The card sets of pipe joints

Is a new pipeline connecting elements , suitable for oil, gas and general corrosive medium pipeline system , working pressure 16-40PMa. Sleeve type pipe joint structure is dominated by Hydraulic tube fittings  tapered hole with 24゜joint body with sharp inner edge of the card sets, play the role of compression nut components. Tighten the nut , the ferrule is pushed 24゜tapered bore, and subsequently deformed , so that the blade cut steel ferrule and the formation of annular grooves , which play a role in sealing . Since the card sleeve and flexible, it can be subjected to greater shocks , played the role of locking .
