CONCENTRATED PIPES

1. Product Overview

A concentric reducer (also called a concentric pipe reducer) is a truncated cone-shaped fitting used to connect two pipelines of different diameters so that their centerlines remain aligned. This is the standard solution for increasing or decreasing flow velocity in a system.

3. Key Features and Main Functions

• Pressure balancing: The cone design allows fluid to transition smoothly from larger to smaller pipes (or vice versa), minimizing sudden pressure fluctuations.
• Structural strength: With perfect symmetry along the centerline, concentric reducers distribute forces and vibrations evenly, making them more robust than eccentric types.
• Aesthetic symmetry: Creates a balanced pipeline layout, making it easier to install supports since the pipe centerline remains unchanged.

4. When to Use Concentric Reducers

Customers should note the correct installation positions:

• Vertical pipelines: Ideal placement. Fuel flowing up or down through a concentric reducer will not trap air or liquid.
• Horizontal pipelines (not at pump suction): Used in intermediate sections to increase pressure or reduce flow before entering equipment.
• Before and after valves: Applied to reduce pipe size to match valve dimensions (e.g., a 90 mm pipe reduced to fit a 60 mm valve).

5. Key Advantages

• Cost-effective: Generally cheaper and more readily available than eccentric reducers.
• Stable flow: Produces less turbulence, protecting internal pipe linings (if present).
• Standard weld joints: Both ends are beveled, allowing welders to make strong butt-weld connections quickly and securely.
