Full face rubber expansion joint is also called large flanged flexible rubber joint, and the end face is fully sealed rubber joint. The product is characterized in that the flange and the end surface of the sphere are all in contact with each other, which not only increases the high pressure resistance of the product. It also played a good role in preventing pull-off.
High elasticity, high elongation, excellent tear resistance and electrical insulation, good wear resistance and drought resistance, good processability, easy adhesion to other materials, and superior to most synthetic rubber in comprehensive performance
The full face rubber expansion joint is characterized by high internal density, high pressure resistance, good elastic deformation effect, shock absorption, noise reduction, light weight and non-toxicity. It is very economical for valves with large connections, pipes with high vibration, and pipes with frequent changes in heat and cold.
A. Compared with mechanical expansion and damping, it takes up less space, is lighter in weight, is easy to install and easy to disassemble, saves labor, and has lower cost.
B. For the same ultimate capacity, it is not necessary to increase the pump and pipe diameter, the inner wall is smooth, the water flow resistance is reduced, and the pipe body parts are not damaged.
C, has a good waterproof sealing, no need to add padding during installation.
D. Wide application range: Different rubber formulas are selected to make the products have various properties such as heat resistance, oil resistance, corrosion resistance, aging resistance, wear resistance and ozone resistance.
E, wide temperature range: reasonable formula (material) can make the product temperature range: -40 ~ 260 °C.
F, long service life: This product can be used indoors for more than 20 years.
Full face rubber expansion joint adopts the flat welding flange, while the ordinary rubber joint adopts the slotted flange. In addition, the edges of the full face rubber expansion joint are the same as the outer edge of the flange, and the flange is installed when the bolt is installed. It is installed inside the edge of the sphere, which greatly increases the pressure resistance, and can generally reach 2.5Mpa or 4.0Mpa. Full face rubber expansion joints are mainly used in the general connection of pipelines or pipelines with displacement requirements, which can play a role in limiting the displacement.
1. Widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire, electricity and other basic projects.
2 Full face rubber expansion joint for indoor installation.
3. Full face rubber expansion joints are suitable for outdoor installation.
4. Full face rubber expansion joint for embedded installation.
