HNC Series Tri-Blade Heavy-Duty Flange Nut Cutters
Engineering Overview & Structural Features
The HNC Series Tri-Blade Heavy-Duty Flange Nut Cutters deliver formidable hydraulic splitting forces from 103 to 193 Metric Tons, engineered specifically for removing corroded, seized, and frozen heavy hex nuts on standard ANSI B16.5 and BS1560 piping flanges. Incorporating patented Tri-Blade geometry with three cutting edges on each indexable blade, interchangeable cutting heads, and a preset millimeter depth scale, the HNC Series ensures swift, spark-free nut splitting without damaging underlying bolt stud threads or adjacent flange faces.
ANSI B16.5 & BS1560 Flange Fit
Specially designed compact cutting head fits standard ANSI B16.5 and BS1560 pipeline flanges, enabling clean insertion between tightly spaced stud bolts without impacting adjacent hardware.
Tri-Blade Indexable Cutting Technology
Patented Tri-Blade technology provides three distinct cutting surfaces on a single indexable blade, tripling operational service life and providing maximum nut cleavage performance.
Preset Scale for Thread Protection
Features an integrated calibrated millimeter scale for controlled blade extension, stopping the cut precisely at the nut wall and completely preventing damage to critical bolt threads.
Nickel-Plated Body & Overload Valve
Nickel-plated cylinder barrel delivers exceptional corrosion resistance in harsh offshore subsea environments, outfitted with internal relief valves and heavy-duty handles for secure maneuvering.
OEM Cross-Reference & Dimensional Interchangeability
Heavy-tonnage hydraulic flange nut cutters delivering 103 to 193 Ton cutting force with patented Tri-Blade geometry for standard ANSI B16.5 and BS1560 flanges. 103 - 193 Ton / M45 - M90 (70 - 130 mm Hex).
