What information is required for customizing a fan flange?

  When customizing fan flanges, the following key information is usually required to ensure that the customized product meets the requirements:

1. Technical specifications and parameters

Nominal diameter: It indicates the size of the flange-connected pipeline or equipment and serves as an important reference for model selection. It is necessary to specify the nominal diameter of the required flange to ensure that it matches the dimensions of the pipeline or equipment.

Nominal pressure: It represents the maximum allowable working pressure of a flange at a specified reference temperature and is one of the key parameters for flange design and selection.

Flange type: Select the appropriate flange type based on the connection method, material, and pressure rating.

Sealing surface type: The sealing surface types of flanges include full face, raised face, concave-convex face, tongue-and-groove face, and ring joint face. It is necessary to select the appropriate sealing surface type according to the sealing requirements.

Dimensions and Tolerances: Provide specific dimensional information such as the outer diameter, thickness, bolt hole diameter, and bolt hole count of the flange, and specify the dimensional tolerance requirements to ensure the machining accuracy and interchangeability of the flange.
