SAE Split Flange
Split Flanges are designed following the SAE J518 standards. Split flanges are identified as one of the most popular flange types and are mostly used due to their ability to withstand high pressure. Alternatively, split flanges are referred to as Code 61 Split Flanges and Code 62 Split Flanges. Split flanges are available in two major pressure series, 3000 PSI and 6000 PSI. They are made from stainless steel SS316 and SS316L, and Carbon Steel ST52.3. The sizes of the split flanges range between 1/2 inch to 5 inches and 1/2 inch to 3 inches (based on the pressure level).
1. What are Flanges ?
Flanges are special connecting tools for hydraulic systems and applications. They are used to join one or more pipes, hoses, etc together and are built to ensure the smooth passage of the liquid process. More importantly, flanges serve and provide a secure and leak-free connection for hydraulic systems, flanges are available in various types, shapes, and pressure ratings. The particular model is used based on the application intended.
Split flanges are specially designed to solve a major problem in connection. Split flanges, otherwise known as Code 61 Split Flange and Code 62 Split flange have the capability to provide a connection in a tight area without any availability of leakages during operations. They are designed following the SAE J518 standards and are built for high-pressure applications. The pressure ratings of the flange are 3000 PSI or 6000 PSI and they are available in a variety of sizes based on the pressure. The general pressure rating stands between 1/2 inch and 5 inches. The flange comes in a cut and uncut type. One of the distinct qualities of a split flange is the ability to withstand high-pressure, vibration, shock, and other effects that can damage the hydraulic application.
2. What are Split Flanges made of?
Split Flanges are generally made of two materials, Carbon Steel ST52.3, and Stainless steel SS316. Carbon steel is one of the most common materials used in the production of industrial tools. Carbon steel mainly comprises steel and the grade is S355. The carbon level of this material ranges from 0.05% to 0.22%. The carbon material increased gives the material a high tensile power and hardness.
​
Stainless steel SS316, SS316L, etc are stainless steel variants that have more quantity of one element over others. For example, SS316L has a high content of molybdenum. The basic element in the stainless steel material is a carbon (C), Nitrogen (N), Sulfur (S), Silicon (Si), Selenium, Chromium. Of these elements, chromium has the highest percentage (11%).
​
Although these materials are the most common in the production of split flanges, there is an opportunity to order specialized materials to be available.
3. What is the working pressure of a Split Flange?
The split flange is designed in two standard pressures. These are 3000 PSI and 6000 PSI. The 3000 PSI is a standard pressure that can withstand the working pressure between 35 and 350 bars. This is considered low compared to the 6000 PSI that can accommodate wiring pressure equal to or above 400 bars. Before selecting the split flange, you have to know that the working pressure of this flange is determined by the bolts model and flange size.
4. What are the maintenance processes for a Split Flange?
Before the destruction of a split flange, some signs could be detected when there is a need for a part change or general maintenance of the system. Please note the following steps to elongate the lifespan of the split flange in an installation:
​
Scratches: scratches on the surface of the split flange should be avoided, however, you must periodically check for any. When there is a scratch, it could lead to leakage of process fluid or the destruction of the flange. However, when this is noticed early, it can be avoided.
​
Also, avoid dragging the flange surface on the floor as this could also cause scratches. But, some flanges are bought with scratches on them, hence, check the surface area of the split flange thoroughly before installing. This will help avoid unforeseen circumstances.
​
The split flange can be used with a flange head adapter. Follow the steps below to assemble the flange:
Step 1
Ensure the flange surface is free from dirt and other contaminants.
Step 2
Generously fabricate the pouring
Step 3
Insert the flange head into the split flange body. Place both flange head and split flange in the right positions
Step 4
Insert lock washers on the bolts. Then, insert the bolts in the holes.
Step 5
Carefully tighten the bolts using your hand. Ensure you follow the right torque values.
