Product advantage:
The VSSJA-1(BF) single-flange limit expansion joint can compensate the axial displacement of the pipeline and greatly reduce the axial thrust of the pipeline during operation, thus extending the service life of the pipeline and protecting the operation of the line. We believe that what is best for our customers is best for us, Zhongyuan valve fittings reminds Monrovia friends to understand this information: The single flange limit expansion joint can prevent the leakage or damage of the compensation joint due to the excessive displacement of the pipeline. It is mainly used for the loose sleeve connection of the pipeline to absorb the axial displacement and relieve the axial pressure thrust within the allowable displacement range. If there is an order is also a mistake, then we let you wrong to the end, Zhongyuan valve fittings reminds Monrovia friends that this information is valuable: It realizes the convenient connection of one side of the pipe flange connection and the other side for the inconsistency of welding. And installed on the pipeline line can facilitate the disassembly and maintenance of the valve, and can overcome the bad influence of subsidence on the pipeline line. VSSJA-1(BF) single flange limit expansion joint is suitable for conveying sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, temperature is not higher than 250 degrees of steam and granular powder and other media.
Product characteristics:
VSSJA-1(BF) single flange limit expansion joint is used to connect with the flange on one side and weld with the pipe on the other side. During installation, adjust the installation length of both ends of the product and the pipe or flange, tighten the gland bolt diagonally evenly, and then adjust the limit nut. Every part counts, Every penny counts, Key points of product knowledge in the field of coal gas: In this way, the pipe can be expanded freely within the scope of expansion, lock the expansion and the maximum operation of the pipe.
1. large expansion, long service life.
2. convenient valve disassembly, conducive to the pipeline regular maintenance.
3. This product can effectively protect the pipeline from the adverse effects brought by subsidence.
4. excellent material, stable operation.
