The materials used to fabricate SAE flanges are steel and stainless steel. Threaded SAE Flange. Clients who viewed this product also viewed:. Stainless Steel Pipes. Pipe Clamps. For Code 62 series, the maximum working pressure are Bar. However, the pressure rating of SAE flanges and connected equipment combination might vary from each other. For example: if a pipe connected to the flange has a lower maximum working pressure, it will result in an overall lower working pressure of the system.
Therefore in a system, the item with the lowest pressure will be the maximum working pressure of the system. Flanges with oring are has an advantage of prevent leakage as all metal-to-metal flanges are more prone to leakage.
The configurations of SAE flanges are flat side, oring side or complete set. A complete set of SAE flanges are combination of flat side and oring side where it forms a seal between the flat surface and oring held in a recessed circular groove in the other half.
By tightening the bolts, it draws flat side and oring side together and compresses the oring. Because of the high pressure, it is important to note that every hydraulic or pneumatic system requires some form of fitting installation for completion. Do watch our youtube video and our instructions below carefully! STEP 1. Ensure the sealed surface are free from scratches and contamination. Lubricate with system fluid or any compatible lubricant on the surface of O-ring portion.
STEP 2. Position the flange. Place the washer on cap screws and bolt through the bolt holes. STEP 3. Tighten the cap screws by hand. Torque the cap screws gradually in diagonal sequence till the appropriate torque level based on below torque table. STEP 4. Tighten the cap screws according to the below torque table.

SAE Flanges are also known as code 61 flanges or code 62 flanges. These 4 bolt flange connections are proven, leak-free connections, especially suitable for large size high pressure applications. Because of the o-ring seal design, SAE flanges provide connections with reasonable assemble torque range. SAE Flanges are made of ferrous material. The materials usually used are carbon steel ST The most commonly used are socket welding type and butt welding type. The minimum o-rings seals quality is as per grade N of ISO
