Claims

[Claims for Utility Model Registration] Annular engaging grooves are formed at each end of a pair of pipes to be connected, and an engaging peripheral portion that engages with these engaging grooves is provided, and the pipes are opposite to each other. A pair of annular semi-annular housings, a ring-shaped gasket attached to the inside of the housing and in contact with the outer peripheral surface of the end of the tube to maintain airtightness or liquidtightness, and a ring-shaped gasket provided at each end of the pair of housings. It consists of a fastening bolt and a nut that fasten the fastening flanges together and fix them to the pipe, and the housing has a concave first fastening surface with two slopes connected in a V-shape on the fastening surface of one fastening flange. A first fastener is provided on the fastening surface of the other fastening flange.
An inverted V-shaped convex second fastening surface consisting of two slopes having the same inclination as each slope of the fastening surface is provided, and the tops of the first fastening surface and the second fastening surface are both aligned with the fastening center axis of the bolt. A pipe joint characterized by being located on the same side offset by different distances from.
