What Is a Slip On Flange?
A slip on flange is a type of pipe flange designed to slide over the end of a pipe before being welded into position. The internal diameter of the flange is slightly larger than the outside diameter of the pipe, allowing it to slip into place easily during installation.
Slip on flanges are commonly used in lower pressure piping systems and applications where ease of alignment and installation is important. They are frequently specified within petrochemical plants, water systems, process pipework and industrial manufacturing facilities. View the sectors that can benefit from slip on flanges.

Slip On Flanges for Multiple Industries
Slip on flanges are widely used across multiple industries due to their reliable performance, ease of installation and suitability for a broad range of pipework systems. Their versatility makes them a popular choice for both low and high-pressure industrial environments where dependable flange connections are required.
Within the petrochemical industry, slip on flanges are commonly used across processing systems, pipelines and storage facilities where durability and operational efficiency are essential. Oil and gas facilities also rely on slip on flanges throughout upstream, midstream and downstream infrastructure due to their practicality and compatibility with a wide range of piping configurations.
Power generation facilities frequently utilise slip on flanges within steam, cooling and process pipework systems where strong and reliable connections are required under demanding operating conditions. In water treatment environments, slip on flanges are often selected for their straightforward installation and suitability for fluid handling systems.
Slip on flanges are also widely used throughout process engineering and industrial manufacturing applications where efficient pipe alignment and dependable sealing performance are important. Offshore installations regularly specify slip on flanges for pipework systems operating within challenging marine and corrosive environments.
Across industrial pipework systems generally, slip on flanges remain a trusted and cost-effective solution for connecting pipes, valves, pumps and other essential components throughout complex infrastructure and processing facilities.
Slip On Flange vs Weld Neck Flange
Slip on flanges and weld neck flanges are both widely used within industrial pipework systems, but each offers different advantages depending on the application, pressure requirements and installation environment. Understanding the differences between the two can help ensure the correct flange type is selected for long-term performance and reliability.
Installation Differences
Slip on flanges are designed to slide over the pipe before being welded into position, making alignment and installation simpler and faster. Weld neck flanges feature a long tapered hub that is butt welded directly to the pipe, requiring more precise fitting and welding procedures.
Cost Considerations
Slip on flanges are generally more cost-effective due to their simpler manufacturing process and reduced installation time. Weld neck flanges often involve higher material and labour costs but may be preferred for critical applications requiring additional strength and durability.
Strength & Performance
Weld neck flanges are known for their excellent structural strength and ability to handle high stress conditions. Slip on flanges still provide strong and reliable performance across many industrial systems but are typically better suited to moderate pressure and temperature applications.
Typical Applications
Slip on flanges are commonly used across water treatment, general industrial pipework, manufacturing and lower pressure process systems. Weld neck flanges are frequently selected for critical service environments such as high-pressure pipelines, offshore systems and demanding petrochemical operations.
Pressure Suitability
Slip on flanges are suitable for a wide range of low to medium pressure systems where ease of installation and cost-efficiency are priorities. Weld neck flanges are typically preferred for high-pressure and high-temperature applications where maximum joint integrity is essential.
Choosing the Right Flange
The correct flange type will depend on factors such as pressure requirements, operating conditions, budget and system design. MDS Petrochemical can help advise on the most suitable flange solution for specific industrial applications and technical requirements.
Slip On Flange FAQs
What is a slip on flange used for?
A slip on flange is used to connect pipework, valves, pumps and other industrial components within a piping system. It slides over the end of the pipe before being welded into position, creating a secure connection that is commonly used across petrochemical, oil and gas, water treatment, process engineering and industrial pipework applications.
What is the difference between a slip on flange and weld neck flange?
The main difference is the way each flange is fitted to the pipe. A slip on flange slides over the pipe and is then welded, making it easier and quicker to install. A weld neck flange has a long tapered hub and is butt welded to the pipe, offering greater strength for higher pressure or more demanding applications.
Are slip on flanges suitable for high pressure systems?
Slip on flanges can be used across a range of pressure ratings, but they are generally more common in low to medium pressure systems. For very high-pressure or high-temperature applications, weld neck flanges may be more suitable due to their stronger connection and improved stress distribution.
What materials are slip on flanges available in?
Slip on flanges are available in a wide range of materials including carbon steel, stainless steel, duplex, super duplex, nickel alloy and high yield grades. The most suitable material will depend on the application, temperature, pressure, corrosion risk and industry requirements.
What standards do slip on flanges follow?
Slip on flanges can be manufactured and supplied to recognised standards including ANSI, ASME, DIN and BS specifications. These standards help define dimensions, pressure ratings, materials and performance requirements for industrial pipework systems.
What sizes are available?
Slip on flanges are available in a broad range of sizes to suit both small and large diameter pipework systems. They can also be supplied in different pressure classes, material grades and flange facings depending on the technical requirements of the project.
