Document Type and Number:
WIPO Patent Application WO/2015/075966
Kind Code:
A1
Abstract:
[Problem] To provide a pipe joint structure for which a gap that would enable the infiltration of a fluid being transported between the inner circumferential surfaces of coupled pipe elements is not generated. [Solution] A pipe joint structure having a first and a second pipe element which are coupled to each other. The first pipe element has a first sharp-angled seal part, which is defined by a first inner circumferential surface (defining the hole of the first pipe element) and a first annular surface that extends radially outward from an end edge (a first end edge) of the first pipe element, and the second pipe element has a second seal part, which is defined by a second inner circumferential surface (defining the hole of the second pipe element) and a second annular surface that extends radially outward from an end edge (a second end edge) of the second pipe element. The first and second pipe elements are coupled to each other by bringing the first end edge and the second end edge into contact with each other.
