Understand the dimensions of flat welded flanges to ensure solid and reliable pipe connections

In industrial piping systems, flat welded flange is one of the common pipe connectors, and its size parameters are crucial to ensure the stability and tightness of the pipe connection. Here we introduce the size of flat welded flange and its related content:

Size parameters: The size of flat welded flange is usually determined by flange outer diameter (OD), flange thickness (T), flange aperture (H) and other parameters.

Flange outer diameter (OD) : The outer diameter of the flange refers to the outer diameter of the flange connection, usually in inches (inch) or millimeters (mm), common sizes include 1/2 inch, DN50, etc.

Flange thickness (T) : The thickness of the flange refers to the thickness of the connecting part of the flange to support the connection and ensure sealing performance, usually in millimeters (mm).

Flange aperture (H) : The flange aperture is the diameter of the hole in the flange for connecting the bolt, usually in inches or millimeters (mm).

Size standards: The size of flat welded flanges usually conforms to international standards or industry specifications, such as ANSI/ASME, DIN, JIS, etc. These standards specify the size range of flanges, tolerance requirements and connection methods, ensuring that flanges produced by different manufacturers can be used interchangeably.

Application scenario: Flat welded flange is widely used in general industrial pipeline system, such as petrochemical, chemical engineering, water treatment, food processing and other fields. They are suitable for pipe connections under normal temperature and pressure conditions, and are usually used to connect pipelines with small diameters and low pressure.

To sum up, it is important to know the size parameters of flat welded flanges for the correct selection of suitable pipe connection components. In the process of engineering design and pipeline installation, we will select flat welded flanges that meet the requirements of standard specifications according to the specific pipeline size and working conditions, to ensure that the pipeline connection is stable and reliable, and to provide reliable guarantee for industrial production.
