There are different types such as the A182 F304 SORF Flange which is a slip on raised face flange. The slip on flanges are suitable to be used with seamless pipes to make precise connection locations. The raised face of the flanges provides extra surface for connection either by welding or b bolting.
A stainless steel slip-on raised face (SORF) flange is a circular disc with a raised face that attaches two pieces of pipe together with bolts:
| Features |
Material |
Stainless steel, which is durable, strong, and resistant to corrosion |
Design |
A slip-on flange that slides over the pipe and is welded in place |
Raised face |
Provides a sealing surface for gaskets and ensures a tight connection |
Hub |
Extends beyond the pipe's outer diameter and provides additional strength and stability |
Applications |
Used in industries such as oil and gas, petrochemical, chemical processing, power generation, and water treatment |
Common grades of stainless steel used for SORF flanges include 304, 316, and 316L. 316 stainless steel contains molybdenum, which improves its resistance to corrosion, especially in environments with more chloride or saline.
