Stainless Steel Weld Neck Flange Supplier
A Stainless Steel Weld Neck Flange is a type of flange used in piping and plumbing systems to connect pipes, valves, and other equipment. It is designed to be welded to the neck of a pipe, creating a strong and leak-proof connection. Here are some key details about stainless steel weld neck flanges, including types, grades, features, and applications:
Types:
Standard Weld Neck Flange: This is the most common type of weld neck flange, featuring a circular design with a tapered hub and a neck that connects to the pipe. It is suitable for most applications.
Long Weld Neck Flange: This type has a longer neck, providing additional reinforcement and support for high-pressure and high-temperature applications.
Swivel Ring Flange: These flanges have a rotating ring that allows for easy alignment during welding, making them useful in situations where alignment is critical.
Weld Neck Raised Face Flanges: These Flanges are one of the most commonly used flanges in the piping industry. They are easy to recognize with their long tapered hub that is matched to the wall thickness (bore) of the pipe.
Grades: SS Weld Neck Flanges are available in various grades, with the most common ones being from the 300 series, such as Stainless Steel 304 Weld Neck Flanges and Stainless Steel 316 Weld Neck Flanges. The grade you choose depends on the specific requirements of your application. For example, 304 stainless steel is often used in general applications, while 316 stainless steel offers enhanced corrosion resistance and is suitable for marine or chemical industry applications.
