Features:

1. High pressure resistance:

Suitable for high-pressure environments, flanges of different grades can be selected according to needs to meet different pressure requirements.

2. Corrosion resistance:

Suitable for environments with high requirements for corrosion resistance and can be used to handle various chemical media.

3. Butt welding connection:

The butt-welding connection method with the pipeline ensures good sealing and connection stability.

Advantages and disadvantages:

Advantages:

1. Suitable for high-pressure environments: flanges of different pressure levels can meet different high-pressure requirements.

2. Corrosion resistance: capable of handling various chemical media, suitable for environments with strong corrosiveness.

3. Stability of butt-welding connection: By welding connection, a relatively stable pipeline connection is ensured.

Disadvantages:

1. High manufacturing and installation costs: Compared to other connection methods, professional equipment and technology are required for butt welding, which may result in higher manufacturing and installation costs.

2. Additional maintenance may be required: The welded structure may require regular maintenance and inspection to ensure the integrity and stability of the connection.

The weld neck flange under BS3293 standard is suitable for industrial applications with high requirements for pressure resistance and corrosion resistance, especially when dealing with chemical media or high-pressure situations. However, like other welded flanges, factors such as manufacturing cost, installation complexity, and maintenance requirements need to be considered.
