Types of Stainless Steel Flanges

There are several types of stainless steel flanges, each designed for specific applications. The most common include:

• Slip-On Flanges: These flanges slip over the pipe and are then welded both inside and outside, providing a strong, secure connection.
• Weld Neck Flanges: This type features a long neck that allows for a gradual transition between the flange and the pipe, reducing stress at the joint.
• Blind Flanges: Used to close the end of a piping system; they are solid disks with no center opening.
• Threaded Flanges: These are useful in high-pressure applications, enabling the flanges to be screwed onto the pipe rather than welded.
• Socket Weld Flanges: Similar to slip-on flanges but with a socket for the pipe end, providing greater strength in high-pressure applications.

Materials and Grades of Stainless Steel

Stainless steel flanges are commonly made from various grades of stainless steel, which offer different properties and benefits. The most widely used grades include:

• 304 Stainless Steel: This is one of the most versatile and commonly used grades, known for its excellent corrosion resistance and good formability.
• 316 Stainless Steel: This grade provides improved corrosion resistance, especially in marine environments or those exposed to chlorides, making it ideal for chemical processing and seawater applications.
• 410 Stainless Steel: Known for its high strength and moderate corrosion resistance, 410 is frequently used for flanges requiring wear resistance.

Applications of Stainless Steel Flanges

Stainless steel flanges are used across various industries, including:
