Product overview
It consists of lapped compensating joint and limit expansion pipe, to prevent the leakage or damage of the compensating joint due to excessive displacement. It is a device of lapped joint of pipeline which is used to absorb axial displacement and withstand pressure thrust within the allowable displacement range.
Product characteristics
Double-flange limit expansion joint is composed of main parts such as body, seal ring, gland and short expansion pipe. Limit device is added on the basis of the original performance of the lapped expansion joint, and double nuts are used to lock in the position with maximum expansion or contraction quantity. The pipeline can be expanded and contracted freely in the allowable expansion or contraction quantity, and the limit function will work once beyond its maximum expansion or contraction quantity, to ensure the safe operation of pipeline, especially suitable for the connection in the pipeline with vibration or with certain tilting and bending.
