Title:
TEST DEVICE FOR OIL WELL PIPE THREADED JOINT
Document Type and Number:
WIPO Patent Application WO/2011/138926
Kind Code:
A1
Abstract:
Disclosed is a test device (1) for estimating the performance of a threaded joint of an oil well pipe by using a first steel pipe (P1) and a second steel pipe (P2). The test device (1) is provided with a base (2) which vertically erects and secures the first steel pipe (P1) in such a way that the tip section thereof is made to protrude from the upper surface of the base (2), and that a portion of the remainder of the first steel pipe (P1) is positioned underground. A support member (3) which is mounted on the base (2) is disposed beside the first steel pipe. The second steel pipe (P2) is suspended above the first steel pipe (P1) by means of a suspension mechanism (4). The threaded joint is fastened or released by rotating the second steel pipe (P2) with respect to the first steel pipe (P1) by means of a first tong (5) and a second tong (6). A sway brace apparatus (7) which is held between components of the support member (3) restricts the maximum sway amount of the second steel pipe (P2) within a predetermined value.
