Product Description

Reducer

Reducer (also known as concentric or eccentric reducer) is a pipe fitting used to connect two pipes of different diameters.
Classification:

By Shape:
Concentric Reducer: The centerlines of both ends align, ideal for smooth fluid transition in systems without directional constraints.
Eccentric Reducer: One side is flat, with offset centerlines. Commonly used to prevent gas accumulation (e.g., liquid pipelines) or liquid pooling (e.g., gas pipelines).
By Manufacturing Process:
Seamless Reducer: High strength and leak resistance, suitable for high-pressure or corrosive environments.
Welded Reducer: Cost-effective, fabricated via welding, used in low-pressure systems for general media transfer.

Applications:

Petrochemical Industry: Connects reactors, heat exchangers, and pumps with varying pipe sizes to meet process requirements for flow and pressure.
Power Generation: Enables diameter transitions in steam, water, and cooling systems to ensure operational stability.
Construction: Adjusts pipe diameters in water supply/drainage and fire protection systems to optimize flow distribution across buildings.

Product Description

1. Concentric Reducer

Feature: The centerlines of both ends are aligned, forming a symmetrical cone shape with uniform diameter transition.
Application Scenarios:Ideal for pipelines without directional constraints, such as vertical pipes or horizontal pipes where fluid flow direction is unrestricted.
Commonly used in scenarios requiring smooth diameter changes to minimize fluid resistance (e.g., pump inlets/outlets, heat exchanger connections).
Advantages: Provides smooth fluid flow with minimal pressure loss.

2. Eccentric Reducer

Feature: The centerlines of both ends are offset, with one side flattened (either the bottom or top edge is straight), creating an asymmetrical cone shape.
Application Scenarios:
Flat on Bottom: Used in horizontal pipelines for liquid media to prevent gas accumulation at the top (e.g., condensate lines, centrifugal pump inlets).
Flat on Top: Used in horizontal pipelines for gas media to avoid liquid pooling at the bottom (e.g., steam lines, compressed air pipelines).
Advantages: Prevents gas/liquid retention, suitable for directional flow requirements.
