Background
In the field of medium-high pressure pipelines, the butt joint of two sections of pipelines is mainly realized by adopting flange, clamp and other modes at present. Whether flange connection and clamp connection are adopted, welding and threaded connection are adopted, the welded seam is easy to leak after the flange and the joint welded by the pipeline are welded, the epoxy of the pipeline can be damaged due to high temperature during welding, the anti-corrosion requirement cannot be met, if the flange is welded firstly and then anti-corrosion is carried out, the anti-corrosion difficulty of the flange part is high, if the welded seam is difficult to repair due to leakage, and the anti-corrosion requirement is also difficult to reach after repair.
If the pipeline is connected in a threaded mode, the internal and external anti-corrosion layers are required to be destroyed in threaded connection of the pipeline, or the pipeline is connected with the joint before the pipeline is corroded, then the pipeline is corroded, the high temperature in the corrosion prevention process can damage the sealant of the threaded connection, the sealing performance is poor, and in addition, the leakage of the thread is found to be unable to repair.
And traditional flange joint or clamp connection all need be with two pipelines after the alignment of completely aligning earlier, reuse clamp or screw locking still can appear the pipeline skew condition in locking process, just can accomplish the pipeline butt joint with the alignment just so many times, and installation rate is slow, and installation accuracy is poor.

However, the technical scheme has the following biggest defects: the pipelines butted by the scheme cannot convey highly corrosive media, and the reason is that: after the butt joint of the technical scheme, the sealing ring arranged at the butt joint surface of the male connector and the female connector is utilized to realize sealing, so that a medium can directly contact the inner wall of the pipeline and the joint (the male connector and the female connector) and the butt joint of the joint (the male connector and the female connector) during conveying, and corrosion can be caused to the pipeline and the joint. If the pipeline and the joint are made of nonmetallic anti-corrosion materials, the strength requirement cannot be met, so that the technical scheme capable of realizing rapid and high-precision butt joint of the pipeline and high-corrosiveness medium conveying is designed, and the technical scheme is a problem to be solved in the field.
