Our Plate Flanges are widely recognized for their exceptional corrosion resistance, high mechanical strength, excellent dimensional accuracy, superior weldability, and long-lasting performance in demanding industrial environments.
UNS N02201 Nickel Alloy 201 is a commercially pure wrought nickel alloy with a controlled low-carbon composition. Compared to Nickel 200, Nickel Alloy 201 offers improved resistance to graphitization during prolonged exposure to temperatures above 315°C. The alloy provides outstanding resistance to caustic alkalis, reducing chemicals, neutral salts, organic compounds, distilled water, and many corrosive process media. These characteristics make Nickel Alloy 201 one of the preferred materials for manufacturing industrial plate flanges used in aggressive chemical and high-temperature applications.
Nickel Alloy 201 Plate Flanges are manufactured by machining flat nickel alloy plates into flange configurations suitable for low-pressure and medium-pressure piping systems. These flanges are commonly used in chemical processing plants, offshore platforms, marine engineering, desalination systems, pharmaceutical manufacturing, food processing industries, refineries, fertilizer plants, LNG terminals, and power generation facilities where superior corrosion resistance and reliable performance are essential.
At Synergy Engineering Solution, every UNS N02201 Nickel Alloy 201 Plate Flange is manufactured using modern CNC machining technology, precision fabrication equipment, and strict quality assurance procedures. Each flange undergoes detailed dimensional inspection, chemical analysis, mechanical testing, and non-destructive examination to ensure full compliance with international quality standards before dispatch.
UNS N02201 Nickel Alloy 201 Plate Flanges are high-quality industrial flanges manufactured from Nickel Alloy 201 plates for connecting pipes, valves, pumps, pressure vessels, and process equipment. These flanges provide excellent sealing performance while ensuring easy installation, maintenance, and long service life. Their outstanding corrosion resistance makes them highly suitable for handling aggressive chemicals, alkaline solutions, and high-purity process fluids.
The low carbon content of Nickel Alloy 201 significantly improves resistance to intergranular attack during prolonged exposure to elevated temperatures. This property makes these plate flanges particularly suitable for chemical reactors, heat exchangers, evaporators, storage tanks, piping systems, and industrial processing plants where high operating temperatures and corrosive environments are common.
