GJQ(X)-4Q-ⅡFull Face Type Four Sphere Rubber Expansion Joint
GJQ(X)-4Q-II and GJQ(X)-SQ-II are all full-seal rubber expansion joint with flange connection, same rubber material, as well as same flange standard. While GJQ(X)-4Q-II rubber flexible joint has larger diameter, and can compensate much more axial/lateral/angular displacement, so that inhibiting device would be suggest to add on or fixed support should be installed on pipe connecting the joint of each side.
The name of GJQ(X)-4Q-II rubber flexible rubber expansion joint added inhibiting device has some differences. For example, 2800KTGJQ(X)-II-4Q means four-sphere rubber flexible joint with diameter of 2800mm and added adjustable inhibiting device. Its length is 700mm, maximum expansion is 170mm , compression is 200mm, the maximum radial displacement is 100mm, the angular displacement is 10°.
GJQ(X)-4Q-II rubber flexible rubber expansion joint using notes: when it applied to water supply in high building, fixed support or bracket is necessary.
