Flange Choosing of Rubber Expansion Joint
Rubber joint is made of inside and outside layer of glue, ply and a steel wire ring which composed of tubular rubber parts, after vulcanization molding combine with metal flange. This product can reduce vibration and noise, and the thermal expansion due to temperature change caused by the shrinkage compensation action.
It is widely used in a variety of pipe system. The choice of rubber joint flange is very particular, the user should not only be able to learn to distinguish the good or bad of the flange, but also according to the product's installation environment to choose the flange type.
At this stage, the flange on the market in accordance with the production process can be classified as forging and casting type, forging flange surface is smooth, casting process of flange in the inner side of the ring parts will appear holes, so this type flange oxidation degree will faster, working life is not as long as forged flange. So the user in the purchase of the flange must draw a distinction between them and avoid buying inferior flange products, which may caused immeasurable loss to their own projects.
Except that, users also need to according to its own pipeline installation environment with appropriate pressure rubber joint flange, flange pressure is 1.0MPa and 1.6Mpa, these two types of flange basically can meet at this stage most of the pipeline installation environment. For special circumstances, the pipeline operating pressure is higher, XINLI Pipeline Equipment Co.,Ltd as a professional manufacturer of rubber joints we can supply higher pressure flange for better performance according to the user's actual requirements in production.
