Pipeline brushes ideal for U- and V-welds

High performance multi-coated carbide saw blades Tru-Cut Saw, USA, manufactures the ‘Aggressor’ range of thin kerf, carbide tipped saw blades for cutting tube, pipe and solid ferrous materials in flying cut-off and re-cutting applications. Available with carbide and cermet inserts, the multi-layered coated blades

Lessmann GmbH, Germany, manufactures pipeline brushes specially developed for professional use on U- and V-welds in the pipeline industry. Features of the company’s pipeline brushes include long lifetime and quiet operation. The brushes are particularly narrow, making them suitable for cleaning all welds at tube connections.

cut at up to 1,200 SFM and offer performance gains over high-speed steel and friction saws. Test data on a 350mm x 2.8mm x 100 tooth blade running at 250rpm achieved a 3.7 second cut time, and was able to cut six square meters of 52100 bearing steel. A special C-shaped hooked chip breaker on the face of carbide or cermet inserts allows faster chip removal and more aggressive cutting speeds. The company has its own PVD coating chamber, which allows the company to tightly control coating quality and uniformity, and allows adjustments for individual customer applications.

› Available with any bore and mounting pattern, Tru-Cut Aggressor saw blades range from 200-600mm in diameter

In addition to its Aggressor line of blades, Tru-Cut offers a full range of saw blades and services. These include custom and standard carbide tipped saws up to 3m, segmental saws and friction saws, and high speed steel saws from 100-600mm (M2 premium nitrite and M35 Cobalt). The capability also includes solid carbide saws available from stock, repair and regrinding services, and PVD coated drills, taps and milling cutters. Each saw blade sent in for repair is inspected for broken teeth, cracks, excessive wear and other visible defects. The blades are straightened to industry standard tolerances (or better), and are inspected after each repair operation is completed. All critical dimensions and tooth angles are checked, and only blades that pass inspection will be shipped.
