When using weld neck flanges, the following points should be noted:

1. Before installation, check whether there are obvious defects or damages on the surface of the WN flange and pipeline to avoid problems such as loose connections or leakage of liquid or gas.

2. When purchasing welding neck flanges, different materials, models, and other parameters should be selected according to the specific usage situation.

3. During installation, it is necessary to follow the corresponding specifications and requirements to avoid improper installation that may affect the effectiveness of use.

4. During use, regular inspections and maintenance should be carried out to promptly address issues and ensure the normal operation of the pipeline system.

Weld Neck Flange Dimensions

The flange forging process generally consists of the following steps: selecting high-quality steel bars for cutting, heating, forming, and cooling after forging. The forging process methods include free forging, die forging, and membrane forging. During production, different forging methods are selected based on the quality of the forgings and the number of production batches.

A flange is a component that connects pipes to each other, used for connecting pipe ends; Also used is a flange at the inlet and outlet of the equipment, used for connecting two devices.
