Used in the heavy-calibre three direct links , curved and first class mainly, the pipe fittings adopt the butt welding way to process shaping in the factory, working pressure meets the pressure demand for the pipe network , the intensity of material that the intensity of welding seam is higher than the mother, use the security, reliable. Can electricity weld can butt welding join also in connection of pipe network.

    Advantage :

    Corrosion-resistant, longe-lived , light, in charge of being compatible with PE, extendible conservation storage ability
