Product advantages:

BF(vssja-1) single-flange limit expansion joint can realize the compensation of axial displacement of pipeline, and can greatly reduce the axial thrust during pipeline operation, so as to extend the service life of pipeline and protect the safe operation of the line. The single-flange loose-bushing limit expansion joint can prevent the leakage or damage of the compensation joint caused by the excessive displacement of the pipeline. It is mainly used to absorb the axial displacement and relieve the axial pressure thrust of the pipeline loose-bushing connection within the allowable displacement range. It realizes the convenient connection of the flange on one side of the pipeline and the inconsistency of the welding on the other side. And installed in the pipeline line can facilitate the disassembly and maintenance of the valve, and can overcome the adverse impact of the pipeline line caused by sinkholes. BF(vssja-1) single-flange limit expansion joint is suitable for conveying seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and powder with temperature no higher than 250 degrees and other media.

Product features:

BF (VSSJA - 1) single flange loose tube limit expansion joint used on one side with the flange connection, and pipe welding, adjust product when installation ends with the installation of the pipe or flange length, diagonal evenly tighten gland bolts, adjust limit nut again, so you can let the pipeline within the scope of scale free expansion, locking expansion amount, to the safe operation of pipeline.

1.Large expansion and long service life.

2.It is convenient to disassemble and assemble the valve, which is beneficial to the regular maintenance of the pipeline.

3.this product can effectively protect the pipeline from the adverse effects of ground subsidence.

4.excellent material, stable operation.
