Common Types of Stainless Steel Flange

Weld Neck Flange: This type is used in high-pressure systems. It has a protruding neck and an end face welded to the pipe.
Slip-On Flange: With this type, the pipe is inserted into the flange and then welded, making it convenient for installation.
Blind Flange: This type is used to block the end of the pipe without any holes.
Threaded Flange: This type allows for internal thread and external thread pipe connection without requiring any welding.
Socket Weld Flange: With this type, the pipe is inserted into the socket of the flange and then welded. It is suitable for small-diameter high-pressure pipes.

Advantages of Stainless Steel Flanges

Corrosion Resistance and High Strength

Stainless steel flanges offer excellent corrosion resistance and high strength, making them ideal for resisting various chemical media and operating in high-temperature and high-pressure environments. This ensures the stability and safety of pipe connections.

Long Service Life

Due to their outstanding corrosion resistance and strength, stainless steel flanges typically have a longer service life, reducing the need for frequent replacements and lowering maintenance costs.

Hygiene and Aesthetic Appearance

Stainless steel flanges have good hygienic properties, ensuring that they do not contaminate the media, making them suitable for the food, beverage, and pharmaceutical industries. Additionally, their smooth surface and attractive appearance maintain a good look even in exposed applications.

Weldability and Versatility

Stainless steel flanges have excellent weldability, allowing for high-quality welding with other pipes or equipment. They also come in a wide range of specifications, making them suitable for various industrial needs.

FAQ

How should stainless steel flanges be maintained?

Regular inspection and cleaning are recommended to maintain the performance and appearance of stainless steel flanges. Use mild cleaning agents and avoid abrasive materials that can scratch the surface. For flanges in corrosive environments, consider applying a protective coating or using passivation to enhance corrosion resistance.

How do I select the right stainless steel flange for my application?

When selecting a stainless steel flange, consider the operating environment to choose a material grade with adequate corrosion resistance. Ensure the flange meets the necessary pressure and temperature ratings, is the correct size, and is compatible with your pipes and fittings. Additionally, verify that the flange complies with industry standards such as ASTM, ASME, or DIN.
