Reinforced Rubber Expansion Joint with Control Unit

Product Introduction of Reinforced Rubber Expansion Joint with Control Unit:

The reinforced rubber expansion joint with control unit produced by Songjiang Group adopts forged flanges with cold galvanizing treatment, and is then combined with rubber hoses. For large diameters, our factory installs limit devices to prevent detachment. The high-pressure reinforced rubber expansion joint with control unit plays a role in shock absorption and noise reduction during use, thus protecting the long-term service life of water pump equipment, making it a noise reduction option for many pump rooms.

Explanation of the limit device: Songjiang Group’s produced rubber expansion joint products are all equipped with high-strength limit devices. All screws use grade 8.8 high-strength screws, not comparable to grade 4.8. The ear plates are also widened, enlarged, and thickened. Without comparison, there is no harm. Moreover, we also provide special buffer rubber blocks, which play a role in buffering and noise reduction.
