Threaded Flange	Internal threads for connection; no welding needed	Low-pressure systems, gas pipelines	Pros: Easy installation; Cons: Not suitable for high-pressure applications.

Weld Neck Flange

Weld neck flanges are characterized by their long neck, which allows for welding directly to the pipe. This feature provides enhanced strength and is ideal for applications subjected to high stress and pressure, such as in oil and gas or chemical processing industries. When purchasing, buyers should consider the installation costs associated with welding and ensure compatibility with existing piping systems to maximize performance.

Slip-On Flange

Slip-on flanges are designed to slide over the pipe, making them easy to align and install. These flanges are commonly used in general piping applications, including water systems. They offer a cost-effective solution, but buyers should be aware that they may not provide the same strength as weld neck flanges, especially in high-pressure environments. Proper installation is crucial to ensure a reliable seal.

Socket Weld Flange

Socket weld flanges feature a socket into which the pipe is inserted, making them suitable for high-pressure applications. Commonly found in power plants and refineries, these flanges provide a stronger connection than slip-on flanges. However, buyers should consider the need for precise fitting and the welding process, which can increase installation time and costs. Ensuring the right specifications for pressure and temperature ratings is essential.

Blind Flange

Blind flanges are solid flanges without any openings, primarily used to seal off the ends of piping systems. They are particularly useful in maintenance shutdowns and pressure testing scenarios. While their simple design makes them easy to use, buyers should note that blind flanges are not reusable once installed and have limited applications. Proper selection is crucial for ensuring they meet the operational requirements of the system.

Threaded Flange

Threaded flanges have internal threads that allow for easy connection without welding, making them ideal for low-pressure systems such as gas pipelines. Their straightforward installation process is a significant advantage for many buyers. However, it is essential to consider that threaded flanges are not suitable for high-pressure applications, as the threads can strip under excessive load. Buyers should evaluate the specific conditions of their application to ensure a suitable choice.
