The root cause of the weakening effect of the use of bendable rubber joints

The root cause of the weakening effect of the use of bendable rubber joints. Flexible rubber joint pipeline construction and installation, let it be in its natural state, do not artificially in the installation of the product to produce artificial deformation. This can avoid causing early damage to the product and the use of the effect of weakening.
 
Flange bendable rubber joint in the installation, shall make both ends of the sphere to enhance the ring, the protruding part of the inner rigid wire rope, all stuck into the flange groove to prevent the pipeline pressure when the sphere and flange pull off. On the bolt, the first symmetrical bolt, six or four, tighten to ensure that the sphere in the flange of all in place.
 
When using bendable rubber joint for high-rise water supply, the pipeline has fixed support or fixed bracket, otherwise the product should be installed with anti-pull-off device. The force of fixed support or bracket is greater than the axial force, otherwise the product should also be installed with anti-pull-off device.
 
The flexural rubber joint with anti-pull-off device is to ensure the normal operation of the pipeline and prevent the sphere of the flexural rubber joint from being pulled out of the grooved flange by excessive working pressure. The anti-pull-off device, also known as limit anti-pull-off device, is a limit device added to the original product performance, so that the pipeline can be freely expanded and contracted within the allowed expansion amount, and once the expansion amount exceeds the limit to ensure the operation of the pipeline, especially for the connection of pipelines with vibration or a certain slope and bend.
