Linkage System of Land circulation Drilling with inverse Correlation

摘要

Linkage System of land used in reverse circulation Drilling. The Drilling System is a useful Cutting operation, a drill, for example, through a Linkage that comprises a Central Passage (3) which are the products of Excavation, the effect of the Suction caused by the Air comoprimido injected by a SIDE STEP (2).The central STEP (3) is defined by a Cylindrical conduit (6) and the side STEP (2) by a few angular (7) welded pipe (6). The duct is formed with a series of segments that are each on two joints, Male and Female (9) (8), at its ends.
