Gongyi Xinli Pipeline Equipment Co.,Ltd.

This product is used to modulate the product's length between flange and the pipe while installing. Screw down bolt, and then adjust the nuts so that the pipe can expand and contract freely within the scope. Fix the scope to guarantee fail safe operation of the pipe. Limited Telescopic Joint is formed 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 expand in certain limit. When maximum valve is reached, it will be limited and effectively assure the pipeline working safety. Limited expansion joint is especially suitable for pipeline connection where vibration occur, where taper connection requested and bend pipeline connection.
