CNC Induction Heating Pipe Bending Machine for Petrochemical | High-Precision ASME/API Compliant Bending

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.
