Product Overview: A105N Normalized Carbon Steel for High Strength and Full Coverage
This ASME B16.5 Forged Weld Neck Flange is our flagship carbon steel product, engineered for critical piping connections demanding the highest safety ratings. We utilize ASTM A105N Normalized Carbon Steel, ensuring the flange exhibits exceptional fatigue resistance and mechanical toughness under extreme temperature and pressure cycles.
The distinctive tapered hub design inherent to the Weld Neck structure guarantees a smooth transition of stress between the flange and the pipe, effectively preventing stress concentration and cracking at the weld joint. This results in long-term, leak-proof performance. We offer the widest market coverage in terms of size (DN15–DN3000) and pressure rating (Class 150–Class 2500), positioning us as your one-stop solution for high-pressure carbon steel flange procurement.
