China BFL Flange Type Limited Expansion Joint:

Limited expansion joint is form by adding a limit device to the basic sleeve type expansion joint and locked at maximum expansion by double nut. The pipeline can thus freely in certain limit. When maximum valve id reached, it will be limited and effectively assure the pipeline working safety. Limited expansion joint is especially for pipeline connection where vibration occur, where taper connection requested and for bend pipeline connection.
