How to order SAE Split Flange
SAE Split Flanges are made following the SAE J518C specifications. The split flange is applied in high-pressure hydraulic applications due to its ability to withstand high pressure, shock, and vibration. The split flange is available in two series, 3000 series, and 6000 series.
​
Furthermore, the flange is also referred to as Code 61 Split Flange and Code 62 SAE Split Flange. They are available in different sizes. For the 3000 series, their sizes range between 1/2” to 5” (DN 15 to DN 125), and for the 6000 series, the sizes are 1/2” to 3” (DN15 to DN 80). SAE Split Flanges are made majorly of Stainless steel SS316 and Carbon Steel ST52.3.
​
To order a split flange, follow the steps below.
Step 1: Determine the type of SAE Split Flange.
SAE Split Flanges are available in two types: the group Uncut Split Flange and the double Uncut Split Flange. The first step is to determine which is best for your application.
​
-
Cut SAE Split Flange: Both Cut SAE Split Flanges are related after assembly. The only distinction can be noticed before the SAE Split Flanges are coupled. The major distinction is that the complete set SAE Split Flange installation has two sets of double Split Flanges and double adapters against the single components for the group Uncut Split Flange. Also, another difference is in the dissembling process. For the cut SAE Split Flange, the process is easy, and the system can be in operation during dissembling.
​
-
Uncut SAE Split Flange: The Uncut SAE Split Flange is the standard type of split flange. The flange comes with an O-ring, an Uncut split flange, washer, bolt, and a flange adapter. The o-ring is a seal placed between the flange halves to provide a tight and secure connection. For further secured connection, there are bolts to be fastened to the split flange head. The spring washers in the package are for equal distribution of load during operation and to prevent friction between the flange and the bolts. The bolts are also fastened to the flange adapter and the Uncut Split Flange.
​
-
Uncut SAE Split Flange (MM bolt thread): There are four bolt threads in the Uncut SAE Split flange body. It strengthens the assembly process as no additional component is required such as hexagon nut.
​
One important thing to know about group uncut split flange is that the disassembly time can tarry. The whole operation has to be stopped, and the complete disassembly of all the connected devices before the group uncut split flange is removed.
Step 2: Determine the SAE Split Flange material
Stainless Steel SS316: It is suitable to use in seawater installation and known as great reliable corrosion resistance as it has materials of molybdenum, nickel, and chromium.
​
Carbon Steel ST52.3: It is suitable in common ground applications such as chemical plants, cranes and mining industry, and chemical plants as it known as good cold-forming material.
Step 3: Determine the SAE Split Flange working pressure for your application.
SAE Split Flanges come in two series. And since they are designed for different working pressure ranges, they are not interchangeable. There are different ways to determine whether a Code 61 or Code 62 is applicable for you.
-
Measuring the dash size.
-
Measuring the size of the connector or piping
-
Measuring the spacing between the bolt holes, pitch circle diameter
Split Flanges are designed in two pressure series, Code 61 and Code 62.
​
-
Code 61 is called the medium-pressure series. They are rated at a peak working pressure of 3000 PSI.
-
Code 62 is called the high-pressure series. There are different sizes of the split flange based on these pressures. They are rated to have a working pressure of 6000 PSI.
Step 4: Determine the SAE Split Flange piping size
The SAE split flange is available in sizes from 3/8” to 5”. The pipe mm sizes are available from 17.1mm to 114.3mm. The SAE Split Flange comes with outer diameter tolerance that allows bevel end piping welding installation.
Step 5: Determine the SAE Split Flange quantity
Confirm the SAE Split Flange quantity required before proceeding to order confirmation.
