ROV Tooling
Nut splitters are designed to safely and efffectively remove a seized nut from a flange stud bolt allowing easy stud bolt removal and flange separation.
TMT's modified ROV friendly Hydraulic Nut Splitter Tool is a single acting tool with a spring return. It is fitted with an ROV D-handle for parallel jar precise operation.
The NS series are specifically designed to suit standard ANSI B16.5 / BS1560 flanges.
Tri Blade Technology provides three (3) cutting surfaces on a single blade and interchangeable heads provide maximum nut range flexibility.
TMT can also provide a 10K Intensifier that provides a means to increase tool pressure up to 10,000psi (690bar) by multiplying the ROV hydraulic system pressure.
The Hydraulic Nut Splitters include spare chisel, spare set screw and wrench used to secure the chisel. A R-400 coupler is standard.
