Where are flanges used?
Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a “blind flange”. Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods.
What are the different types of stainless steel flanges?
8 Types of Stainless Steel Flanges to Choose From
- Weld Neck Flanges. Their distinct feature is their protruding neck.
- Threaded Flanges. They are only used for special applications.
- Slip-on Flanges.
- Lap Joint Flanges.
- Socket Weld Flanges.
- Ring-Type Joint Flanges.
- Orifice Flanges.
- Blind Pipe Flanges.
How are flanges classified?
The key types of flanges are the welding neck, long welding neck, slip-on, socket weld, lap joint, threaded and blind flanges. In addition to these standard flanges, some special ones exist, called Weldoflange/Nipoflange and Elboflange, swivel flange, expander/reducer flange, and orifice flanges.
What is stainless steel flange?

What is ASTM A182?
ASTM 182 is a standard specification. This covers forged or rolled alloy and stainless steel pipe components to be used in pressure systems. Included are several grades of low-alloy steel, including martensitic, austenitic and ferritic-austenitic.
What is flange material?
The most common materials for pipe flange manufacturing are carbon steel, high yield carbon steel, alloy steel, stainless steel, duplex and super duplex, and various nickel alloy grades such as Inconel, Incoloy, Hastelloy, and Monel.
