NW Joint, Socket

NW Joint, Socket

• Though various types of mechanical fittings have been developed for absorbing the vibration, deflection, and angle of pipes, there are some disadvantages: they are expensive compared to screw type pipe fittings, and weak against tensile force in the axial directions of pipes.
• JFE NW joints are available to resolve these two disadvantages.
• In comparison with conventional treaded joints, these versatile fittings significantly improve efficiency of pipe installation processes. Simple removal and reinstallation makes repair and facilities expansion processes easier.
