1. Product Description
A Reducing Coupling is a specialized pipe fitting designed to connect two pipes of different diameters in a pipeline system. The eccentric design ensures a smooth transition between the pipes while maintaining structural integrity and flow efficiency. It is widely used in industries requiring precise alignment adjustments, such as oil and gas, chemical processing, and water treatment.
2. Key Features
- Eccentric Configuration: Offsets the centerline of the larger and smaller pipes to prevent fluid accumulation (ideal for horizontal pipelines).
- Socket Welding Connection: Ensures leak-proof joints with high-pressure resistance.
- Material Durability: Typically made from carbon steel, stainless steel, or alloy steel for corrosion resistance and mechanical strength.
- Compact Design: Reduces space requirements compared to flanged reducers.
