Flat Face Forged Flanges A182 F22 Class 3 WN Flange
Product Overview
The Welding Neck Flange is a critical component in piping systems, widely recognized for its robust design and superior performance in demanding applications. Designed specifically for high-pressure and high-temperature environments, these flanges are essential for industries requiring reliable and durable connections, such as chemical plants, oil and gas refineries, and power generation facilities.
Featuring a tapered hub and long neck design, this flange provides excellent reinforcement in high-stress applications. The neck's gradual transition from flange thickness to pipe wall thickness minimizes stress concentration, enhancing overall mechanical strength and integrity.

Frequently Asked Questions
What is a Welding Neck Flange and where is it commonly used?
A Welding Neck Flange is a type of flange with a long tapered hub that is welded to a pipe. It is commonly used in high-pressure and high-temperature applications such as oil and gas, chemical, and power industries due to its strength and durability.
What materials are Welding Neck Flanges typically made from?
Welding Neck Flanges are typically made from carbon steel, stainless steel, alloy steel, and sometimes exotic materials like Inconel or Monel, depending on the application requirements and environmental conditions.
How is a Welding Neck Flange installed?
A Welding Neck Flange is installed by butt welding the flange's neck to the pipe. This provides a smooth transition from flange to pipe, minimizing stress concentration and ensuring a strong, leak-proof joint.
What are the pressure ratings available for Welding Neck Flanges?
Welding Neck Flanges are available in a variety of pressure ratings, commonly ranging from ANSI Class 150 to Class 2500, allowing them to be used in low to very high-pressure systems.
Can Welding Neck Flanges be customized in terms of size and thickness?
Yes, Welding Neck Flanges can be customized to meet specific size, thickness, and dimensional requirements as per industry standards like ASME, ANSI, or API to fit particular piping systems.
