Introduction
The same or different pipe diameters, the same kind or different kinds of metal pipes to be connected are inserted in the form of inner and outer pipes, and the connection gap between the containing pipe and the contained pipe is filled by our company's special The developed sealing fluid pushes the
quick-closing ring forward with external power and compresses the two butt joints in a radial direction uniformly, forcing plastic and elastic deformation of the connecting part of the pipeline, so that they tightly form a metal-to-metal sealing surface. The small gaps and scratches between the inner and outer pipes are filled and sealed, completely sealing all axial leakage channels. The centripetal force generated by the quick-closing ring locks the connection part. The connected containment tube extends 2-5 mm from the quick-closing ring to make the connection part tight. The tube is filled with 1.6MPa air pressure, and the connection part will not leak,and its life is the same with pipes .
