Thick walled plate flat welding flange

Product Overview:
The Thick-Walled Plate Flat Welding Flange is engineered for high-strength, high-pressure piping systems where added wall thickness is essential for durability and safety. Made from premium-grade steel, this flange provides a strong weld connection and excellent resistance to mechanical stress, thermal expansion, and corrosion.

Key Features:

• Material: Carbon steel, stainless steel, or alloy steel (customizable)

• Type: Flat welding flange (plate type with thick wall)

• Standards: ANSI, DIN, JIS, EN, GB, or per customer drawings

• Size Range: DN15–DN2000 (1/2"–80")

• Pressure Rating: PN10–PN100 / Class 150–Class 600

• Wall Thickness: Increased thickness for heavy-duty applications

• Surface Finish: Black paint, galvanized, rust-preventive oil, or custom coating

Advantages:

• Reinforced wall structure for enhanced strength and pressure resistance
