Title:

RESIN PIPE JOINT

Document Type and Number:

WIPO Patent Application WO/2000/028251

Kind Code:

A1

Abstract:

A resin pipe joint comprising a flare portion (10a) formed on a pipe (10), an inclined portion (11a) formed internally of a joint body (11), an annular member (12) having inner peripheral surface fitted on the pipe and the outer peripheral surface inserted in the joint body and formed at the end with a tapered chamfered portion (12a), and a pipe clamping member (13) threadedly fitted to the joint body. The pipe clamping member being threadedly fitted to the joint body causes the chamfered portion of the annular member to pressure-contact the flare portion of the pipe and the flare portion of the pipe to pressure-contact the inclined portion in the interior of the joint body, whereby the clamping force can be concentrated on the flare portion of the pipe, so that a high sealing capability between the pipe and the joint body is obtained.
