Inconel 625 Flange UNS N06625 Nickel Alloy Pipe Flange for Oil & Gas
Inconel 625 (UNS N06625) flange is a high-performance nickel-based alloy flange designed for extreme service conditions including high temperature, high pressure, and severe corrosive environments. It delivers outstanding mechanical strength, excellent corrosion resistance, and long-term reliability for critical industrial piping systems.
Manufactured in strict compliance with ASTM B366, ASME B16.5, and ASME B16.47 standards, Inconel 625 flanges are available in various types such as weld neck, slip-on, blind, socket weld, and lap joint flanges. They feature precise dimensions, uniform wall thickness, smooth surface finish, and stable structural integrity to ensure tight, leak-proof connections.
Inconel 625 flange exhibits superior resistance to pitting, crevice corrosion, stress corrosion cracking, and oxidation. It maintains excellent mechanical properties at both cryogenic temperatures and elevated temperatures up to 1093°C, making it suitable for applications where carbon steel and stainless steel cannot meet performance requirements.
This nickel alloy flange is widely used in oil and gas exploration, offshore platforms, petrochemical plants, chemical processing, marine engineering, power generation, heat exchangers, and high-pressure pipeline systems. Its excellent weldability and formability allow for easy installation and maintenance.
With exceptional durability, high creep strength, and excellent resistance to hostile media, Inconel 625 flange greatly reduces maintenance costs and extends service life in the most demanding operating conditions.
