Casing pipe for pipe connection

The invention discloses a casing pipe for pipe connection. The casing pipe is designed to save pipe connecting time to the maximum degree and provide excellent support for pipe construction and operation. According to the casing pipe for pipe connection, the inner diameter of the casing pipe is equal to the outer diameters of pipes; a circumferentially assembled annular groove is formed in the inner circumferential surface of the casing pipe, and a rubber sealing ring and a compression steel ring are arranged in the groove; axial holes communicated with the circumferentially assembled annular groove are respectively formed in the two end faces of the casing pipe, a compression bolt is connected into each axial hole, and the tail portion of each compression bolt abuts against the compression steel ring; radial through holes are formed in the two ends of the outer circumferential surface of the casing pipe, a grasping bolt is connected into each radial through hole, and the rail portions of the grasping bolts abut against the outer circumferential surfaces of the pipes inserted into the casing pipe from the two ends of the casing pipe. According to the casing pipe for pipe connection, the interconnection between pipe sections is achieved through the casing pipe, fast connection of pipe connectors can be achieved, the joint difficulty is reduced, and the pipe connecting time can be saved to the maximum degree. The casing pipe for pipe connection is a beneficial means for quickening the pipe construction and operation. With the development of oil and gas pipeline construction, the device will play a more important role.
