What do you know about VSSJA-1(BF) single flange limit expansion joint?
BF type single flange limit expansion joint is composed of components such as loose sleeve expansion joint and limit short pipe. It can prevent the leakage or damage of the compensation joint due to excessive displacement of the pipeline, and is mainly used for the loose-fitting connection of the pipeline that absorbs axial displacement and withstands pressure thrust within the allowable displacement range, and is suitable for connection with the flange on one side and welding with the pipeline on the other side. This allows the pipe to expand and contract freely within the expansion range, locking the expansion amount and ensuring the operation of the pipe.
Principle of operation: After the loose sleeve expansion joint is installed on the pipeline, the nut is tightened and the elastic seal is tightly pressed on the outer ring of the pipe under the action of the nut and gland, relying on the mutual slope to seal and connect the role. When the temperature changes, the pipe is free to expand and contract in the middle of the joint, and when the foundation sinks, the pipe can be deflected, and ensure the seal without leakage, thus playing the purpose of automatic compensation. It is suitable for connecting with flange on one side and welding with pipeline on the other side. The installation is to adjust the installation length of both ends of the product and the pipe or flange. After installation and welding, the gland bolts are evenly tightened diagonally at one time, so that it becomes one and has a certain displacement, which is convenient to adjust according to the site size during installation and maintenance. When working, the axial thrust can be transferred to the whole pipeline.
VSSJA-1 type single flange limit expansion joint is suitable for connecting with flange on one side and welding with pipeline on the other side. When installing, adjust the installation length of both ends of the product and pipeline or flange, tighten the gland bolts diagonally and evenly in turn, and then adjust the limit nut, so that the pipeline can expand and contract freely within the expansion volume, lock the expansion volume and ensure the operation of pipeline. Single flange limit expansion joint is suitable for conveying seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, steam with temperature not higher than 250 degrees and granular powder and other media.
