The press fit limit expansion joint is a new product that adds a limit device on the basis of the original function of the loose fit expansion joint. It can be locked with double nuts at the maximum expansion amount. In this way, the pipeline can freely expand and contract within the allowed range of expansion and contraction. Once it exceeds its maximum expansion and contraction, it plays a limiting role. During installation, first loosen the gland nut, adjust it to the installation length, and then weld the short pipes at both ends to the pipeline or connect them with flanges. Finally, tighten the nut evenly using diagonal method and adjust the anti pull nut.
