Tested to 1,000,000+ cycles, designed to outlast, built for industrial reliability,
delivering continuous performance in high-frequency applications-where others fail, it endures.
Strict implementation of Quality Control to ensure excellent product quality.
Advanced Welding Techniques
In the manufacture of standard economic pressure gauges, stainless steel liquid-filled pressure gauges, vacuum gauges, differential pressure gauges, mining pressure gauges, and spiral tube fire protection pressure gauges, we employ rigorous Quality Control protocols involving High-frequent welding machine for fast and reliable welds, Silver alloy(Sn) welding for corrosion resistance, Temperature-controlled welding machine for consistent heat application, Tig(arc) welding for precision joins, Laser welding machine for high-accuracy seams, and C2H2 welding machine for versatility.
Additionally, our Economy type testing ensures cost-effective quality assessment, Static testing verifies structural integrity, Overpressure testing simulates extreme conditions, Calibrating testing guarantees accuracy, Oil injection checks for leaks, and Inspection testing ensures compliance with all standards.
Oxygen Cleaning
For standard economic, stainless steel liquid-filled, vacuum, differential, mining, and spiral tube fire protection pressure gauges, our Oxygen Cleaning process involves Ultra-sonic cleaners, Class 100 Cleaning rooms, Black light inspections, and sealed Cleaning bags to guarantee contamination-free surfaces.
