Abstract (en)
[origin: CA2966957A1] The invention concerns a tubular drill stem component (1) comprising an end element (2; 3) having an axis of revolution (XX) and provided with a threading extending about the axis of revolution (XX), the end element (2; 3) being adapted to being connected by makeup onto a corresponding end element (103; 102) of another tubular component (101) provided with a complementary threading, the end element (2; 3) comprising at least one outer abutment (18) arranged so as to come into contact with a corresponding outer abutment (128) of the other component (101) at the end of makeup, and in which said outer abutment (18) comprises at least one helical surface (38; 148) having an axis of the helix which coincides with the axis of revolution (XX).
