Product Introduction
The Slip On Flange (SO) is easy to install. It slides over the pipe and is welded for strength. We offer SS Slip On Flange and ANSI Slip On Flange with Class150–Class2500 and PN10–PN160 ratings. Ideal for low-pressure and general industrial use. It is named for its "sliding installation" feature and is commonly used in medium and low-pressure applications with non-intensive vibration conditions.
We offer a full range of stainless steel, duplex, and flange in various sizes to meet different standards.

What is a Slip-on flange?
A sliding flange is a pipe flange that slides to the end of a pipe and is secured with bolt holes aligned with pre-drilled holes.
Its design bore is slightly larger than the pipe diameter so that it can easily "slide in" before tightening. It is commonly used in low- to medium-pressure systems.
What are the advantages of sliding flanges?
This design allows for rapid assembly without requiring complex welding or alignment, making it ideal for time-sensitive projects.
Sliding flanges are generally cheaper than other flanges (such as welded neck or blind flanges) because their design and manufacturing process are simpler.
When should I use a sliding flange?
These flanges are not designed for high-pressure or high-temperature systems, making them ideal for standard applications where pressure is not a concern. Slip-on flanges are a cost-effective option when budget is a critical factor and the application does not require the strength and durability of more expensive flanges.
When should I not use a sliding flange?
Sliding flanges are not designed for high-pressure systems and may fail or leak under extreme pressure.
The design of sliding flanges does not provide the same vibration resistance as other flange types (such as welded or socket weld flanges), which can lead to connection failure over time.
