Spiral Pipe Bending Machine Manufacturer in Ahmedabad
Dhanshree Engineering manufactures high-precision spiral pipe bending machines in Ahmedabad, engineered for repeatable bending of round tubes and pipes with controlled radii and minimal deformation. Our machines combine rigid frames, calibrated drive rolls, and digital controls to deliver smooth coils and large-radius bends for fabrication, HVAC ducts, handrails, process pipelines, and infrastructure projects.
Working Principle and Process Flow
Spiral pipe bending is achieved by feeding the tube through a set of powered rolls that apply progressive force to form a constant radius or helical coil. Servo or hydraulic drives manage speed and torque, while guide supports maintain alignment and reduce ovality. Integrated encoders monitor feed length and angle so operators can reproduce bends with high accuracy and low scrap.
Types of Spiral/Coil Pipe Bending Machines
- Three-roll pyramid benders for large radius spiral bends and rings.
- Variable-pitch spiral benders for ducts, chimneys, and helical forms.
- Profile/section benders for tubes, flats, angles, and channels.
- CNC-controlled benders with programmable radii and multi-step jobs.
- Heavy-duty hydraulic benders for thick-wall pipes and stainless grades.
Key Features and Specifications
- Hardened drive rolls with quick-change tooling for multiple diameters.
- Digital readout for radius, feed length, and roll position repeatability.
- Servo/hydraulic drives delivering consistent torque under load.
- Anti-wrinkle support and adjustable side guides to control ovality.
- Safety interlocks, e-stops, and guarded zones for protected operation.
Applications of Spiral Pipe Bending
- Handrails, architectural spirals, and circular stair structures.
- HVAC and ventilation ducts, chimneys, and flue systems.
- Oil, gas, and process lines needing large-radius bends with low stress.
- Automotive and fabrication shops producing rings, hoops, and coils.
- Infrastructure, railings, sign frames, and street-furniture projects.
