When it comes to connecting pipes in industrial projects, choosing the right flange is critical for efficiency, safety, and cost control. Among the many options available, slip on flanges (SO flanges) stand out as one of the most commonly used connection types. Known for their practicality and reliability, slip on flanges are widely applied in pipelines that transport water, oil, gas, and other fluids under moderate pressure and temperature conditions.
So, what makes slip on flanges such a popular choice? Let’s take a closer look at their advantages.
1. Lower Installation Costs
Slip on flanges are more economical compared to many other flange types. Because they require less precision in pipe cutting and preparation, both material and labor costs are reduced. This makes them an attractive option for large-scale projects where cost-efficiency is essential.
2. Easy Alignment During Installation
One of the greatest benefits of slip on flanges is their ease of alignment. Since the pipe simply slides into the flange bore, installers can easily position and adjust it to achieve proper fit before welding. This minimizes the risk of misalignment and ensures a smoother installation process.
3. Better Leak-Proof Performance
Slip on flanges are welded on both the inside and outside of the flange. This double-welding feature not only enhances the overall strength of the joint but also provides excellent resistance to leaks. As a result, these flanges are particularly suitable for pipelines that require reliable sealing performance.
4. Reduced Cutting Time for Pipes
Unlike weld neck flanges, which require precise cutting and beveling of pipes, slip on flanges demand less accuracy in pipe cutting. The pipe only needs to be inserted into the flange, which reduces preparation time and simplifies the workflow.
5. Compatibility with Lower Hub Design
The design of slip on flanges includes a lower hub, which improves their strength and durability while still keeping them easy to install. This design also makes them suitable for pipelines with moderate pressure applications, where both reliability and ease of use are equally important.
Conclusion
Slip on flanges combine economy, convenience, and reliability, making them a go-to solution in many industrial sectors. Their ability to provide strong, leak-resistant connections while saving time and installation costs makes them highly versatile for a wide range of piping systems.
If you’re looking for a practical flange solution for your next project, slip on flanges may be exactly what you need.
