Understand the butt welded flange (WN) to ensure safe and reliable pipe connections

In industrial pipe system, Weld Neck Flange (WN) is one of the common pipe connection parts, its characteristics and application range are wide, which is essential to ensure the safety and reliability of pipe connection. Let's introduce the characteristics and application of butt welded flange (WN) :

Features:

Welding connection: The butt welded flange has the characteristics of welding connection, suitable for direct welding with the pipeline, the connection is firmly fastened, and the sealing performance is good.

Neck design: Butt welded flanges have a long neck design, also known as a welding neck, to strengthen the connection between the pipe and the flange and provide good rigidity and stability.

Round hole: The hole of the butt welded flange is round, suitable for use with the same shape flange, usually connected with bolts and nuts, and the sealing performance is reliable.

Scope of application:

High pressure and high temperature environment: butt welded flange is suitable for high pressure and high temperature working environment, such as petrochemical, oil refining, chemical engineering and other fields.

Important equipment connection: butt welded flanges are often used to connect important equipment and pipeline systems, such as boilers, heat exchangers, pressure vessels, etc.

Standard specification:

The production and use of butt welded flanges usually follow international standards or industry codes, such as ANSI/ASME, DIN, JIS, etc.

These standards specify the size, material, manufacturing process and connection mode of butt welded flanges to ensure that their quality and safety performance meet the requirements.

In summary, understanding the characteristics and application range of butt welded flanges (WN) is essential for the correct selection of suitable pipe connection components. In the process of engineering design and pipeline installation, we will select butt welding flanges that meet the requirements of standard specifications according to the specific working conditions and requirements, to ensure that the pipeline connection is safe and reliable, and to provide reliable guarantee for industrial production.
