Product Description
The GY120NC-7 large pipe rolling machine handles carbon steel pipe up to 120 mm OD x 6 mm wall. Seven driven rollers carry the tube through 300 mm molds, while the asymmetric side arrangement reduces the straight section near each end. The supplied specification lists a 100 mm shaft, 15 kW hydraulic motor, 100 mm/s bending speed, and R >= 10D minimum radius. Use the machine for large circles, broad arcs, spirals, or selected profiles after Zhuoran matches the groove to your material, cross-section, rolling plane, and surface requirement.
GY120NC Large Pipe Rolling Machine Model
Standard GY120NC-7 Pipe Roller
Seven-roller machine with 120 x 6 mm carbon steel capacity, 300 mm molds, and a 3,300 kg body.
Custom-Groove GY120NC-7
Uses section-specific tooling designed from your profile drawing, rolling orientation, target radius, surface need, and production quantity.
Features of GY120NC Large Pipe Rolling Machine
Seven Driven Rollers
Seven rollers maintain driven contact along the heavy tube feed path.
300 mm Molds
Large molds support the verified 120 x 6 mm carbon steel reference tube.
15 kW Hydraulics
The listed hydraulic motor supplies power for the pressing and rolling system.
Bidirectional Feeding
Your team can introduce the workpiece from either side of the machine.
Roll 120 mm Tube in Passes
The GY120NC large pipe rolling machine builds a broad curve through repeated roller passes. This method suits circles and long arcs that exceed the purpose of a short-radius rotary-draw bender.
The supplied minimum radius is R >= 10D. Share the exact material, wall thickness, radius, and finished geometry so Zhuoran can review springback, support, tooling, and the required number of passes.
Plan the Material Path First
A long 120 mm tube sweeps a large area while the radius develops. The machine body measures 2,500 x 1,850 x 1,250 mm, but your working cell needs more space than those dimensions.
Show incoming stock length, finished ring diameter, lifting method, and operator position on the layout. Review our installation, commissioning and operator training service when planning the production cell.Zhuoran can then review safe loading and clearance around the GY120NC-7.
Protect the Section with Matched Grooves
Large pipe and profiles need contact surfaces that spread the rolling load across the correct faces. The supplied description allows different metal profiles when the mold groove changes.
Provide a dimensioned cross-section, material grade, weld seam location, surface requirement, and ovality limit. Zhuoran can design the GY120NC-7 tooling around your workpiece instead of applying the round-pipe groove to every section.
Applications
Large-Diameter Tube Rings
The GY120NC-7 rolls large rings from carbon steel pipe within the verified 120 x 6 mm capacity. Include finished ring diameter, joint method, trimming allowance, and permitted straight length in your drawing. Seven driven rollers feed the tube through the machine, while the process plan accounts for the material required to close and finish the ring.
Broad Industrial Arcs
Long structural arcs need a defined radius and tangent geometry. The GY120NC large pipe rolling machine applies curvature across the tube length and allows workpiece entry from either side. Provide centerline radius, arc angle, chord length, straight tangents, and rolling plane. Zhuoran can use those values to review tooling, stock handling, and machine clearance.
Large Spiral Sections
The source material lists spiral forming among the machine's functions. A useful spiral drawing needs pitch, outside diameter, number of turns, tube size, and feed direction. Include any straight leads and end orientation. These details let Zhuoran evaluate whether the GY120NC-7, its 300 mm molds, and the proposed handling setup fit the finished component.

What tube can the GY120NC-7 roll?
Maximum reference capacity: Ø120 × 6 mm carbon steel tube. Other materials need confirmation.
What is the minimum radius?
Reference minimum: R ≥ 10D. For a 120 mm tube, the starting radius is about 1200 mm.
Does it need special foundations?
The machine weighs about 3300 kg. Check floor capacity, leveling, and installation requirements before setup.
Can it roll other profiles?
Yes. It can roll round tube, angle, flat bar, and other profiles with suitable roller grooves.
