Pressure Control Technology:
Precisely controls pressure through proportional valves or servo systems to ensure detection accuracy.
Data Acquisition System:
Real-time collection of pressure, leakage, and other data, generating inspection reports.
Online Inspection Technology:
Monitors the inspection process in real-time through sensors to ensure result accuracy.
Modular Design:
Supports multi-station testing to improve inspection efficiency.
Pipeline & Tube Integrity Testing
Used to inspect steel tubes and pipelines for air leakage during and after production, ensuring structural integrity and preventing pressure loss.
Quality Control in Tube Manufacturing
Uses precise leakage detection to identify micro-leaks or weak welds, ensuring high-quality, leak-free steel tubes before shipment.
Pneumatic System Inspection
Applied to pneumatic systems and air-pressurized equipment to quickly detect leaks that may reduce efficiency or cause malfunctions.
Safety Assurance in Industrial Processes
Detects leakage points at an early stage to prevent safety risks, pressure drops, and costly production downtime.
Energy & Cost Efficiency Monitoring
Helps reduce compressed air waste and energy loss by locating leaks that would otherwise increase operating costs.
