A stainless steel flange is a type of pipe fitting that is used to connect pipes, valves, pumps, and other equipment in a piping system. It provides a way to create a secure and leak-resistant joint between different components. Stainless steel flanges are widely used in various industries due to their corrosion resistance, durability, and ability to withstand high-pressure and high-temperature conditions.

Here are the key features and points to know about stainless steel flanges:

1. Function:

   • Connection: Stainless steel flanges allow for the connection of pipes, valves, and other equipment by bolting them together.

   • Access: Flanges provide access to the piping system for inspection, maintenance, or cleaning.

2. Types of Flanges:

   • Weld Neck Flange: This type of flange has a long neck that is welded to the pipe, providing reinforcement and minimizing stress concentration. It's suitable for high-pressure and high-temperature applications.

   • Slip-On Flange: A slip-on flange slips over the pipe and is then welded in place. It's easy to install and is commonly used for lower-pressure applications.

   • Socket Weld Flange: This flange has a socket for the pipe to fit into and is then welded around the base of the socket. It's suitable for smaller pipes and high-pressure applications.

   • Threaded Flange: A threaded flange has internal threads and can be screwed onto the pipe. It's used for low-pressure applications.

   • Blind Flange: A blind flange is used to close the end of a pipe or nozzle. It's often used for capping off piping systems or creating access points.

   • Lap Joint Flange: This flange is used with a lap joint stub end to create a joint that allows for easy assembly and disassembly without disturbing the main flange.

   • Orifice Flange: Designed for metering systems, it has a precision-drilled hole to measure the flow of liquids or gases.

3. Materials and Grades:

   • Stainless Steel Grades: Stainless steel flanges are typically made from stainless steel grades such as 304 (A2) and 316 (A4) due to their corrosion resistance properties.

4. Applications:

   • Oil and Gas: Used in pipelines for transporting oil, gas, and other fluids.
