Drilling, piercing and punching technology

Danobat’s T3CH CNC drilling unit

In an era of widespread registration to ISO 9001 and other rigorous standards, a faulty drilled, pierced, or punched perforation – one that is misaligned or less than clean or in the slightest degree “off” in diameter – would mean scrapping an otherwise perfect tube, and not just one. As an unintended consequence of the marvel of reproducibility in a state-of-the-art mill, a single rejection can compel the sacrifice of an entire production run of perfect tubes. Expensive scrap indeed.

It shouldn’t happen… and it doesn’t. That confident assertion rests squarely on the skill and experience that make up the stock-in-trade of companies like those whose products and services are reviewed in this section of Tube & Pipe Technology.
