Slip-on flange, a kind of discoid parts, is the most common goods in the pipeline engineering. Flanges are all operated in pairs. In pipeline project, flange is mainly used for pipe connection. The pipes which are in need of connection are installed a piece of flange accordingly. Low pressure pipes can manipulate the silk flanges. More than 4 kg pressure pipes can operate welding flanges. Then, add sealed point between two slices of butt welded flange plates and fasten them by bolt. The flange with pressure differences has controversial thickness and controversial manipulation of bolt.

Slip-on flange saves space and reduces weight. More importantly it ensures that the negotiating position will not leak, having the function of exquisite sealing. That compact flange size is reduced is because the diameter of seals is reduced. It will reduce the thickness of the sealing surface cross section. Second, flange gasket has been acted in sealing ring’s place so as to ensure that the sealing surface vertical chamber. Thus, considering that the rigorous sealing cover only needs small pressure and the required pressure is also reduced, the size of the bolt and the required number can response to be reduced. So, the final plan launches new products with a small volume and light weight (70% ~ 80% reduction in weight than traditional flange). It is a kind of product with powerful and high-quality flat welding flange and reduces the weight of quality and space.

The main drawback of slip-on flange is that it does not guarantee that there is no leakage. Thermal expansion and uncertain heave cyclic load lead to the movement of flange surface, influencing the effect of the flange. This makes the integrity of the flange be damaged, and eventually results in leakage. No products generally have no defects. Companies even have improved the function of the products, however, they can not guarantee that it is perfect without any defects.
