FLANGE MS 2"

FLANGE MS 2" 

An MS 2"  Flange (Mild Steel 2-inch Flange) is a heavy-duty, circular metal plate used to connect a 2-inch nominal bore (NB) pipe to valves, pumps, or other piping segments to create a secure, leak-proof system. The term "Big" in industrial contexts typically differentiates a heavy-duty plate flange, a larger standard table variation (like a high-pressure ASA 150/300# or heavy DIN standard), or a flange with an expanded outer diameter (OD) and thick plate profile designed for high-stress agricultural or industrial systems.

Below is a detailed breakdown of its specifications, applications, and primary types.

⚙️ Technical Specifications & Dimensions

While exact dimensions can vary slightly depending on the design standard (such as BS 10 or ASME B16.5), a heavy-duty or "big" 2-inch MS flange typically features the following structural specs:

• Material: Mild Steel (MS), frequently conforming to structural grades like IS 2062 Grade A/B or ASTM A105 forged carbon steel.

• Nominal Size: 2 inches (50 mm NB), meaning it perfectly matches a pipe with a 2-inch internal flow diameter.

• Outer Diameter (OD): Typically ranges from 140 mm to 152 mm depending on the standard table used.

• Thickness: Ranges from a basic 4 mm for low-pressure agricultural use up to 12 mm – 19 mm for heavy-duty industrial/forged configurations.

• Surface Coating: Usually finished with black anti-rust paint, red oxide primer, or hot-dip galvanization (GI) to prevent rus
