Application characteristics of slip on flange
The slip on flange not only saves space and weight, but also ensures that the joint will not leak and has good sealing performance. The compact flange size is reduced by reducing the seal diameter, which will reduce the seal face section. Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing face matches the sealing face. In this way, only a small amount of pressure is required to compress the sealing surface. With the decrease of the required pressure, the size and quantity of the bolts can be reduced correspondingly, so a new product with small volume and light weight (70% – 80% less than the weight of the traditional flange) is finally designed. Therefore, the slip on flange is a relatively high-quality flange product, which reduces the quality and space, and plays an important role in industrial use.
However, the main design disadvantage of slip on flange is that it cannot guarantee no leakage. This is the deficiency of its design: the connection is dynamic, and such as thermal expansion and fluctuating periodic load will cause the movement between flange faces, affect the function of the flange, thus damage the integrity of the flange, and eventually lead to leakage.
It is impossible for any product to be free of defects, just try to control the defects of the product to the minimum, so the company tries to improve the performance of the product when producing the slip on flange and make it play the most important role.
