Key Features & Benefits
| Feature | Petrochemical-Specific Benefit |
|---|---|
| High-Frequency Induction Heating | Precise, localized heating (800–1100°C) eliminates overheating risks in heat-affected zones (HAZ), critical for maintaining material integrity in high-pressure piping. |
| Full CNC Control System | Siemens PLC + touchscreen control ensures ±0.1° bend angle accuracy and consistent wall thickness reduction (≤12%) across carbon steel, stainless steel, duplex, and Inconel alloys. |
| Large Diameter & Thick-Wall Capability | Processes pipes up to DN1600 (63") OD and 120mm wall thickness, supporting full-size API 5L grade pipes for high-pressure process lines. |
| Advanced Ovality & Radius Control | Real-time temperature monitoring and servo-driven feed systems maintain ovality ≤1.5% for 3D/5D/7D bends, meeting ASME B31.3 specifications for leak-tight joints. |
| Water-Cooled Inductor & Cooling System | Dual-circuit cooling prevents material grain growth and scaling, ensuring mechanical properties remain intact for harsh refinery environments. |
| Heavy-Duty Hydraulic Push System | 100-ton+ push force for smooth, uniform pipe feeding, minimizing material stress and ensuring bend consistency in long production runs. |
