GJQ(X)-SF-II Double Sphere Flexible Rubber Expansion Joint
GJQ(X)-SF-II Double Sphere Flexible Rubber Expansion Joint use full face connection type, which has better resistance to pressure and leakproofness. It has the performance of heat resistance, acid resistance, alkali resistance, anti-corrosion, wear resistance and oil resistance respectively.
GJQ (x) -SF-II type double sphere flexible rubber joint is similar to GJQ (x) -SF-I type joint, only way to connection way is end full sealed type, which belongs to the large flange rubber joints. Inner layer and outer layer can choose rubber material according to the using environment flexiblely. The skeleton layer is usually use polyester cord and composite rubber, reinforced also by polyester cord. The edge of the reinforced ring in GJQ (x) -SF-II double ball rubber joints use steel wire ring. The rubber layer, ply, steel wire ring can adhesive as a whole after curing.
The diameter of GJQ (X) -SF-II type double sphere flexible rubber joint is commonly in the range of 200 to 3000mm.The two sphere rubber joint for DN200 to DN400 flexible rubber joint can not only use the card slot type but also use seal the end face type. As DN200 rubber joints for example, GJQ (x) -SF-II and GJQ (x) -SF-I type joints has same length. But GJQ (x) -SF-II type double sphere flexible rubber joint has 5mm length elongation, 30mm lager radial displacement of , 2.5 degrees laeger deflection displacement also. This is mainly because the GJQ(X)-SF-II can still maintain high sealing performance in the case of increasing displacement.

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
4. Can the inner layer rubber and outside layer rubber be made using different rubber?
Yes, we can produce the rubber joint according to the environment the rubber joint is used in, and we will choose different rubber for the inner layer and outside layer.
5. Can I only buy ball without the flange?
Yes, and the price will be cheaper. For small diameter rubber joint, we have goods in stock and we can offer you a free hydrotest, but for large diameter rubber joint you need order.
6. How long is your product’s warranty?
12 month. From the day the customer receiving the goods, we grant a free replacement if the products have any problems during the guarantee period.
7. Can you offer the rubber joint sample?
For standard type of rubber joint we can offer the sample, but the customer will afford the freight. For non-standard rubber joint or more quantity, we will charge for the sample.
