<\/div>

Stainless Steel Flanges<\/strong> are important parts used in many piping systems. They help connect pipes, valves, pumps, and other equipment to form a strong and leak-proof system. These flanges also make it easier to repair or inspect the pipes when needed. There are different types and grades of stainless steel flanges<\/strong><\/a>, each made for specific uses.<\/p>\n

Let\u2019s understand the different types of stainless steel flanges<\/strong> and their common materials.<\/p>\n

Types of Stainless Steel Flanges<\/h2>\n

1. Weld Neck Flange<\/h4>\n

This flange has a long neck that is welded to the pipe. It gives strong support and handles high pressure and temperature well. Weld neck flanges are commonly used in critical systems.<\/p>\n

2. Slip-On Flange<\/h4>\n

A slip-on flange is easy to install. It slides over the pipe and is welded from both inside and outside. These flanges are perfect for low-pressure systems.<\/p>\n

3. Blind Flange<\/h4>\n

Blind flanges are used to close the end of a pipe or valve. They are useful when you need to block off a section of pipe for inspection or repair.<\/p>\n

4. Threaded Flange<\/h4>\n

Threaded flanges have internal threads that match the external threads of a pipe. These flanges do not need welding and are used in low-pressure and non-critical systems.<\/p>\n

5. Socket Weld Flange<\/h4>\n

This type has a socket where the pipe is inserted and then welded. It is used for small pipes in high-pressure systems. It also gives a strong and smooth connection.<\/p>\n

6. Lap Joint Flange<\/h4>\n

Lap joint flanges are used with a stub end. They are useful for systems that need to be taken apart often. These flanges help in easy alignment and fitting.<\/p>\n

7. Ring-Type Joint (RTJ) Flange<\/h4>\n

RTJ flanges are used in high-pressure and high-temperature systems. They have a special groove for a metal ring gasket, which gives a strong seal.<\/p>\n

8. Orifice Flange<\/h4>\n

Orifice flanges are used to measure the flow of liquids or gases in a pipeline. They come with holes to connect instruments for flow measurement.<\/p>\n

Common Grades of Stainless Steel Flanges<\/h3>\n

Stainless steel flanges<\/strong> are made in different grades based on where they are used. Here are some common ones:<\/p>\n
