All ASME B16.5 A105N flanges were produced with precise machining on sealing surfaces and strict dimensional control to ensure proper alignment and leak-free performance during installation.

Advantages of ASTM A105N Carbon Steel Flanges

ASTM A105N is a normalized carbon steel commonly selected for pressure piping components due to its balanced mechanical strength and weldability. Combined with ASME B16.5 Class 150 design, these flanges are suitable for a wide range of operating conditions.

Key advantages include:

• Stable performance under moderate pressure
• Excellent weld compatibility with carbon steel pipes
• Standardized dimensions for easy replacement and maintenance
• Wide acceptance in oil & gas, petrochemical, and utility projects

The use of raised face (RF) flanges further enhances sealing reliability when paired with appropriate gaskets.
