Get uncompromising strength, corrosion resistance, and reliability where it matters most with Alloy 200/201 (ASTM B564) Welding Neck Flanges. Designed for demanding chemical, petrochemical, and high-temperature applications, these nickel alloy flanges deliver exceptional performance and long-term durability, even in harsh, corrosive environments.
Key Advantages
Superior corrosion resistance: High-purity nickel composition provides outstanding resistance to caustic alkalis, neutral salts, and reducing chemicals—ideal for harsh process conditions.
Excellent mechanical strength: Robust construction and high tensile strength ensure reliable performance under pressure, temperature fluctuations, and mechanical stress.
Seamless weldability: The welding neck design offers smooth stress distribution and easy, secure welding to piping systems, reducing the risk of leaks and fatigue failures.
ASTM B564 compliant: Manufactured to ASTM B564 standards for Alloy 200/201, ensuring consistent quality, precise dimensions, and industry-approved performance.
Versatile industrial use: Perfect for chemical processing, power generation, marine, oil and gas, and any environment where standard steel flanges fail prematurely.
Technical Specifications
Exceptional corrosion resistance: Made from high-purity nickel alloys (Alloy 200/201), these flanges offer excellent resistance to caustic alkalis, neutral and alkaline salt solutions, and dry gases – ideal for chemical processing, petrochemical, and power generation industries.
High mechanical strength: Alloy 200/201 combines robust tensile strength with toughness, ensuring long service life even under high pressure, high temperature, and cyclic loading conditions.
Superior weldability: The welding neck design ensures a smooth, gradual stress distribution between flange and pipe, reducing the risk of fatigue and structural failure.
