发明名称 PIPELINE CONNECTION, PIPELINE JOINT AND HYDRAULICALLY OPERATED APPARATUS FOR MAKING PIPELINE JOINTS
摘要 The pipe joint proposed includes a connector (1) with at least one spigot (2, 2', 2") on which the end (6) of a pipe made of thermoelastic, cross-linked polyolefin is fixed by opening out and self-reforming to form a secure, gastight joint. The spigots (2, 2', 2") have a surface feature (3, 3', 3") and, beyond it, an extension (4, 4', 4") with chamfered end (5, 5', 5").
