Built around actual post-welding inspection needs in metal hose manufacturing.
Ensure accurate and repeatable leak detection after welding. Replace manual water immersion testing with a fully controlled automated process.
The Metal Hose Leak Testing Machine is designed for post-welding airtightness inspection of corrugated and braided metal hoses.
By automating clamping, pressurization, immersion, and detection, the system delivers consistent and reliable results while significantly improving testing efficiency and operator safety.
It is widely used in metal hose production lines as a critical quality control step before delivery.
Completes the full cycle from clamping and pressurizing to immersion and lifting.
Testing accuracy is independent of operator experience and manual judgment.
Bubble visualization works together with system monitoring for easier inspection.
Single-station or multi-station solutions can be matched to production needs.
Used after welding to verify airtightness before final delivery.
Ensures reliable sealing performance on completed hose assemblies.
Suitable for post-weld inspection of braided structures and finished products.
Supports leak testing for products with different end connections and joint types.
Before automation, testing was often done by manually sealing both ends and immersing the hose in water. This machine simplifies the process and improves reliability through controlled hydraulic and pneumatic clamping.
The system applies compressed air pressure to the hose and submerges it in water. Leakage is detected through bubble formation and monitored through the control system. Station number, fixtures, and testing parameters can be configured according to production needs.
Hydraulic and pneumatic fixtures hold the hose securely for stable testing.
Compressed air is introduced according to the selected pressure setting.
The hose enters the water for bubble-based leak visualization.
The system completes detection, confirms results, and lifts the tested hose.
