SF Steel expansion jointDetailed product description：

SF steel expansion joint is composed of a loose sleeve and a flange limit short pipe combination. It can prevent leakage and damage of the compensating joint caused by excessive displacement of the pipeline. Steel expansion joint is mainly used for loose sleeve connection of pipelines that absorb axial displacement and bear axial pressure thrust within the allowable displacement range Steel expansion joints are suitable for connecting both sides to flanges. When installing steel expansion joints, adjust the length of the connection between the product's two ends and the flange, tighten the gland bolts diagonally and evenly, and then adjust the limit nuts. This way, the steel expansion joint can allow the pipeline to expand and contract freely within the expansion range, lock the expansion amount, and ensure the safe operation of the pipeline.
