摘要:
Provided is a housing type pipe joint to enable the confirmation of an appropriate fastening degree of a joint and reduce a load of a fastening work. The housing-type pipe joint includes a pair of joint segments, an elastic seal ring, and a fastening means fastening the pair of joint segments, in which the joint segments each have an arc portion, flange portions extending from both ends of the arc portion, a concave groove formed in an inner peripheral surface of the arc portion to have the elastic seal ring fit therein, and in which the fastening means makes the flanges of the both joint segments approach each other to make the arc portions bend so that radii of curvature of the arc portions become smaller, and when, as a result of the bending, peripheral edges of the arc portions match outer surfaces of the pipes that are to be coupled, the coupling of the pipes is completed, the housing-type pipe joint including marks on the peripheral edge regions of the arc portions, wherein, when the peripheral edges of the arc portions corresponding to the marks come into contact with the outer surfaces of the pipes, the coupling of the pipes is completed.
