What is the design principle of Hydraulic SAE Flanges?

1. Flange connection structure
The design of Hydraulic SAE Flanges first needs to consider its connection structure. The connection structure of hydraulic flanges generally consists of two main parts: a fixed flange installed on the pipe or equipment and a matching connecting flange. The two flanges are fixed together by bolts and nuts to form a strong connection. The contact surface of the flange is usually equipped with seals, such as O-rings or gaskets, to prevent fluid leakage.
The flange connection of Hydraulic SAE Flanges needs to be tightly and evenly compressed to avoid leakage caused by improper connection in high-pressure systems. The standard SAE flange size and the spacing design of the connection holes make the flange compatible with other standardized components and enable quick installation and removal.

2. Sealing performance
Sealing performance is the core element in the design of Hydraulic SAE Flanges. Hydraulic systems are usually in a high-pressure and high-temperature working environment. The sealing function of the flange directly determines the stability and safety of the system. In order to prevent fluid leakage, Hydraulic SAE Flanges will be equipped with special sealing rings on the contact surface. Common sealing materials include rubber, polytetrafluoroethylene (PTFE), etc., which can still maintain good sealing performance under high pressure and high temperature.
The sealing design must be able to be used for a long time under high pressure conditions without damage or leakage. The sealing ring usually achieves the sealing effect through the compression force of the flange. Therefore, it is necessary to ensure that the pressure of the flange connection is high enough to ensure the sealing performance of the sealing ring during design.

3. Selection of high-strength materials
Hydraulic SAE Flanges need to withstand extremely high pressure and temperature in hydraulic systems, so the selection of materials is crucial. Generally, hydraulic flanges use high-strength metal materials such as stainless steel, carbon steel or alloy steel. These materials have strong pressure resistance, corrosion resistance and high temperature resistance, and can maintain stable performance in harsh working environments.
Stainless steel flanges are widely used in the transportation of corrosive liquids, while carbon steel flanges are more suitable for conventional hydraulic systems. For special systems working under high pressure or extreme environments, designers may choose to use alloy steel or other special materials to ensure that the flange can withstand extremely high loads and harsh conditions.

4. Bolt and fastener selection
Bolts and fasteners also play an important role in the design of Hydraulic SAE Flanges. The choice of bolts determines the tightness of the flange connection. They need to provide sufficient tightening force to prevent the flange connection from loosening under the action of high-pressure liquid. In hydraulic systems, flange connections are usually connected by several bolts to distribute the pressure to ensure the uniformity of the connection.
To ensure long-term reliability, bolts and nuts are usually made of high-strength alloy steel and anti-corrosion coatings are used to improve corrosion resistance. In addition, the size and number of bolts must be precisely designed according to the pressure level of the system and the size of the flange.

5. Pressure adaptability and strength design
The pressure in hydraulic systems is usually high, so the flange design must be able to withstand the working pressure without cracking or deformation. The wall thickness, size and shape of Hydraulic SAE Flanges are closely related to the pressure level. The design of the flange needs to ensure that it can maintain sufficient strength under high-pressure environment to avoid failure during operation.
The pressure adaptability design of the flange is usually based on SAE standards to ensure that it can be used in high-pressure environments for a long time without leakage or damage. Pressure fluctuations and temperature changes in hydraulic systems can also affect the sealing effect of flanges. The impact of these factors on the long-term stability of flanges needs to be considered during design.

6. Dimensions and standardized design
Hydraulic SAE Flanges are usually designed and produced according to SAE standards to ensure that flanges are compatible with other hydraulic components. The standardized design allows flanges to be widely used in different hydraulic systems, making it easier for users to choose according to specific needs. Standardization also makes the production, maintenance and replacement of flanges more convenient.
The size and standardized design of flanges also make it easy to expand and modify hydraulic systems. If some parts of the system need to be replaced or upgraded, standardized flanges can reduce adaptation problems and increase system flexibility.
