Overview: 

 The sleeve nut is the core driving part of the sleeve pipe joint. Through thread meshing, the front sleeve and rear sleeve are pushed to produce radial extrusion, and finally realize the fixation and sealing of the metal pipe. It is the key hub for connecting the "metal pipe" and the "joint body". Its structural design focuses on the optimization of "uniform force transmission", "anti-loosening and earthquake resistance" and "adaptation to card sleeve action". It is widely used in the connection scenarios of small-diameter metal pipes (outer diameter φ4~φ32mm) such as instrument pipelines, hydraulic systems and chemical equipment. It is adapted to medium and low pressure (conventional PN≤32MPa), wide temperature ( -200℃~600℃) working conditions.
