Difference Between Nickel Alloy 200 Flanges vs Nickel Alloy 201 Flanges
Nickel Alloy is known for its superior corrosion resistance, outstanding thermal and electrical conductivity, and dependability in high-purity and chemical processing environments. Both Nickel Alloy 200 and Nickel Alloy 201 are commercially pure nickel grades used in demanding industrial setups. Nickel Alloy 200 flanges stand out for their high strength, durability and strong resistance to caustic chemicals. They work especially well in alkaline systems, food processing units, marine settings and high-purity lines where stable thermal and electrical performance is critical. While Nickel Alloy 201 provides greater performance at higher temperatures due to its lower carbon content, Nickel Alloy 200 flanges continue to be the favored choice for most low to moderate temperature applications due to their mechanical strength and higher conductivity. For industries handling chemical fluids, seawater, or clean processing environments, Nickel Alloy 200 flanges provide the right mix of corrosion protection, purity, and mechanical stability without driving up cost. Nickel Alloy 200 flanges are a trusted and widely used for critical industries, offering the right mix of strength, purity, corrosion resistance, and value.

Nickel Alloy 200 Flanges Application
Nickel Alloy 200 flanges work well in the petrochemical industry for connecting pipelines that handle caustic soda, chlorine, and other strong alkalis. These flanges are used in the oil and gas industry to join pipes carrying sour gas or crude oil particularly in locations with high sulfur concentration. Power plants use them in heat exchangers and boilers where stable connections are needed for steam or hot water flow. In chemical plants, they connect vessels and process lines that carry acids and other reactive fluids. Offshore platforms rely on these flanges for pipe joints that face saltwater spray and changing pressure. Food processing units use them in piping systems that handle fats, oils and cleaning agents during production.
Our Packaging Standard
We pack every Nickel Alloy 200 flange using strong, export-grade materials to keep them safe during handling and shipping. Each flange is wrapped in HDPE or shrink film, fitted with protective end caps and stored in strong hardwood crates or on pallets.
