The HWSFRT-DN400-S40 is a heavy-duty, high-efficiency Hot Induction Elbow Machine engineered for manufacturing large and medium-diameter pipe elbows up to 406 mm (16 inches). Combining an advanced hydraulic propulsion system, medium-frequency induction heating, and an automatic feeding system, it delivers smooth bending, uniform wall thickness, and exceptional structural stability for demanding industrial pipeline projects.
180 tons total thrust (2 cylinders); bore 220 mm; piston rod diameter 160 mm; effective stroke 4 meters
Hydraulic Working Pressure
0 – 25 MPa (test pressure: 31.5 MPa)
Working Environment
Temperature 5–38°C; relative humidity ≤82%; 380V 3-phase 4-wire (50Hz); designed for 24/7 continuous industrial operation
Core Features & Advantages
High-Performance 2-Stage Hydraulic Pump Station
Driven by a 35kW servo motor paired with a 50cc/r high-frequency oil pump (80 L/min flow rate).
Stepless variable working speed (0–500 mm/min), max forward speed of 1200 mm/min, and fast retract speed of 1800 mm/min.
Integrated block connections, precision seamless bright tubes, and 4-layer steel wire high-pressure hoses ensure zero leakage.
Rigid Machine Body & Smooth Guide Structure
Built with high-grade Q235A medium plates, channel steel, and round steel for long-term durability.
Push plate and base frame adopt an upper pulley and guide rail mechanism for ultra-smooth, stable running.
Front and cylinder baffles are equipped with independent hydraulic mandrel adjustment cylinders.
Advanced Heating & Fully Automated Operation
Medium-frequency induction heating provides fast and uniform thermal distribution.
Integrated automatic feeding system with hydraulic slide plates, hydraulic rollers, and hydraulic gates.
Centralized control cabinet integrates the medium-frequency power supply, motor controls, and real-time status displays.
