2 Galvanized Pipe Flange

The 2-inch galvanized pipe flanges are essential connectors in piping systems, combining robust functionality with excellent corrosion resistance. These flanges are specifically designed to interface seamlessly with 2-inch nominal diameter galvanized pipes, making them ideal for a variety of applications, from residential plumbing to industrial fluid transfer systems.

In terms of specifications, the 2-inch galvanized pipe flanges typically feature an outer diameter of approximately 88.9mm, conforming to standard industry measurements. The flange thickness usually ranges from 6 to 8mm, providing sufficient strength to withstand pressures up to 16 bar, ensuring a secure and leak-proof connection. With a standard bolt hole pattern, these flanges commonly have four evenly spaced holes, which are designed to accommodate bolts that tightly fasten the flanges together. This configuration distributes stress evenly, enhancing the overall stability of the piping system.

Constructed from high-quality carbon steel, these flanges first leverage the inherent strength and durability of the base material. Subsequently, through the hot-dip galvanization process, a thick, adherent zinc coating is applied. This zinc layer acts as a sacrificial barrier, protecting the underlying steel from rust and environmental degradation. Whether exposed to moisture in plumbing setups or corrosive elements in industrial environments, the galvanized coating ensures a prolonged service life.

Production of these flanges adheres to strict international standards. In the U.S., ANSI/ASME B16.5 governs dimensions, pressure ratings, and face types, ensuring compatibility across different components. ASTM A123 specifies requirements for the galvanization process, mandating minimum coating thickness and adhesion quality. In Europe, DIN standards play a similar role, covering material composition, dimensional tolerances, and surface finish. These regulations guarantee that 2-inch galvanized pipe flanges deliver consistent quality, reliability, and safety in diverse piping applications.
