    • There is disclosed a method of fabricating welded branched pipe connections from weldable thermoplastic materials, such as polyethylene, which includes shaping the end of a branch pipe section to the curvature of a main pipe section, simultaneously heating the shaped end of such branch pipe section and an annular zone of the main pipe section to a welding temperature, pressing the heated shaped end into the heated annular zone of the main pipe section to weld the sections and applying pressure to the material of the sections on both the inner and outer sides of the intersection between the branch pipe section and the main pipe section, while precluding spreading of the sections in a direction perpendicular to the direction in which the sections are pressed together so as to deform the material of the heated annular zone of the main pipe section upwardly into the material of the branch pipe section to increase the area of welding contact. There is also disclosed a press tool for use in such method, which includes outer and inner sleeve means spaced to accommodate a branch pipe section and such sleeves having shaped pressure applying end portions, operative to deform the crosssectional welding line of contact into a raised lip or hump to increase the area of welding contact.
    • 公开了一种从可焊接的热塑性材料(例如聚乙烯)制造焊接的分支管连接的方法,包括将分支管段的端部成形为主管段的曲率,同时加热该分支管段的成形端,以及 主管部分的环形区域到焊接温度,将加热的成形端压入主管部分的加热的环形区域中,以焊接部分并向第二部分的内侧和外侧上的部分的材料施加压力 在分支管段和主管段之间的交叉点,同时防止部分沿垂直于部分压在一起的方向的方向扩展,以使主管部分的加热的环形区域的材料向上变形 分支管段的材料增加焊接面积。 还公开了一种用于这种方法的压制工具,其包括间隔开以容纳分支管段的外部和内部套筒装置,并且具有成形压力施加端部的套筒可操作以使截面焊接接触线变形为 凸起的唇或凸起以增加焊接面积。
