SAE blind flange, also known as SAE flange cover and SAE flange blind plate, is divided into grooved and non grooved. It is usually used at the beginning or end of the hydraulic system.
Slotted SAE flange blind is sealed by O-ring
The four connecting holes of the slotted SAE flange blind plate are threaded and sealed with bolts, gaskets, etc
The SAE Blind Flange can withstand pressure up to 6000 PSI which is equivalent to 420 bars.It is applicable in larger piping line where 3 to 5 inches’ pipe is required.The workable pressure of SAE Blind Flange is 500 PSI or 34 bars for piping size more than 3 inch.While the minimum pressure for flange size in between 1/2 inch to 1 inch is 345 bars or 5000 PSI.
The pressure of the forged flange body allows the flange to install in high-temperature environment and achieve corrosion resistance.
The simplicity of the SAE Blind Flange standard design is proven to be better than the traditional threaded port installation methods. There is a much lower tightening torque value required when it comes to installation with a piping line. They allow easy assembly in tight spaces and create a leak free connection. It is critical and important with pipeline applications, especially for high pressure systems.
