GJQ(X)-SQ-II Three Sphere Flexible Rubber Expansion Joint
GJQ(X)-SQ-II Three Sphere Flexible Rubber Expansion Joint is three sphere full face type rubber joint, it’s sphere is a recombination of inner & outer glue line and enhancement layer. It has the performance of high-elasticity, high gas tightness, medium resistance and weather fastness.
GJQ(X)-SQ-II flexible rubber expansion joint is a kind of three sphere end all sealed rubber expansion joint with flange connection. 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.
General size of GJQ(X)-SQ-II is from DN300 to DN3000mm, length range between 450mm to 650mm. Elongation displacement to 120 mm, maximum 135mm compression displacement, maximum radial displacement is 90mm, maximum deflection displacement plus or minus 10 degrees. The optional rubber types of inner rubber layer and external rubber cover including: butyl rubber IIR, neoprene CR, EPDM, Natural rubber NR, Butyronitrile rubber NBR.
Lanphan production with naturaland synthetic rubber,rubber joint ball for rubber hue,volatile,vulcanization characteristics,such as strict test were carried out before the purchase,power source to eliminate the hazard and eliminate defects.
The flange made by Lanphan meet the international standard of DIN, ANSI,ASME, JIS,BS,EN and other standards, our flange thickness, smooth surface roughness, the accuracy of the caliber are within the tolerance of control thousand classification.
Lanphan’s rubber joint brief paragraph internal coil with high quality metal wire, can effectively improve the tensile stress ability of the port, and cross section sealing layer is bigger than other manufacturer, mainly in order to increase the contact area, improve the sealing performance.
