C22.8 Carbon Steel Reducing Flange

Elite Piping Manufacture produces high-quality C22.8 carbon steel reducing flanges with reliable quality and excellent performance. These flanges are used in place of standard flanges to allow for changes in pipe size and eliminate the need for a standard reducer in the pipe.

The flange consists of one specified diameter and a smaller bore diameter.
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 converting pipe sizes.

Discover a variety of flanges, including weld neck, slip-on, and threaded end types. Reducing flange is an economical way to transition between different pipe sizes but is rarely used in piping due to the large pressure loss.

Product Features Of C22.8 Carbon Steel Reducing Flange

Anti-corrosion, acid and alkali resistance, long service life, reasonable price calculation, smooth surface, acid and alkali resistance, high-temperature resistance, beautiful appearance, and strong texture performance.

Connection Methods Of C22.8 Carbon Steel Reducing Flange

Reducing flanges are usually connected by flange nuts and bolts.
Professional integral forging, forging manufacturing, middle plate cutting, middle plate rolling, etc.

Purpose Of C22.8 Carbon Steel Reducing Flange

Reducing flanges is widely used in water conservancy, electricity, power stations, pipeline accessories, industry, pressure vessels, etc.

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. Still, 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, the installation size does not allow the installation of a reducer or it is unreasonable to install several reducers.

At present, reducing flanges is limited to PN ≤ 2.5MPa, and only the former Ministry of Petroleum has this standard.

Application Of C22.8 Carbon Steel Reducing Flange

Reducing  flanges, called sealing and fastening connectors, are disc-shaped parts most commonly used in pipeline engineering. They are also used in pairs. Flanges are crucial in ensuring secure and efficient pipeline connections in this field.
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 have different thicknesses, and the bolts used differ.

These equipment components are designed with matching flange shapes, commonly called flange connections. They are widely used in large containers in the aerospace, petroleum, and chemical industries.

Advantages Of C22.8 Carbon Steel Reducing Flange

Reducing flanges offers multiple advantages: they save space, reduce weight, and, most importantly, prevent leakage at the joint. By reducing the diameter of the seal, the compact flange diminishes the cross-section of the sealing surface.

Additionally, replacing the flange gasket with a sealing ring ensures a better matching of the sealing faces. 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 C22.8 Carbon Steel Reducing Flange

Since the nominal diameter of the container cylinder of the reducing 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, 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 completely reduced flange, it is assembled with the pressure vessel.
Reducing flanges has different production standards for use and production. According to the corresponding standards, the use value and role of reducing flange can be guaranteed.
