Specification List

A steel pipe reducer is a component used in the pipelines to reduce its size from large to small bore in accordance to the inner diameter. The length of the reduction here is equal to an average of the smaller and larger pipe diameters. Here, the reducer can be used as a diffuser or a nozzle. The reducer helps in meeting the existing piping of varied sizes or hydraulic flow of the piping systems.

The usage of a steel reducer is carried out in the chemical factories and power plants. It makes the piping system reliable and compact. It safeguards the piping system from any kind of adverse impact or thermal deformation. When it is on the pressure circle, it prevents from any type of leakage and is easy to install. The nickel or chrome coated reducers extends the product life, useful for high vapor lines, and prevents corrosion.

Reducer Types

There are two types of reducer, concentric reducer and eccentric reducer.

Concentric Reducer

This reducer consists of the symmetrical and conical shaped fittings that enlarge or reduce the diameter equally about the center line. For an example, when 1” pipe transitions to ¾” pipe, then the top or bottom of the pipe do not remain level. It is widely used when single or multiple diameter changes.

Eccentric Reducer

A conically shaped fitting that reduces or enlarges the diameter, but it is not symmetrical about the center line. This is used in pipe-work systems for reducing the diameter of a pipe from one size to larger or small size.

Ranges from different connection types, pipe reducer could be classified with socket weld reducer and butt weld reducer.

Socket weld reducer also called socket weld insert, it has three types 1, 2 and 3. Manufacturing standards comply to ASME B16.11.

The Socket Weld resists ½ of the strength of butt welding, so it is used for small-diameter pipes possessing a diameter of NPS 2 or less. Butt Weld has good strength, as it is suitable for high pressure and temperature pipelines.

Butt weld reducer ends in plan or beveled, manufactured in accordance with ASME B16.9 and welding process according ASME B16.25.

Product Description

The reducer is a pipe fitting used for the diameter of the pipe. The commonly used forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for reducing diameter pipes of certain specifications.

a. Diameter reduction/diameter expansion forming

The diameter reduction forming process of the small and small heads is to put a tube blank with the same diameter as the large end of the small and small heads into a forming die, and press the tube in the axial direction to make the metal move along the mold cavity and shrink into shape. According to the size of the reduced diameter of the reducer, it is divided into one-time press forming or multiple press forming.

b. Stamping and forming

In addition to the use of steel pipes as raw materials to produce the small and small heads, some specifications of the small and small heads can also be produced by the stamping process of steel plates. The shape of the punch used for drawing is designed with reference to the size of the inner surface of the size head, and the blanked steel plate is punched and stretched with the punch.
