摘要： There is provided a pipe joint comprising at least one connection end wherein the or each connection end comprises: a wall defining a receiving recess for receiving an end of a pipe length; a tapered locking recess formed in an internal surface of the wall and containing a correspondingly tapered locking element; a through hole in the wall which communicates with the tapered locking recess; and a fixing element rotatable within the through hole and formed with a foot portion. In a first unlocked rotational position of the fixing element the foot is at least partially retracted from the locking recess; and in a second locked rotational position of the fixing element the foot extends into the locking recess to urge the locking element between the tapered locking recess and a pipe located within the connection end.

摘要： There is provided a pipe joint (2) comprising at least one connection end wherein the or each connection end comprises: a wall defining a receiving recess (8) for receiving an end of a pipe length (4); a tapered locking recess (26) formed in an internal surface of the wall and containing a correspondingly tapered locking element (28); a through hole (20) in the wall which communicates with the tapered locking recess; and a fixing element (30) rotatable within the through hole and formed with a foot portion (30c). In a first unlocked rotational position of the fixing element the foot is at least partially retracted from the locking recess; and in a second locked rotational position of the fixing element the foot extends into the locking recess to urge the locking element between the tapered locking recess and a pipe located within the connection end.

摘要： Pipe length comprising a first insert end (2) formed with at least one through slot (26) extending in a direction substantially parallel to a longitudinal axis of the pipe length, a second opposite coupling end (6) for receiving an insert end (2) of a second such pipe length, said coupling end (6) comprising at least one through hole (18) extending from an external surface of the coupling end (6) through to an internal surface of the coupling end (6), a sealing (16,22) arrangement for sealing the insert end (2) of the second pipe length within the coupling end (6) and at least one fixing element (20), the or each fixing element (20) extending through a corresponding one of the through holes (18) in the coupling end (6)and for engaging slideably within a corresponding one of the through slots (26) formed in the insert end (2) of the second pipe length. The arrangement is such that the insert end (2) of the second pipe length is slideable within the coupling end (6) on thermal expansion or contraction of the second pipe length.
摘要翻译：管道长度包括形成有至少一个贯穿槽（26）的第一插入端（2），所述至少一个通孔（26）沿着基本上平行于管长度的纵向轴线的方向延伸;第二相对的联接端（6），用于接收插入端），所述联接端（6）包括从所述联接端（6）的外表面延伸到所述联接端（6）的内表面的至少一个通孔（18），密封件（16,22）布置，用于密封联接端（6）内的第二管长度的插入端（2）和至少一个固定元件（20），所述或每个固定元件（20）延伸穿过相应的一个连接端（6）中的通孔（18），并且用于可滑动地接合在形成在第二管道长度的插入端部（2）中的相应的一个通孔中。该布置使得第二管道长度的插入端（2）在第二管道长度的热膨胀或收缩下可在联接端（6）内滑动。
