AI Technical Summary
Technical Problem
Seamless steel pipes are difficult to maintain balance during lifting, which affects safety.
Method used
A lifted seamless steel pipe is designed. By setting sharp corners with axially symmetrical integrally formed at both ends of the steel pipe body, and opening an annular concave surface on the outer wall of the steel pipe body to adapt to the lifting rope, a limit structure is formed to improve connection stability.
Benefits of technology
Effectively maintain a stable connection between the lifting rope and the steel pipe body, avoid the risk of steel pipe falling, ensure that the seamless steel pipe remains balanced during the lifting process, and improve safety.

Abstract
The utility model discloses a hoisting type seamless steel tube, which relates to the technical field of seamless steel tubes and comprises a steel tube body, sharp corner parts are integrally formed at two ends of the steel tube body in an axial symmetry manner, two opposite side surfaces of the sharp corner parts are perpendicular to the tangent plane of the surface of the steel tube body, and an annular convex surface is formed on the inner wall of the steel tube body. And the distance from the annular concave surface to the annular convex surface is equal to the wall thickness of the steel pipe body. According to the utility model, the annular concave surface symmetrical to the bisection surface of the steel pipe body is matched and clamped with the lifting rope, so that the stability of the connection between the lifting rope and the steel pipe body can be kept, and the risk that the steel pipe falls off due to the separation of the seamless steel pipe from the lifting rope is avoided; and meanwhile, it can be guaranteed that the balance of the steel pipe body is kept in the seamless steel pipe lifting process, the two sides of the lifting rope can be blocked and limited by arranging the sharp corner part and the sharp corner supporting part located on the two sides of the annular concave face, and the stability of connection between the lifting rope and the annular concave face is improved.
