The ST Series Steel Tube Air Leakage Detector is an automated industrial system for verifying the sealing integrity of stainless steel, carbon steel, and alloy steel pipes. It performs automatic loading, pressurization, dwell time monitoring, and unloading, ensuring consistent quality control. Using the bubbling method, it detects micro-leaks by submerging pressurized tubes in water and observing air bubbles-a reliable method for critical applications. Suitable for both welded and seamless pipes, the ST series handles tube lengths from 2 to 6 meters, with adjustable dwell time (5–10 seconds) and pressure up to 0.8 MPa, making it ideal for construction, automotive, petrochemical, and fluid transport industries.
