Monel Welding Neck Flanges

A weld neck flange, one of the most common types of flanges, features a long inching hub that can be welded with a pipe. This flange type is used, typically, in high-pressure and high/ low temperatures applications that want an unrestricted inflow of the fluid conveyed by the pipeline.

As a leading supplier and manufacturer in China, GNEE Steel provides cost-effective nickel-based alloy products.

Product Introduction

Monel weld neck flanges are made of a nickel-copper alloy that offers high strength, hardness and good rust resistance over a wide heating range. Monel weld neck flanges have excellent resistance to sulfuric and hydrochloric acids. If the product is not cleaned after welding, there is a risk of embrittlement and contamination.

Features of Monel Weld Neck Flange:

Monel weld neck flanges have a perfect combination of properties such as high tensile strength, excellent surface quality, high durability, excellent corrosion resistance and long service life. Monel weld neck flanges have extraordinary resistance to acidic and alkaline media. These flanges have high mechanical strength, weldability and machinability. It is resistant to corrosion, seawater, acidic solutions, salts and steam. Due to these characteristics, we use pure high-quality alloys to manufacture weld neck flanges with excellent strength and resistance. They will be welded using conventional welding techniques to connect or disassemble. Elements such as nickel and copper are used in Monel weld neck flanges. Due to these elements, Monel weld neck flanges have high tensile strength and toughness.
