Nickel Alloy Flanges

Home -

Nickel alloy flanges are strong mechanical fittings made from nickel-based alloys used to connect pipes and equipment in systems subjected to harsh conditions. They are crucial for demanding industries due to their excellent strength, durability and resistance to corrosion at high temperatures. Commercially pure nickel in grades 200 and 201, as well as high-performance alloys like Inconel, Monel, Hastelloy, and Incoloy, are common grades. Their exceptional resistance to oxidation and corrosion is attributed to their chemical composition which typically consists of nickel 99.0% min, iron 0.40%, copper 0.25%, manganese 0.35%, and carbon 0.15%. A reputable producer of nickel alloy flanges, Metracore Alloys provides precisely engineered products for demanding applications.

Nickel alloy flanges sizes include sizes ranging from 1/2 NB to 60 NB and are manufactured in compliance with ASTM B564 and ASME SB564. They are reliable in harsh environments due to their exceptional corrosion resistance against chemicals, acids, and saltwater. They have a high melting point, do not warp under pressure, and remain stable at high temperatures. With strong mechanical properties and dimensional accuracy, they deliver secure, leak-free performance. Many grades are non-magnetic, which is useful in specific applications like magnetic shielding. Their excellent weldability and formability also allow easy fabrication and customization.

Nickel alloy flanges are used in industries where reliability under stress is crucial. In petrochemical and oil & gas plants they withstand corrosive chemicals and high-pressure fluids. In power generation, they connect piping in high-temperature environments such as nuclear reactors. Marine engineering relies on them for shipbuilding, offshore platforms and desalination plants because of their resistance to seawater. Purity and resistance to cleaning agents are crucial in the food, pharmaceutical and chemical processing industries.

Forging from premium raw materials, precise machining, heat treatment to improve properties, surface finishing and strict quality checks are all part of the manufacturing process.
