This is a type of pipe flange that is designed to be slipped over the end of a pipe and welded in place. It is often referred to as a tapered hub flange or high-hub flange.
The weld neck slip-on flange transfers stress to the pipe, thus reducing the risk of high-stress concentration at the flange’s base. It is commonly used in various industries where reliable and durable connections are required. Most especially in high-pressure and high-temperature environments.

The weld neck slip-on flange stands out due to its unique design and construction. It offers several benefits over other types of flanges.
It features a long tapered hub that gradually transitions from the flange body to the pipe. This design provides added strength and reduces the stress concentration at the weld. This makes it suitable for high-stress applications.
The flange is welded to the pipe using a butt weld. It creates a strong and leak-proof connection. The slip-on design means that it is first slipped over the pipe before being welded in place. This ensures a precise fit.
The flange’s rim is drilled with evenly spaced bolt holes. It allows it to be securely attached to a bolted flange connection. This ensures a tight and stable connection between the pipes.
Most weld neck slip-on flanges have a raised face. It helps to create a more effective seal when combined with a gasket. This feature is particularly important in preventing leaks in high-pressure applications.
It is available in various materials to suit different applications. Common materials include carbon steel, stainless steel, and nickel alloys. These materials are selected based on their resistance to extreme temperatures, corrosion, and pressure.
The weld neck slip-on flange is widely used in several industries due to its versatility and reliability. Some of the common applications are listed below:
In this sector, weld neck slip-on flanges transport crude oil, natural gas, and refined products. The flanges are noteworthy for withstanding high pressures and temperatures.
These flanges are crucial in chemical processing plants. They connect pipes that carry corrosive and hazardous materials. The robust design results in a leak-proof connection. Thus, they greatly minimize the risk of chemical leaks.
Weld neck slip-on flanges are also found in power plants, especially in high-stress application lines. They can handle extreme conditions ensuring the safe and efficient operation of power generation systems.
In water treatment plants, these flanges are used in pipelines that transport treated water. In some cases, they are also found in desalination plants. Weld-neck slip-on flanges can connect pipes in high-pressure reverse osmosis systems.
Weld neck slip-on flanges are durable and resistant to corrosion. These make them suitable for use in marine environments and offshore oil rigs.
The weld neck slip-on flange has several advantages, making it a preferred choice for many industrial applications.
With its tapered hub and butt-weld connection, its design provides superior strength. This makes it capable of withstanding high pressures and temperatures, ensuring long-term durability.
The raised face design of the flange ensures a tight seal when combined with a gasket. It reduces the risk of leaks. This is particularly important in industries that handle hazardous or valuable fluids.
The gradual transition from the flange to the pipe minimizes the stress concentration at the weld. This feature enhances the integrity of the piping system.
It can be customized to suit specific needs. From high-temperature environments to corrosive conditions. Also, it is available in a wide range of materials.
It comes in various sizes. It is suitable for a broad range of piping systems, from small-diameter pipes to large industrial pipelines.
While the weld neck slip-on flange offers many benefits, there are also some disadvantages to consider:
Compared to other flange types, weld neck slip-on flanges are generally more expensive. The cost is justified by their superior strength and durability. But, it can be a drawback for budget-conscious projects.
Installing a weld neck slip-on flange requires precise alignment and skilled welding. This can make the installation process more time-consuming. It is also labor-intensive compared to other flange types.
The robust design of the weld neck slip-on flange makes it bulkier and heavier. This can be a disadvantage in applications where space is limited or weight is a concern.
Due to its size and weight, the weld neck slip-on flange is more prone to damage during transport. Care must be taken to protect the flange from bumps and impacts that could compromise its integrity.
