1. Innovation in core technology
1. Forging simulation process
● Adopting the composite process of hot drawing precision welding
● Grain size reaches ASTM 7 or higher
● Mechanical properties are close to the level of forgings (tensile strength ≥ 485 MPa)
2. Improved welding structure
● Welding in a narrow-slotted pulsed gas environment
● General Post-Weld Heat Treatment (SR QT)
● 100% non-destructive TOFD testing
3. Intelligent Monitoring System
● Optional:
● Online monitoring of valve body voltage
● Sealing surface wear detection
● Wireless Data Transmission Module
