The following matters should be noted when installing rubber joints:
 
1 . It is strictly forbidden to exceed the displacement limit of the bendable rubber joint when installing.
2 . Install the bolts symmetrically and tighten them gradually with pressure to prevent local leakage.
3 . When installing rubber joints on flat ground, in the air or vertically, the actual working axial displacement pressure of rubber joints should be less than the supporting force of the pipeline, otherwise anti-displacement devices should be installed to prevent the work from being delayed under pressure.
4 . Rubber joints should be kept away from heat source and ozone zone, and strong radiation light is strictly prohibited. Exposure to sunlight and the use of media that are not suitable for this product.
5 . When transporting, loading and unloading, installing rubber joints, it is strictly forbidden to scratch the surface sealing surface with sharp tools.
6 . When installing products above DN200MM, please use special flange for butterfly valve or small diameter flange to avoid flange pull off, water leakage and water seepage after installation.
 
Rubber joint is also called rubber soft joint, flexible rubber joint, shock absorbing throat, shock absorber. It is vulcanized under high temperature. Both ends are steel flanges. There are grooves on the flange surface. The rubber ball can be fastened in the flange groove to prevent pulling off. The general pressure is 0.6MPa, 1.0MPa, 1.6MPa. If the pipeline displacement force is large, it is necessary to install anti-dislodgement limit device on the flange. When the pipeline pressure is too large, you can choose full sealing surface rubber joint, commonly known as full-edge rubber joint. We specialize in producing 50MM--2200MM full-sided spheres, which are better sealed, more pressure resistant and longer lasting.
