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

Steel Material Seamless Concentric Reducer Din2616 Jis B2311 0

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.
