VSSJA-2 type double flange limit expansion joint

Double flange limit expansion joint VSSJA-2 or B2F type, the connection method of flanges on both sides of the pipeline. The double flange limit expansion joint can be installed on the pipeline to connect with valves. The double flange limit expansion joint not only compensates for the expansion of the pipeline but also provides convenience for valve maintenance The double flange limit expansion joint is composed of a loose sleeve and a flange limit short pipe. The double flange limit expansion joint can prevent leakage and damage of the compensating joint caused by excessive displacement of the pipeline. The double flange limit expansion joint is mainly used for loose sleeve connection of pipelines that absorb axial displacement and bear axial pressure and thrust within the allowable displacement range

Brief installation instructions for double flange limit expansion joint: VSSJA-2 type double flange limit expansion joint is suitable for connecting both sides to flanges. When installing the double flange limit expansion joint, adjust the connection length between the product's two ends and the flange, tighten the gland bolts evenly diagonally, and then adjust the limit nut. This way, the double flange limit 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.
