Product Description
The GY168NC-3 large-diameter pipe rolling machine processes carbon steel pipe up to 168 mm OD x 6 mm wall. Three driven rollers carry the workpiece through 400 mm molds on 150 mm shafts. The supplied specification lists 180 mm/s bending speed, 22 kW hydraulic motor power, R >= 10D minimum radius, and a 6,200 kg machine weight.
The asymmetric side-roller arrangement reduces straight ends, while custom groove tooling extends the machine to suitable metal profiles.
Zhuoran reviews every large-pipe project against the drawing, material, radius, and handling plan.
GY168NC Large-Diameter Pipe Rolling Machine Model
GY168NC-3 Large Pipe Roller
Three-roller machine with 168 x 6 mm carbon steel capacity, 400 mm molds, 150 mm shafts, and 6,200 kg weight.
Custom-Tooling GY168NC-3
Pairs the machine with grooves designed for your pipe or profile section, material, rolling axis, radius, and finish requirement.
Features of GY168NC Large-Diameter Pipe Rolling Machine
168 mm Pipe Capacity
The verified specification covers 168 x 6 mm carbon steel pipe.
150 mm Shafts
Large shafts support the documented three-roller tooling arrangement for 168 mm carbon steel pipe.
22 kW Hydraulics
The listed hydraulic motor powers the pressure system for large workpieces.
6,200 kg Structure
The heavy machine body supports large-diameter rolling and production handling.
Form Large Pipe with Three Rollers
The GY168NC large-diameter pipe rolling machine uses three driven rollers to form broad curves through repeated passes. Its verified carbon steel reference capacity reaches 168 x 6 mm.
The machine does not remove the need for a part review. Send material grade, tube condition, radius, finished geometry, and acceptable ovality so Zhuoran can confirm forming margin and roller-groove design.
Build Handling into the Project
Large tube demands a handling plan before machine delivery. The GY168NC-3 weighs 6,200 kg, and the workpiece can sweep far beyond its 2,200 x 2,000 mm base while forming.
Provide stock length, finished ring diameter, lifting equipment, operator position, and available floor area. Zhuoran can use the layout to review feed direction, supports, access, and installation requirements.
Specify the Finished Section
The supplied description allows circles, arcs, spirals, and selected profiles with changed mold grooves. At this size, nominal OD alone cannot define the tooling.
The drawing should show wall thickness, weld seam, cross-section, rolling plane, target radius, straight tangents, and protected surfaces.Zhuoran can then match the 400 mm molds and contact geometry to the required GY168NC-3 part.
Applications
Large Pipe Rings
Use the GY168NC-3 for large rings made from carbon steel pipe within the verified 168 x 6 mm capacity. Your drawing must define finished diameter, joint method, straight-end allowance, and trimming plan. Zhuoran can review stock length and pass sequence before recommending tooling, supports, and a test procedure for the large-diameter pipe rolling machine.
Heavy Structural Arcs
The GY168NC-3 forms long, gradual arcs where a short-radius bender does not match the geometry. Three driven rollers feed the tube while the pressing position sets curvature. Include centerline radius, arc length, chord, tangents, tube grade, and rolling plane in the RFQ. These dimensions allow Zhuoran to review machine capacity and shop-floor clearance around the finished arc.
Large Spiral Fabrications
The source document includes spiral forming, but a spiral requires a complete geometric definition. Provide outside diameter, pitch, turn count, feed direction, straight leads, and final end orientation. Combine these values with tube size and material. Zhuoran can then assess groove design, workpiece support, available clearance, and whether the GY168NC large-diameter pipe rolling machine fits the project.

What is the GY168NC-3 capacity?
Maximum reference capacity: Ø168 × 6 mm carbon steel tube. Other materials require confirmation.
What is the minimum bending radius?
Reference minimum: R ≥ 10D. For a 168 mm tube, the radius starts around 1680 mm.
What power does it use?
The machine uses a 15 kW drive motor and 22 kW hydraulic motor. Final electrical details depend on the order configuration.
