Stainless Steel Sorf Flanges with Hub Manufacturer and Supplier In India
Stainless steel Slip-On Raised Face (SORF) flanges with a hub are a type of pipe flange used in piping systems for connecting pipes or machinery. These flanges have a raised face and a hub, which is a swollen portion on the flange that fits over the pipe's end. Stainless steel SORF flanges with a hub, also known as Slip-On Raised Face flanges with hub, are commonly made from stainless steel materials known for their corrosion resistance and durability. These flanges are described by their raised face, which provides a sealing surface for gaskets, and a hub, which fits over the pipe's end. They are usually connected to the pipe by welding the hub to the pipe. The applications are general piping systems, water treatment plants, chemical and petrochemical industries, power generation and many more.

Types of Stainless Steel Sorf Flanges with Hub
We, at Naysha Steel, offer various types of stainless steel SORF (Slip-On Raised Face) flanges with hub.
Here are a few common types:
- Standard SORF Flanges with Hub: Our traditional stainless steel slip-on flanges with a raised
face and a hub, allowing easy alignment and welding to the pipe.
- Weld Neck SORF Flanges with Hub: Our SORF flanges have a longer neck that extends beyond the
pipe, providing additional strength and support. These flanges are ideal for high-pressure and
high-temperature applications, offering great strength and toughness.
- Socket Weld SORF Flanges with Hub: Our flanges have a socket weld connection instead of
a butt weld. They are designed for smaller pipe sizes and provide a more compact and safe
joint, suitable for applications where there is limited space.
- Threaded SORF Flanges with Hub: Our flanges have internal threads to match the pipe's
external threads, allowing for easy setup without welding.
- Lap Joint SORF Flanges with Hub: Our stainless steel SORF flanges have a flat face and a hub, and they are
typically used associated with a stub end.
