Introduction
In industrial piping systems, flanges play a crucial role in connecting pipes, valves, pumps, and other equipment securely. Among the various types of flanges available, forged flanges stand out for their superior strength, durability, and reliability. At DingYang, we specialize in manufacturing high-quality forged flanges that meet stringent industry standards, ensuring optimal performance in demanding applications.
What is a Forged Flange
A forged flange is a type of pipe flange produced through the forging process, which involves shaping metal under high pressure and temperature. Unlike cast flanges, forged flanges have a denser grain structure, making them stronger and more resistant to impact, pressure, and extreme temperatures.
Key Advantages of Forged Flanges
High Strength & Durability – The forging process enhances the mechanical properties of the metal, ensuring excellent load-bearing capacity and resistance to wear.
Superior Leak Prevention – Tight grain structure minimizes porosity, reducing the risk of leaks in high-pressure systems.
Wide Temperature & Pressure Tolerance – Suitable for extreme conditions in oil & gas, petrochemical, and power generation industries.
Long Service Life – Resistant to corrosion and fatigue, reducing maintenance costs over time.
Types of Forged Flanges Offered by DingYang
At DingYang, we produce a wide range of forged flanges to meet diverse industrial needs
1. Weld Neck Flanges (WN)
Designed for high-pressure applications.
Features a tapered hub for smooth stress distribution.
Ideal for critical pipelines in oil refineries and chemical plants.
2. Slip-On Flanges (SO)
Easy to install and align.
Suitable for low-pressure systems.
Commonly used in water treatment and HVAC systems.
3. Blind Flanges (BL)
Used to seal the end of piping systems.
Essential for pressure testing and maintenance shutdowns.
4. Socket Weld Flanges (SW)
