NC Semi-Automatic Tube Bender

168NC NC Semi-Automatic Tube Bender

The heaviest wall in the NC range: tube up to Φ168 × 14 mm on a 4700 mm mandrel. Bending runs at 4°/s so thick-section tube has time to form instead of collapsing. Built for boiler, shipbuilding and heavy structural work. Angle repeatability ±0.1°, 185° maximum bend.

Overview

Product Details

Overview

The 168NC tube bender is an NC hydraulic pipe bender rated Φ168 × 14 mm in mild steel and Φ135 × 10 mm in stainless, 12 tonnes, 30 kW, with a 4700 mm mandrel and an 800 mm maximum bend radius.

A Φ168 × 14 mm steel pipe weighs around 53 kg per metre, so a six-metre length is over 300 kg — this is not a bender that gets hand-loaded, and overhead lifting or support rollers are part of the installation. Offshore structures, heavy pipe spool and power plant pipework are the typical jobs, all low volume and high value.

FAQ

168NC NC Semi-Automatic Tube Bender — Common Questions

Φ168 × 14.0 mm in carbon steel, Φ135 × 10.0 mm in stainless. Machine weight is 12000 kg with a 30 kW drive and a maximum bend radius of 800 mm.

A 14 mm wall at Φ168 mm needs enormous force and very controlled metal flow. At this size the bend itself is a slow, deliberate operation; the cycle time of the job is dominated by handling and setup, not by degrees per second.

A Φ168 × 14 mm steel pipe weighs around 53 kg per metre, so a six-metre length is over 300 kg. Overhead lifting or a pipe support roller arrangement is normally required — this is not a machine that is hand-loaded.

Offshore and marine structures, heavy pipe spool, power plant pipework, and large structural curves. These are low-volume, high-value parts where an NC machine's lower cost per part number beats CNC automation.

That is the maximum the standard machine accepts. Larger radii on this pipe size are usually produced on a pipe rolling machine instead, which forms a long sweeping curve in passes rather than pulling one bend around a die.
