6 Inch Slip on SO Flanges

 

SO Flange

Slip on flange, also called SO flange. It's a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, that is designed to slide over the end of a pipe. The SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.

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.

Cost-Effective Solution

The design of SO flanges is relatively simple, resulting in less manufacturing complexity and lower production costs than other types. This affordability makes them ideal, especially for projects with budget constraints. Furthermore, the reduced welding material results in cost savings on consumables like welding rods or wires.

Availability and Compatibility

They are conveniently accessible in various sizes, materials, and pressure ratings, simplifying the search for the ideal flange that meets specific needs. Moreover, they exhibit compatibility with diverse types of pipes and fittings, allowing for versatility in their usage. This compatibility extends to various materials including carbon, steel, and alloy materials enabling seamless integration with different systems.

Space Efficiency

SO flanges have a compact and streamlined design. They have a flat face, unlike weld neck or socket weld flanges with protruding necks or socket extensions. This design minimizes the overall footprint of the flange, allowing for more efficient use of space within the piping system. They also have a shorter length compared to other types.

 

 
Key Features of Slip-On Flanges:
 
01/

Design:
Slip-on flanges have a flat face and are typically welded to the pipe after being slipped over it. This design allows for easy alignment and installation.

02/

Installation:
They are easier to install compared to other flange types, as they do not require precise alignment of the pipe ends. The flange can be positioned and then welded in place.

03/

Applications:
Slip-on flanges are commonly used in low-pressure applications and are suitable for various industries, including oil and gas, water treatment, and chemical processing.

04/

Cost-Effectiveness:
Generally, slip-on flanges are more cost-effective than other types of flanges, such as weld neck flanges, due to their simpler design and installation process.

05/

Cost-Effectiveness:
Generally, slip-on flanges are more cost-effective than other types of flanges, such as weld neck flanges, due to their simpler design and installation process.

06/

Limitations:
While slip-on flanges are versatile, they may not be suitable for high-pressure applications due to the potential for leakage at the weld joint.
