Fuzhou expansion joint in the demolition and replacement of a number of matters to pay attention to

Fuzhou Telescopic joint There are many things to pay attention to when replacing


The expansion joint is developed and manufactured on the basis of the well-known pig iron expansion joint. Compared with the pig iron material, the expansion joint not only prevents water seepage such as sand hole, but also has better high pressure resistance characteristics when solving the high pressure power supply pipeline. After that, the development trend of the expansion joint is more common The product series of anti-corrosion expansion joint, anti pull off expansion joint, steel limit switch expansion joint, steel force transmission products and other product series have been developed. Since the material of this commodity is steel, it is also called expansion joint.

Expansion joint is also called soft expansion joint in many cases. How can it be called soft expansion joint?
After dismantling the expansion joint, it is found that there is a silicone ring in its interior. In the whole application process of the expansion joint, the material of the expansion joint itself is made of steel In view of the natural environment hazards have a certain resistance, but vulcanized rubber materials or can not solve the years of oxidation erosion, it is inevitable that there will be leakage and water seepage, if the best maintenance stage is delayed, it will lead to incalculable adverse effects in normal operation. In order to better prevent this kind of situation, inspection should be carried out on time

When it is found that the silicone rubber ring is not very good, it is necessary to immediately dismantle and replace it. Pay attention to a lot of matters. The expansion joint should not be reversed for a long time. The hexagon bolt should be placed in a conspicuous area to prevent loss. If rust stains are found on the rubber ring groove, it must be removed. When the new rubber ring is placed in the best position, please assemble the expansion joint according to the disassembly process. After proper installation, the anchor bolts should be pressed evenly to prevent deformation caused by uneven bearing force or excessive bearing force of rubber ring.
