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.Product Alias:Flexible Rubber Joint,Rubber Joint,Rubber Soft Connection,Shock Absorber,Flange Soft Connection,Flexible Rubber Joint,Rubber Pipe Joint,Compensator,etc Product Specifications: DN32mm - DN3600mm Product Pressure: 0.6-2.5 MPa Level of Shock Absorption: A level, shock absorption is very high Product Certification: ISO9001:2008 Scope of Application: acid, alkali, corrosion, oil, hot and cold water, compressed air, compressed natural gas, etc Product Color: black, physical color see goods display pictures Working Temperature: 15-115 ℃ (ordinary) / - 30-250 ℃ (special)
