Abstract

Tubo de perforación perfeccionado para canteras y minas, esencialmente caracterizado porque los cabezales macho y hembra llevan realizados, en las zonas de contacto con el tubo central, orificios ciegos según ejes perpendiculares al eje longitudinal del conjunto, orificios que quedan coincidentes con otros realizados al efecto en el tubo, de modo que se permite la inclusión en ellos, de unos pitones de anclaje, cuyo frente exterior queda remetido por debajo del contorno exterior del tubo, realizándose un cierre o soldadura que conecta el pitón al tubo y a las cabezas.
