Double Sphere Flexible Rubber Expansion Joint
Description
The GJQ (X) -SF-I type flexible rubber joint belongs to the double ball type, which is connected with a small edge of the clamping groove type flange. Due to the card slot connection way sealing performance is not as good as the end face full sealing connection, The maximum diameter of GJQ (X) -SF-I type rubber joint can only reach 400mm. And the smallest diameter is 32mm. Compared with GJQ (X) -DF-I type rubber joint, the length for GJQ (X) -SF-I type joint is longer. The flexible rubber joint length for DN32 reaches 165mm, the length for DN400 also reaches 400mm. The same diameter of GJQ (X) -SF-I type rubber joint has larger axial displacement and radial displacement.
Let's use the GJQ DN32 (X) -DF-I type flexible rubber joint and GJQ (X) -SF-I flexible rubber joint as an example to compare. From the inner material and outer material, these two kinds of rubber joints has same material.
Compared with GJQ (X) -DF-I type flexible rubber joint,The length of GJQ (X) -SF-I type has 75mm longer than it, also 24mm elongation larger, 40mm compression larger, radial displacement larger .But deflection displacement of the two are the same, which is 7.5 degrees. It is worth mentioning that the GJQ (X) -SF-I rubber joint of DN32 to DN150 has same radial displacement and deflection displacement, which is 45 and 7 mm. But the axial displacement becomes larger with the increase of the rubber joint length.

Faq
1. Is the flange galvanized?
Yes, carbon steel flange not painting anticorrosive paint must be galvanized in order to avoid rusting. Usually, we choose electronic galvanized and hot dip galvanized, and most of our customers will choose hot galvanizing.
2. What kind of standard of your drilled flange?
Besides Chinese national standard, we also support American standard, German standard, British standard, Japanese standard, European standard and Australia standard. If you can give us the center distance of the hole, the number and diameter, we can also produce customized flange.
3. Does your company have spool type?
Yes, considering that the pipe length will be longer or shorter than the expection after finishing the installation of the pipes and the cost of producing new mold is expensive, we can produce spool type according to your requirements
