Everything You Need to Know About Nickel 200/201 Flanges – Properties, Applications, and Benefits

Nickel 200/201 Flanges are a crucial component in piping systems where corrosion resistance and high performance are essential. Known for their durability and purity, these flanges are crafted from commercially pure wrought nickel. At Sandvik, we supply a comprehensive range of Nickel 200/201 Flanges Manufacturers options to meet the demanding needs of industries such as chemical processing, marine, and power generation.

So, what exactly are Nickel 200/201 Flanges? These flanges are made from two closely related grades of nickel alloy—Nickel 200 and Nickel 201. Nickel 200 is a commercially pure (99.6%) wrought nickel, while Nickel 201 is a low-carbon variant designed to resist embrittlement from graphitization. The low carbon content in Nickel 201 makes it suitable for service above 600°F (315°C), where Nickel 200 might lose strength. Both grades offer excellent mechanical properties and high resistance to a range of corrosive environments.

One major advantage of Nickel 200/201 Flanges is their exceptional corrosion resistance in reducing and neutral media. They perform well in caustic alkalis and have excellent thermal and electrical conductivity. Their magnetic and mechanical properties remain consistent across wide temperature ranges. Sandvik, one of the top Nickel 200/201 Flanges Suppliers, ensures that every flange we provide meets international standards for strength and reliability.

In terms of application, Nickel 200/201 Flanges are used across multiple industries. In the chemical processing industry, they handle corrosive substances like caustic soda and acid solutions. In power generation, they’re used in heat exchangers, condensers, and piping systems due to their heat resistance. The marine industry relies on them for components exposed to saltwater. They are also critical in food processing, synthetic fiber production, and aerospace due to their non-reactive and stable properties. As one of the trusted Nickel 200/201 Flanges Stockists, Sandvik keeps a wide inventory to support rapid supply across industries.

Nickel 200/201 Flanges come in several types, each suited for specific applications:

Weld Neck Flanges: Ideal for high-pressure applications, these flanges are welded to the pipe to provide strength and resistance to dishing.

Slip-On Flanges: These are easy to install and ideal for low-pressure systems. They are slipped over the pipe and then welded on both sides.

Blind Flanges: Used to close pipe ends, these flanges allow for easy access to the pipe system for inspection or modification.

Socket Weld Flanges: Suitable for small diameter pipes, offering a smooth bore and better flow characteristics inside the pipe.

Lap Joint Flanges: Used with stub ends in systems requiring frequent dismantling for inspection or cleaning.

Threaded Flanges: Ideal for systems where welding is not an option. These screw directly onto the pipe, offering easy installation and maintenance.

Sandvik stands out as one of the leading Nickel 200/201 Flanges Exporters, delivering precision-engineered flanges to customers around the globe. Our products are manufactured with strict quality control and come with full traceability, ensuring compliance with international standards like ASTM B564 and ASME B16.5.

In conclusion, Nickel 200/201 Flanges offer a perfect combination of corrosion resistance, thermal stability, and mechanical strength. Whether you’re working in chemical plants, marine systems, or high-temperature environments, these flanges provide the performance you need. Choose Sandvik for unmatched quality, availability, and technical expertise in Nickel alloy flanges.
