Description

Technical Field

[0001] The present application relates to the technical field of butt joints, and in particular to a pipe joint butt joint. Background Art

[0002] Composite pipe is a common pipe material, which has good corrosion resistance, pressure resistance, structural strength, etc., and has important applications in the fields of fluid transmission. In the process of assembling the composite pipe flow system, multiple composite pipes need to be docked. In the prior art, the docking of composite pipes is usually done by manpower. When docking large-diameter pipes, due to the large pipe diameter and large ring stiffness, the docking process is more laborious and requires more manpower for a long time to complete. However, sometimes the working space is small and cannot accommodate multiple people to operate at the same time, which increases the difficulty of docking, reduces the efficiency of composite pipe docking and delays the entire construction process, so it needs to be improved.
