Product Introduction
Expansion joints are mainly used in installation and maintenance, adjusted according to the size of the on-site installation, and can return the axial thrust to the entire piping system during operation. This not only improves work efficiency, but also plays a certain role in protecting pipeline equipment such as pumps and valves.
Product Advantages
1. Gland: Thickened pressure plate is adopted, and steel ring is added to the pressure plate part, so that the sealing ring is not exposed, and the quality and beauty are improved.
2. Middle plate: In order to ensure the exquisite appearance, the middle plate is finely turned, and its outer circle is formed into a straight line.
3. Nuts: The size of all bolts and nuts is customized according to the standard flange holes, which are anti-pull-off.
4. Welding: After the body flange is welded, it is finished turning, and there are no sand holes and cracks inside the weld to ensure the normal operation of the expansion joint.
5. Grinding: In strict accordance with the welding standards, the weld is wide and uniform, and the welding is manually polished after welding, and there is no welding slag in appearance.

Product installation and maintenance
When installing, the double flange limit expansion joint is suitable for connecting with the flange on both sides, adjusting the installation length of the product at both ends and the pipe or flange, tightening the gland bolt evenly diagonally, and then adjusting the limit nut, so that the pipeline can be freely expanded and contracted within the expansion and contraction range, and the expansion and contraction amount can be locked to ensure the safe operation of the pipeline. In the process of use, it is necessary to consider the working pressure, temperature, medium and other factors of the pipeline to ensure that the expansion joint can adapt to the working conditions of the pipeline.
