Product Description

The galvanized flange rubber expansion joint is mainly made of rubber, and its sphere itself has certain elasticity and flexibility, which is mainly used to absorb the mechanical displacement and thermal displacement of the pipeline system, and reduce and reduce the noise and vibration of the pipeline. It is prohibited to use deformed rubber joints to adjust pipe installation. This will affect the normal service life of the rubber joint compensator and increase the pipeline burden. Due to the special characteristics and advantages of rubber joints, this product is widely used in various pipeline engineering systems.

Excellent sealing performance: it is widely used for its sealing performance. It completely shuts off liquid flow. Small pressure loss: Another benefit of using these valves includes a small pressure loss through the valve. Therefore, it rarely affects the durability of pipes and pipelines.
There are usually three connection methods: flange or screw thread and clamp. Flange connection is commonly used, which is connected as a whole by bolts and nuts, with a certain deflection displacement, so it can be adjusted according to the on-site installation size during installation and maintenance. The axial thrust can be transmitted to the whole pipeline system during operation, which not only helps to improve the work efficiency, but also plays an important role in protecting pumps, valves and other pipeline equipment.

Advantages of rubber expansion joint galvanized flange

The galvanizing process can avoid the time required for on-site spraying after installation. The cost of hot dip galvanizing is relatively low. Of course, the galvanizing process is also faster than the construction of other coatings. Flange galvanizing can make every part of the plated parts be coated with zinc, and the zinc coating forms a special metallurgical structure. This structure is not greatly affected by mechanical damage even when it is transported and used, and can be ground protected even in depressions, sharp corners and hidden places. Because of the reliable durability of this coating, the standard hot-dip galvanizing rust prevention thickness can be maintained for more than 50 years without repair in suburban environments; In urban areas or offshore areas, the standard hot-dip galvanized anti rust coating can be maintained for 20 years without repair. The galvanizing process is faster than the construction of other coatings, and the time required for painting on the site after installation can be avoided. The cost of hot-dip galvanizing is relatively lower.

Spherical joints have a distinct advantage over metallic expansion joints for corrosive applications and installations requiring a high cycle life. The contour prevents sediment accumulation and creates less turbulence and pressure drop than spool joints. The seal bead eliminates any requirement for gaskets between mating flanges. Spheres may be installed on raised-face or flat-face flanges.
