Steel Reducers – Concentric & Eccentric Pipe Fittings | PS Steel Supplier

Pipe fittings play a vital role in the steel industry. Whenever two different sized pipes need to be connected, a steel reducer is used. It is a special type of pipe fitting designed to move the flow of liquid or gas from a larger pipe to a smaller pipe in a balanced and safe manner.

In this video, we will discuss in detail – what are steel reducers, their types, materials, standards, applications, dimensions, manufacturing process, installation guide, price factor, and why PS Steel Supplier is the best choice for you.

What are Steel Reducers?

Definition and Purpose

The main purpose of a steel reducer is to change the diameter of a pipe from a larger size to a smaller size. It controls the direction, pressure and speed of flow in a piping system.

Working method in piping system

When a liquid or gas has to be sent from a larger pipe to a smaller pipe in a system, direct connection is not possible. Here the steel reducer makes the flow smooth and reduces pressure loss.

Types of Steel Reducers

Concentric Reducer

Features and Applications

Connects both pipes on the same centerline.

Flow remains balanced and uniform.

It is used on vertical piping systems and pump outlets.

Dimensional Specifications

• Size Range: ½” to 48” NB
• Thickness: SCH 10 to SCH 20

Eccentric Reducer

• Offset Design Benefits
• Its lower side remains flat.
• Prevents gas pocket formation.
• Suitable for horizontal piping systems.

Installation Guidelines

It is most beneficial to install the pump on the suction side.

Swage Reducer

• Small size applications
• Used in small pipe connections, instrumentation and control piping.

Steel Reducer Materials

• Stainless Steel Reducers (SS 304, 316, 321)
• Corrosion-resistant and suitable in food, pharma, marine industries.
• Carbon Steel Reducers (A234 WPB)
• Economical and robust, most commonly used in oil and gas pipelines.
• Alloy Steel Reducers (WP5, WP9, WP11)
• For high-temperature and high-pressure applications.
