Stainless Steel Forged Welding Neck Flange SS304 SS316 SS321

Product Data

Product Introduction

Stainless steel is an alloy steel consisting of iron, carbon, and other elements, usually chromium and nickel. It gets its name from its good anti-corrosion performance, which enables it to resist oxidation, corrosion and rust, so it is widely used in various fields.

The main components of stainless steel include:

• Iron: The main base metal of stainless steel, giving it good strength and mechanical properties.
• Carbon: The carbon content is generally low and has no significant effect on the corrosion resistance of stainless steel, but affects hardness and weldability.
• Chromium: It is one of the main alloying elements of stainless steel, and its content is usually above 10.5%. The presence of chromium forms a stable oxide film (chromium oxide) on the surface, called “oxide film” or “chromium oxide layer”, which prevents oxygen from reacting with iron, thereby effectively preventing rust.
• Nickel: Nickel is another important alloying element that improves the corrosion resistance and toughness of stainless steel.

In addition to chromium and nickel, there are other alloying elements, such as molybdenum, titanium, copper, manganese, etc., which can be added to stainless steel according to specific needs to obtain specific properties.

Application:

• Construction industry: used to make bridges, building structures, handrails, railings, etc.
• Manufacturing: Components of automobiles, aerospace, ships, trains and other means of transportation.
• Kitchen utensils: pots, knives, cutlery, etc.
• Medical equipment: surgical instruments, operating tables, etc.
• Food Processing: Food manufacturing and storage equipment.
• Chemical industry: corrosion-resistant equipment such as pipes and containers.

Overall, stainless steel plays an indispensable role in modern society due to its high strength, good corrosion resistance and aesthetic appearance.

A welding neck flange is a type of flange used in piping systems to connect pipes, valves, pumps, and other equipment. It is one of the most commonly used flange types due to its strong and reliable connection.

Key features

1. Neck: The distinguishing feature of a welding neck flange is the long tapered neck that extends from the flange’s flat circular base. The length and thickness of the neck may vary based on the flange’s pressure rating and application.
2. Welding: The welding neck flange is designed for butt welding to the pipe. The neck provides a smooth transition from the flange to the pipe, making it easier to create a strong and leak-free joint by welding the neck to the pipe.
3. Raised Face: Most welding neck flanges have a raised face around the sealing surface. The raised face helps to create a better seal when the flange is bolted to another flange or equipment.

Advantages

• High Strength: The welding neck design provides excellent structural strength and rigidity, making it suitable for high-pressure and high-temperature applications.
• Leak Resistance: The welded connection between the neck and the pipe ensures a robust and leak-resistant joint.
• Easy Alignment: The long neck allows for easy alignment of the flanges during installation, reducing the chances of misalignment.
• Smooth Flow: The gradual transition from the flange’s bore to the pipe’s bore results in a smooth flow path, reducing turbulence and pressure drop.

Welding neck flanges are commonly used in critical applications, such as oil and gas processing, petrochemical plants, power generation, and other industries where high pressure and temperature conditions are prevalent. They are available in various materials, including carbon steel, stainless steel, alloy steel, and other specialty materials, depending on the specific requirements of the application.
