GJQ(X)-DF-I Single Sphere Flexible Rubber Expansion Joint
Product Description
Flexbile rubber joint consists of rubber body and metal flanges or screw thread, which is used in metal pipe system for vibration isolation, reducing noise and displacement compensation. Flexible rubber joint also called rubber joint, rubber expansion joint , flexible joint, is a kind of pipeline system joint which has the performance of high elasticity, high air-sealed, media resistance and weather resistance. The rubber flexible joint consists of inner layer rubber, reinforcing layer with polyester cord fabric and outside layer rubber with compounded rubber pipeline. According to different media, it will use different rubber, including natural rubber, butadiene-styrene rubber, butyl rubber, butadiene-acrylonitrile rubber, EPDM, chloroprene rubber, silicone rubber, fluorous rubber and so on. And they have the performance of heat resistance, acid resistance, alkali resistance, anti-corrosion, wear resistance and oil resistance respectively.

GJQ(X)-DF-I type flexible rubber joint is a kind of single sphere small edge along the card slot type flexible rubber joint. " DF" in the " GJQ(X)-DF-I " shows a single sphere, and "I" refers to the small along the card slot type. A small edge along the card slot type is on the opposite(side)of the end face of the full sealed rubber joint. The edge of this type rubber joint is relatively narrow, and only extends to the inner edge of the flange bolt hole.

GJQ (x) -DF-I type rubber expansion joint can choose any kind of inner layer rubber material and outer material,such as IIR, CR, EPDM, NR, NBR and so on. The external and internal layers of rubber material can be different. But skeleton layer of rubber joint are produced by polyester fabric and enhancement layer has a steel wire ring. Flange material is also diverse, common material is like Q235 SS304 and SS316. Flange Standard is also varied, different countries have different standards and commen standard is like GB standard, ANSI Standard, DIN standard.

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.
8. Does the rubber joint have inspection report?
Yes, all of our product will be conducted hydrotest and leave the factory with a qualified inspection report.
9. Can you offer the drawing?
