Description
Single flange limit expansion joint is loose tube expansion joints and limit short tube and other components. It can prevent the pipe due to excessive displacement lead to the compensation joint leakage or damage, mainly for the axial displacement within the allowable displacement range and the pressure to withstand the pressure of pipe loose connection, suitable for side flange connection, while welding with the pipe , Adjust the installation of both ends of the product and the installation of pipe or flange length diagonal diagonal screw gland bolts in turn, and then adjust the limit nut, so that you can make the pipeline within the range of telescopic free expansion, locking the amount of expansion, Ensure the safe operation of the pipeline
