Welding Plate Flange

Product Overview:
The Welding Plate Flange is a widely used pipe connection component designed to be welded directly to the end of a pipe. Made from high-quality steel plate, this flange type is economical and simple to install, making it ideal for low- and medium-pressure piping systems. Its flat surface ensures easy welding and a tight, leak-proof seal when used with gaskets.

Key Features:

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

• Type: Flat welding flange (plate flange, no neck)

• Size Range: DN15–DN3000 (1/2"–120")

• Pressure Rating: PN6–PN25 / Class 150–Class 300

• Standards: ANSI, DIN, JIS, EN, GB, or customer specifications

• Surface Finish: Anti-rust oil, black paint, galvanizing, epoxy, or custom coating

Advantages:

• Simple structure, easy to fabricate and weld
