Superior Strength and Fatigue Resistance SO Weld Neck Flange ASMEB16.5 Class150-2500

Superior Strength and Fatigue Resistance SO Weld Neck Flange ASMEB16.5 Class150-2500

1. Product Description 
A Hubbed Slip-On Flange (SO Flange) is a type of pipe flange where the pipe is inserted into the flange's hub and connected by fillet welds . It features a short, tapered hub that provides greater strength and load-bearing capacity compared to a flat, plate-type slip-on flange . Common international standards include the European system (PN series) and the American system (Class series) .

3. Product Applications 

SO Flanges are widely used in various industrial piping systems for connecting pipes, valves, and other equipment . They are a common sight in:

Petrochemical Plants

Oil and Gas Pipelines

General Industrial Piping for water, steam, and other media.

4. Product Advantages 
Higher Strength: The short hub provides reinforcement, offering better strength and load-bearing capacity than flat slip-on flanges, making them suitable for higher-pressure applications .

Cost-Effective: Generally, they have a lower material and manufacturing cost compared to Weld Neck flanges (WN) .

Ease of Installation: The design makes it easier to align the pipe with the flange during assembly compared to other types like Weld Neck flanges .
