 3-coordinate measurement of wave height, wavelength, and straightness
Thick Wall Measurement: Ultrasonic Thickness Gauge mapping for thinning areas
