Product Name：Stainless Lap Joint Flange
The flange is a part that connects the pipe to the pipe and is connected to the pipe end. There are holes in the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange threaded connection (wire connection) flange and welded flange
1. The flange cover is easy to use and can bear large pressure.
2. Flange connection is widely used in industrial pipeline. In the home, the diameter of the pipe is small, and it is low pressure, and the flange connection is invisible. If in a boiler room or production site, there are flange connected pipes and equipment everywhere.
3. The cover plate of flange is mainly used for equipment test, pressure test, etc.

How does the non-standard flange realize the switch and flow control
Non-standard flanges are piping systems used to implement switches and flow control components. They have been widely used in many fields of petroleum, chemical, metallurgy, hydropower and other industries. It is well known that the non-standard flange technology, the sealing form is a closed structure, and the sealing material is rubber and polytetrafluoroethylene. However, due to its structural characteristics, it can be used in environments such as high temperature, high pressure, corrosion resistance, and wear resistance.
However, there are some problems in the use of non-standard flanges:
1. Since the soft and hard stack rings are fixed on the valve plate, the valve plate is often opened to form a sealing surface erosion and the metal soft seal directly affects the sealing performance.
2. The restriction valve that does not meet the structural size through the structural conditions, because the overall structure of the valve plate is too thick and the flow resistance is too large.
3. Due to the principle of triple eccentric structure and the torque transmitted between the sealing surface of the valve seat, the valve plate is pressed on the valve seat. In a positive flow state, the higher the pressure, the tighter the medium seals, and the valve plate and the valve will increase when the pressure of the reverse flow medium and medium If the positive pressure between the seats is less than the media pressure, the seal will begin to leak. You must pay attention to this.
