Product Introduction
GJQ(X)-DF-II 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-II type single sphere flexible rubber joint is a kind of single sphere end face full sealing flexible rubber joint. " DF " in the " GJQ (X) -DF " shows a single sphere, and "II" refers to the end of the whole seal. A small edge along the card slot type is on the oppositesideof the end face of the full sealed rubber joint. The edge of the rubber joint is relatively wide, which has been extended to the outer edge of the flange.Above the outer edge of the rubber joint ,there are bolt holes corresponding to flange.

GJQ (x) -DF-II type single sphere flexible rubber joint has same inner layer and outer layer rubber material with GJQ (x) -DF-I type flexible rubber joint,which can choose any kind of rubber 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, JIS standard ,ANSI Standard, DIN standard.GB flange standard can use GB/T 9119-2010 as a reference.
