Abstract | To provide a pipe joint capable of achieving both tensile strength and tensile fatigue strength while an increase in insertion force of a pipe is suppressed by adjusting a ring width of a coming-off prevention ring and a spacer width.SOLUTION: A pipe joint includes: a joint body; an annular packing arranged on an inner peripheral surface of the joint body; an annular base 103b arranged on the inner peripheral surface of the joint body; an annular spacer 104c arranged on the inner peripheral surface of the joint body; a first coming-off prevention ring 104a arranged on the inner peripheral surface of the joint body; and a second coming-off prevention ring 104b arranged on the inner peripheral surface of the joint body. The first coming-off prevention ring 104a and the second coming-off prevention ring 104b have a plurality of crimping teeth on the inner periphery, and a proportion of width of the spacer 104c and widths of the first coming-off prevention ring 104a and the second coming-off prevention ring 104b is between 0.5 and 0.8.SELECTED DRAWING: Figure 4
【課題】抜け止めリングのリング幅とスペーサー幅を調整することで、パイプの挿入力の上昇を抑えつつ、引張強度及び引張疲労強度が両立可能な管継手を提供することを目的とする。【解決手段】継手本体と、前記継手本体の内周面に配置された環状のパッキンと、前記継手本体の内周面に配置された環状のベース103bと、前記継手本体の内周面に配置された環状のスペーサー104cと、前記継手本体の内周面に配置された第1の抜け止めリング104aと、前記継手本体の内周面に配置された第2の抜け止めリング104bと、を備え、前記第1の抜け止めリング104aおよび前記第2の抜け止めリング104bは、内周に複数の食い込み歯を有し、前記スペーサー104cの幅と、前記第1の抜け止めリング104aおよび前記第2の抜け止めリング104bの幅との比が、0.5~0.8である管継手。【選択図】図4 |
