BF single flange limit expansion joint is a combination of loose sleeve expansion joint and a limit short pipe. Single flange loose sleeve limit expansion joints are used to connect one side to the flange and the other side to be welded to the pipeline. During installation, adjust the installation length between the two ends of the product and the pipeline or flange. Tighten the gland bolts diagonally, and then adjust the limit. Nuts, so that the pipeline can be freely expanded and contracted within the range of expansion and contraction, and the expansion and contraction can be locked, and the pipeline can operate safely.
