AI Technical Summary

Technical Problem

Existing seamless steel pipes are mostly connected by bolts, which takes a long time to connect, affecting installation efficiency. Furthermore, the connection is not very firm and is prone to loosening during fluid transport vibration. The support strength is also low and it is easy to deform.

Method used

A seamless steel pipe with a connection mechanism was designed, including a support frame, extrusion rod, limit buckle, extrusion table, clamping groove, connecting table, positioning groove and reinforcing ring. These structures enable rapid docking, positioning and locking, and enhanced support, thereby improving docking efficiency, firmness and support strength.

Benefits of technology

This technology enables rapid connection of seamless steel pipes, improves installation efficiency, ensures the strength of the connection, reduces the probability of deformation under pressure, and ensures the normal transport of fluids.

Abstract

According to the technical scheme, the seamless steel pipe with the connecting mechanism comprises a pipe body and a supporting frame, the supporting frame is installed on the outer surface of the pipe body, a clamping rod is installed in the supporting frame, an extrusion table is installed at the bottom of the clamping rod, a clamping groove is formed in the side, away from the supporting frame, of the outer surface of the pipe body, and the extrusion table is installed in the clamping groove. A positioning frame is mounted at the top of the supporting frame, an extrusion rod is mounted in the positioning frame, a limiting buckle is mounted at the tail end of the extrusion rod, an extrusion spring is mounted on the outer surface of the extrusion rod and located in a gap of the limiting buckle, and limiting teeth are arranged on the side, close to the limiting buckle, of the clamping rod. The seamless steel pipe with the connecting mechanism solves the problems that the butt joint time of the seamless steel pipe is increased and the installation efficiency of the seamless steel pipe is affected due to the fact that the existing seamless steel pipe is connected by adopting a bolt connection mode during use and the butt joint connection needs much time, the butt joint efficiency of the seamless steel pipe is improved, and the production cost is reduced. Therefore, the installation efficiency of the seamless steel pipe is ensured.
