Stainless Steel Flanges Their Types and Applications


Stainless steel flanges play a crucial role in various industrial applications, providing a secure and leak-free connection between pipes, valves, and equipment. In this article, we will explore the different types of stainless steel flanges and their applications, shedding light on their unique characteristics and benefits.

Flanges with Weld Necks

Flanges with weld necks are one of the most common types of stainless steel flanges. They have a long, tapered neck that is welded to the pipe, ensuring a strong and durable connection. The key advantages of weld neck flanges include their high strength, resistance to deformation, and suitability for high-pressure applications. They are commonly used in industries like oil and gas, petrochemical, and power generation.

Slip-On Flanges

Slip-on flanges are easy to install and are slipped over the pipe end before being welded in place. They are cost-effective and ideal for applications where frequent disassembly is not required. Slip-on flanges are commonly used in low-pressure systems, such as water supply, heating, and ventilation systems.

Blind Flanges

Blind flanges are solid discs used to block off the end of a pipe or a vessel. They are often employed to close off unused pipelines or for pressure testing. Blind flanges provide a reliable seal and are crucial in industries where containment and isolation of fluids are essential, such as chemical processing and pharmaceuticals.

Threaded Flanges

Threaded flanges have internal threads that allow them to be screwed onto the pipe or another fitting. They are popular in applications with smaller pipe sizes and low-pressure requirements, such as plumbing systems and instrumentation. Threaded flanges offer ease of assembly and disassembly.

Ring Type Joint Flanges

Ring type joint (RTJ) flanges are designed for high-pressure and high-temperature applications, such as those found in the oil and gas industry. They feature a metal ring gasket that ensures a tight seal even under extreme conditions. RTJ flanges are commonly used in wellheads, pipelines, and offshore platforms.

Orifice Flanges

Orifice flanges are specifically designed for flow measurement and control. They have a small, concentric hole that accommodates an orifice plate or flow meter. These flanges are used in industries like chemical processing, where precise measurement of fluid flow is critical for process control and optimization.


Stainless steel flanges come in various types, each tailored to specific applications and requirements. Whether you need high-pressure resistance, leak-proof sealing, or precise flow control, there is a stainless steel flange suitable for your needs. Understanding the different types of flanges and their applications is essential for selecting the right one for your project, ensuring safety, reliability, and efficiency in your industrial processes.
