Inconel 625 Nickel Alloy Flange for High Pressure and Corrosion Resistant Piping

Product Introduction

Inconel 625 Nickel Alloy Flange is a high-performance piping component designed for high-pressure, high-temperature and corrosive service environments. Made from Alloy 625 / UNS N06625, it offers excellent corrosion resistance, high mechanical strength and good resistance to pitting and crevice corrosion.

Our Inconel 625 Nickel Alloy Flange for High Pressure and Corrosion Resistant Piping is widely used in chemical processing, offshore engineering, marine piping, oil and gas systems, heat exchangers and other demanding industrial piping applications.

Different flange types, sizes, pressure classes and sealing faces can be supplied according to project specifications.

Product Specifications

Main Applications

Inconel 625 Flanges are suitable for piping systems exposed to pressure, corrosive chemicals or chloride-containing environments, including:

• Chemical processing plants
• Oil and gas pipelines
• Offshore platforms
• Marine piping systems
• Seawater systems
• Heat exchangers
• Pressure vessels
• Petrochemical equipment
• Power generation systems
• High-pressure industrial piping

The strong corrosion resistance of Nickel Alloy 625 Flange makes it especially suitable for marine, offshore and chemical service.
