Abstract
PURPOSE: To seal the outer and inner surfaces of the end portion of the steel pipe and corrosion preventively fix the end surface thereof by inserting an end of the steel pipe having corrosion preventive lining into the body of the pipe coupling, pressing and engaging it with the outer periphery of a core seal ring, and having the diameter of the end of the pipe coupling body degraded with respect to the outer side. CONSTITUTION: When a steel pipe 44 having corrosion preventive lining is connected to a corrosion preventive pipe coupling 43, an end of the steel pipe 44 having corrosion preventive lining is inserted into the body 30 of the pipe coupling, pressed and engaged with the outer periphery of a core seal ring 34, then the outer annular protrusion 38 of the body 37 of a cylindrical rubber 41 is compressed to seal the inner periphery of the steel pipe 44 having corrosion preventive lining. The end surface of the steel pipe 44 having corrosion preventive lining is pressed to contact the side of the thick portion 39 of the cylindrical rubber 41 to prevent corrosion. The diameter of the outer periphery at the end portion of the body 30 of the pipe coupling is degraded by a press tool to bite into the outer periphery of the steel pipe 44 having corrosion preventive lining. In the meantime, the diameter of the steel pipe 44 having corrosion preventive lining is also degraded and fixedly connected.
