When it comes to piping systems, the right connection is key to ensuring durability and safety. You may already be familiar with plate flanges, but let’s talk about a specific type: the slip-on flange.
Stainless steel slip-on flanges are versatile and widely used in various industries due to their ease of installation and reliability. But what makes them unique, and why might you choose a slip-on flange for your next project?
What is a slip-on flange? A slip-on flange (sometimes called a “slip-in flange”) is a ring that fits over the pipe’s end. It is welded both inside and outside to provide a secure connection.
The stainless steel construction makes it resistant to corrosion and suitable for a range of applications where long-lasting, durable connections are required. Unlike other flange types that require complex installation, slip-on flanges are easier to position and weld, making them a practical choice for many industries.
Slip-on flanges are straightforward to install. Because the pipe slides through the flange, there’s no need for precise alignment before welding. This design allows you to position the flange accurately before welding it in place, simplifying the entire installation process.
When compared to other flange types, such as weld neck flanges, slip-on flanges tend to be more economical. Their design requires less precision in cutting and positioning, which translates to reduced installation costs and time savings.
Stainless steel slip-on flanges are incredibly versatile. Thanks to their corrosion-resistant properties, they’re suitable for environments exposed to water, chemicals, or high humidity. This makes them an ideal choice for various industries, from oil and gas to food processing.
Slip-on flanges are often used in low to moderate-pressure applications. Since they are not as robust as weld neck flanges, they are best suited for systems where high pressure is not a concern but where durability and resistance to corrosion are important.
Slip-on flanges and plate flanges serve similar purposes but have distinct differences. Here’s a quick comparison:
Feature | Slip-On Flange | Plate Flange |
Design | Slides over the pipe; welded on both inside and outside | Flat disc; usually welded or bolted to the pipe |
Installation Ease | Easier to align and weld | Requires precise alignment |
Pressure Suitability | Ideal for low to moderate pressure applications | Suitable for low to moderate pressure; less versatile |
Material Cost | Slightly higher due to dual welding but lower installation costs | More economical but requires careful installation |
Due to their versatility and ease of use, slip-on flanges find their way into a range of applications:
In plumbing and water treatment, slip-on flanges are favored for their corrosion resistance and easy installation. They provide a durable connection that withstands water exposure.
Stainless steel’s corrosion resistance makes these flanges great for transporting chemicals or in food processing. The slip-on flange design also simplifies cleaning and maintenance.
In oil and gas systems, stainless steel slip-on flanges are often used in pipelines transporting low-pressure fluids or gas. They offer a reliable, leak-proof connection that can be quickly installed or adjusted.
The quick assembly of slip-on flanges makes them suitable for HVAC systems and fire protection piping, where reliability and speed of installation are crucial.
When choosing a slip-on flange, there are some essential considerations:
Stainless steel slip-on flanges come in various grades, such as 304 and 316 stainless steel. Make sure to choose the right grade for your environment. For example, 316 stainless steel offers higher corrosion resistance and is great for environments exposed to saltwater or harsh chemicals.
Understand the pressure and temperature limits of your system. Slip-on flanges are best for low to moderate-pressure applications, so if you’re dealing with high-pressure systems, consider an alternative flange type like a weld neck flange.
Ensure that the size of the slip-on flange matches the pipe and other components of your system. Proper sizing is essential for achieving a secure and leak-free connection.

What is the difference between a slip-on flange and a weld neck flange?
A slip-on flange slides over the pipe and is welded both inside and outside, while a weld neck flange is designed to be butt-welded to the pipe, providing a stronger connection suitable for higher pressures.
Can slip-on flanges be used in high-pressure applications?
Slip-on flanges are generally best for low to moderate-pressure applications. For high-pressure systems, weld neck flanges are a more secure option.
Why choose stainless steel for slip-on flanges?
Stainless steel provides excellent corrosion resistance, durability, and longevity, making it suitable for environments with water, chemicals, and varying temperatures.
Are slip-on flanges easy to install?
Yes, slip-on flanges are easier to install compared to some other flange types, as they require less precision in alignment and allow for easy positioning before welding.
