Xinli Flange is a very important part of rubber joints. Xinli Flange is used to connect pipe to pipe. Xinli Flange can be divided into many kinds.The special flanges for flexible rubber joint are generally forged or casted with grooved shape, with less flat welding flanges. Gongyi Xinli flexible rubber joint special flange has such characteristics: corrosion resistance, acid and alkali resistance, long lifetime. Flexible rubber joint has reasonable price , smooth surface, beautiful appearance. There are differences between the commonly used flexible rubber joint flanges: the characteristics of forging flange are anti-corrosion, acid and alkali resistance, long service life, and the forging flange does not have Sand holes and pores on the surface. While cast steel flanges usually have sand holes and pores and rough appearance, but the price is cheaper than the forging flange. General forging flange thickness is thicker than cast steel flange, but cast steel flange also has thick type. Customer usually does not know how to buy, we also talk about it in this article. General pipe cast steel flanges are generally able to meet pipe demand, the price is more acceptable. Economical flexible rubber joints consist of cast steel flanges and good rubber joints.

The so-called non-standard flange in the market is that the center distance is national standard, the inner diameter is large, the outer diameter is small, so the cost is low and the price is cheap. If this kind of flange is connected with the flexible rubber joint, the seal face will appear only half way. Some have no concentric installation in the course of installation, the sealing face is only pressed to 1/3, it will burst from the sealing face under high pressure. Why choose the national standard butterfly valve special flange? The inner diameter of soft seal butterfly valve are all rubber and sealing surface is also rubber. If the sealing surface with a large diameter flange is too small to be completely sealed, resulting in the leakage of the butterfly valve, so the rubber joint is the same as the butterfly valve, which needs to be selected with the special flange of butterfly valve. Then it can effectively ensure the safe use of flexible rubber joint, good sealing, long lifetime, and no water leakage phenomenon.

Gong Yixinli is a large rubber joint manufacturer, wholeheartedly providing users with high quality products and good service. In order to improve the stability of flexible rubber joints, the risk of flexible rubber joints being pulled off is greatly reduced by installing limit devices in some special installation environments.
