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)-SQ-II flexible rubber joint is a kind of three ball end all sealed rubber joint, flange connection. General specification GJQ(X)-SQ-II is from DN300 to DN3000mm rubber joint size, length range between 450 mm to 650 mm. Elongation displacement to 120 mm, maximum 135 mm compression displacement, maximum radial displacement is 90 mm, maximum deflection displacement plus or minus 10 degrees. Flange material is Q235, GB flange according to GB/T 9119-2010 manufacture. The optional rubber types of inner rubber layer and external rubber cover include: butyl rubber IIR, neoprene CR, EPDM , Natural rubber NR,Butyronitrile rubber NBR.
