    • Pipe fittings for joining piping materials have a main body with a substantially equal diameter to that of the piping materials to be joined, an annular expanded portion formed at least at one end portion thereof and enlarged diameter portions on each side of the annular expanded portion. The piping materials are joined by inserting them into the pipe fittings and by pressing the outer enlarged diameter portion along the circumference at an end portion thereof to subject the enlarged diameter portion and the piping materials to plastic deformation. By virtue of recesses formed at the pressed portions, the pipe fittings and the piping materials are firmly fixed together. A tapered portion provided at the end of the pipe fittings effectively increases the slip-off checking force, and also the Joint can be perfectly sealed by the sealing material received in the internal space of the annular expanded portion, having been deformed by the application of pressing. Crevice corrosion can completely be prevented since an adequate clearance is defined between the non-pressed enlarged diameter portion and the piping materials inserted into the pipe fittings.

    • A method of joining a pair of pipes is disclosed. The method includes forming one of the pipes with an enlarged diameter near one end thereof. A radially-outwardly flared section widens from the enlarged diameter toward the end of the pipe. An elastic gasket and a C-shaped rigid ring are placed in the flared section. A second pipe is then inserted inside the enlarged section of the first pipe. The outer pipe is then inwardly deformed by the action of a pressure member, such as the die, applied to the exterior of the outer pipe in the region of the pipe overlap. The free end of the outer pipe deforms plastically inwardly toward the inserted pipe thereby compressing the gasket into sealing engagement between the two pipes and compressing the C-shaped ring. As the C-shaped ring is compressed, the outer pipe is deformed into the inserted pipe so that the ring is engaged by the inner wall of the outer pipe and is wedged into the outer wall of the inserted pipe.
    • 公开了一种连接一对管道的方法。 该方法包括在其一端附近形成具有增大直径的管之一。 径向向外扩张的部分从扩大的直径朝向管的端部变宽。 弹性垫圈和C形刚性环放置在扩口部分。 然后将第二管插入第一管的扩大部分内。 然后外管通过在管道重叠的区域中施加到外管外部的压力构件(例如模具)的作用而向内变形。 外管的自由端朝向插入的管道塑性变形,从而将垫圈压缩成两个管道之间的密封接合并压缩C形环。 当C形环被压缩时,外管变形成插入管,使得环与外管的内壁接合并楔入插入管的外壁。
