SF440 RST37.2 carbon steel reducing flange is used in place of standard flanges to allow for changes in pipe size. It eliminates the need for a standard reducer in the pipe. The flange consists of one specified diameter and a smaller bore diameter.
SF440 RST37.2 carbon steel reducing flange reducing flanges have the dimensions of a standard pipe flange size except for the bore and hub size and are considered an economical means of making pipe size conversions. Discover a variety of flanges, including weld neck, slip-on, and threaded end types. Reducing flange are an economical way to make transitions between different sizes of pipe but are rarely used in piping due to the large pressure loss. ASME B16.5 covers the dimensions of reducing flanges.

Purpose Of SF440 RST37.2 Carbon Steel Reducing Flange
Carbon steel reducing flange are widely used in water conservancy, electricity, power stations, pipeline accessories, industry, pressure vessels, etc.
Carbon steel reducing flange reducing flanges are also called large and small flanges. Except for the pipe diameter, the flange size is the standard flat welding flange size of the larger diameter of the two diameters, but the pipe diameter is smaller than the normal diameter of the flange.
This type of flange is generally not recommended for use. It is only used when the diameter of the equipment, pump nozzle is larger than the pipe to be connected, and the installation size does not allow the installation of a reducer or it is unreasonable to install several reducers. At present, reducing flanges are limited to PN ≤ 2.5MPa and only the former Ministry of Petroleum has this standard.
Application Of SF440 RST37.2 Carbon Steel Reducing Flange
Carbon steel reducing flange reducing flanges are also called sealing and fastening connectors. Reducing flange are disc-shaped parts, most common in pipeline engineering, and flanges are also used in pairs.In the field of pipeline engineering, flanges play a crucial role in ensuring secure and efficient pipeline connections.
Flanges are installed in various ways in pipelines that need to be connected. They can be used for low-pressure pipelines, and welding flanges are used when the pressure is above 4kg.
Add sealing points between the two flanges and then tighten them with bolts. Flanges with different pressures of course have different thicknesses, and the bolts used are also different. These equipment components are designed with matching flange shapes, commonly referred to as flange connections. It is widely used in large containers in the fields of aerospace, petroleum, and chemical industry.
Advantages Of SF440 RST37.2 Carbon Steel Reducing Flange
SF440 RST37.2 carbon steel reducing flanges have multiple advantages：
A standard reducing flange not only saves space and reduces weight but, more importantly, it ensures that no leakage occurs at the joint. The compact flange’s reduced size is due to the reduced seal’s diameter, which will reduce the cross-section of the sealing surface.
Additionally, a sealing ring has replaced the flange gasket to ensure that the seal face matches perfectly. In this way, only a small amount of pressure is required to compress the cover tightly. With the reduction in the required pressure, the required bolt size and number can be reduced accordingly.
Processing process of Reducing flange
Since the nominal diameter of the container cylinder of the reducing weld neck flange and the specific size indicated by the nominal diameter of the pipe are different, the sizes of the container flange and the pipe flange of the same nominal diameter are also different, and the two cannot be used interchangeably.
Usually, the Reducing flange is divided into several arc segments for processing. First of all, the blank is forged into a square billet and then cold-formed into an arc. After annealing and stress-relieving heat treatment, it is assembled into a complete circle and processed on a vertical lathe to the designed shape and size. Finally, it is transported to the construction site, combining several arcs. Welded into a complete reducing weld neck flange, and then assembled with the pressure vessel.
Reducing flanges has different production standards for use and production. According to the corresponding standards, the actual use value and role of Reducing flange can be guaranteed.
