Abstract
A tubular element for a drill stem includes a substantially cylindrical body and two tool joints. Each tool joint is disposed at one end of the body and provided with a threaded portion that can be joined to a complementary element. At least one of the tool joints has a lifting surface that can cooperate with a lifting tool of the element to connect it into a drill stem. The lifting surface has a non-circular cross-section forming an activation zone for a drilling fluid.
