BS4504 RF ASTM A105 PN16 SO Flange Features and Applications

The BS4504 RF ASTM A105 PN16 SO flange is a widely used slip-on (SO) flange that meets BS4504 standards, designed for pressure nominal (PN) 16 applications. Manufactured from ASTM A105 carbon steel, this flange is known for its strength, durability, and suitability for low to medium pressure piping systems.

Key Features of BS4504 RF ASTM A105 PN16 SO Flange

1.Standard Compliance

This flange adheres to the BS4504 standard, making it suitable for European and international piping systems that follow metric dimensions. It is commonly used in water supply, HVAC, and general industrial pipelines.

2.Material: ASTM A105 Carbon Steel

Made from ASTM A105, a high-quality carbon steel, this flange offers excellent mechanical properties, including good tensile strength, impact resistance, and weldability. It is ideal for applications that require moderate temperature and pressure resistance.

3.Slip-On (SO) Design

The SO (Slip-On) flange is designed to slide over the pipe before being welded. This makes installation easy and cost-effective, as it requires less precision in pipe cutting compared to other flange types.

4.Raised Face (RF) Sealing Surface

The RF (Raised Face) design improves sealing efficiency, making it compatible with gaskets that enhance the leak-tightness of the connection. This feature is essential in applications where fluid containment is critical.

5.PN16 Pressure Rating

The PN16 classification means this flange is rated for 16 bar (232 psi) of pressure at ambient temperature. It is suitable for moderate-pressure water systems, steam, and general industrial fluid transport.
