SAE Socket Weld Elbow Flanges are one of the popular type of SAE socket wled flanges. The elbow is usually 90°. So they are know as SAE 90° Flanges as well.
Materials:
- Carbon steel SAE 90° Flanges: C45, C20, CQ235, or on requests.
- Stainless steel SAE 90° Flanges: 304, 316, 316L, 316Ti or equivalent EN/DIN stainless steel grades 1.4301, 1.4401, 1.4404, 1.4571, used for connecting stainless steel hydraulic tubing.
Main series & Size Range:
SAE 90° Flanges come in two varieties, and here below is the size range of each variety:
- for 3000 PSI Standard Pressure Series: 1/2″ (DN13) to 3″
- for 6000 PSI High Pressure Series: 1/2″ (DN13) to 2″ (DN51)
3000 PSI series also is known as code 61 SAE flanges, while 6000 psi high pressure series is known as code 62 SAE flanges.
Surface:
Carbon steel socket weld elbow flanges are usually supplied in surface condition as below:
- Zinc coated (white)
- Galvanized zinc (yellow)
- Phosphated (black)
- Nickle plated
- Blank + oiled
- Untreated oxidation
- Blank
Working Pressure:
- 3000 psi standard series: 35 bar to 350 bar
- 6000 psi high pressure series: up to 420 bar.
The working pressure is also determined by the sizes of the SAE socket weld elbow flange, and the grade (10.9 or 8.8) of the bolts used.
