The aircraft cylinder hydrostatic expansion test system is dedicated equipment for mandatory inspection of aviation cylinders. It integrates high-pressure water boosting, pressure measurement and control, and volumetric-deformation acquisition for hydrostatic testing and permanent volumetric expansion measurement during periodic inspection, factory acceptance, and post-overhaul reinspection.
Aircraft Cylinder Hydrostatic Expansion Test System

· Strict compliance with international water-medium testing standards provides inherently safer high-risk testing.
· A high-precision volumetric measurement system accurately detects elastic and permanent residual deformation of cylinders under high pressure.
· A fully automatic one-touch sequence covers water filling and venting, pressurization, pressure holding, depressurization, and data acquisition, greatly reducing operator error.
· Test data are automatically recorded and stored, and compliant reports are generated. Tamper-resistant records support lifecycle traceability and certification audits.
· Hydrostatically tests onboard high-pressure cylinders to determine continued serviceability.
· Periodic in-service inspection of cylinders and pressure vessels using high-precision volumetric expansion measurement to determine continued safe service and prevent fatigue-related failure.
