Threaded Flange

It seems like you are discussing different types of flange sealing surfaces and their suitability for different pressure conditions.The first type mentioned is the plane flange, also known as a flat flange. This type of flange has a flat sealing surface, which results in a large gasket contact area. However, during pre-tightening, the gasket can easily extend or move to both sides, leading to poor sealing. Therefore, plane flanges are typically suitable for low-pressure occasions.The second type mentioned is the concave and convex flange, also known as a groove flange. This flange has a sealing surface with two concentric grooves and a triangular interface, commonly referred to as the waterline. This design aims to increase contact friction and improve sealing. However, it is important to note that this design requires the use of a soft gasket. Groove flanges are typically considered suitable for high-pressure occasions due to their improved sealing properties.Lastly, the tenon surface flange is mentioned as the third type of flange sealing surface. Unfortunately, no further information is provided about this type of flange.
