Slip-on (SO) flanges are a type of flange that has a flat face on the sealing surface and are typically used in low-pressure applications. They are called “slip-on” because they can be easily slipped onto the end of a pipe or fitting and then welded in place. They also have a bored-out inner diameter that matches the pipe’s outer diameter, allowing for a smooth flow of fluids or gases.

This article will explore the fundamentals of these flanges, including their working principles, advantages, and various types available.

HOW SLIP-ON FLANGES WORK
SO flanges provide a secure and leak-resistant connection between pipes or fittings in a piping system. The process begins by slipping the flange onto the end of the line, ensuring the flange’s inner diameter matches the pipe’s outer diameter. This allows for a smooth transition and maintains a consistent flow path.

Once the component is positioned correctly, it is then welded to the pipe. The welding creates a strong bond between the flange and the line, ensuring a reliable and durable connection. Moreover, the flange’s flat face provides a sealing surface easily aligned with gaskets or rings to prevent leakage.

ADVANTAGES OF UTILIZING SLIP-ON FLANGES
SO flanges offer the following advantages, making them a popular choice in numerous piping systems across different industries:

EASE OF INSTALLATION
The slip-on design enables effortless mounting to the end of a pipe or fitting without intricate alignment procedures. This saves time and effort during installation, especially when many flanges are involved. They can also be adjusted slightly after sliding onto the pipe, simplifying proper alignment between pipes or fittings.
