  • Electric fusion piping materials with screw pressing device
    Patent number: 7798531
    Abstract: An electric fusion pipe coupling is adapted for bonding with plastic pipes by electric fusion. The pipe coupling can convert the rotation of a pressing member into linear motion by threads to directly or indirectly press a heating element provided in the inner periphery of a pipe joint of the pipe coupling in order to press melting parts heated by the heating element, thereby producing pressure necessary for fusion bonding as well as eliminating an interface of impurities, thereby enhancing fusion efficiency.
