Seamless Concentric Reducer ASME B16.9 – Low Pressure Loss & Vibration Damping
1. Product Description
A Concentric Reducer is a conical pipe fitting designed to connect two pipes of different diameters. Its main structural feature is that both the larger and smaller ends share the same central axis. This symmetrical structure ensures a steady and smooth transition between different pipe sizes.
These reducers are produced in compliance with international standards including GB/T12459-2005 and ANSI. They are supplied in a variety of materials, such as carbon steel (ASTM A234 WPB), stainless steel (304, 316L), and alloy steel. Typical manufacturing processes include diameter shrinking and stamping forming.
2. Product Applications
Concentric reducers are widely applied in various industries to adjust pipe diameters in fluid transportation systems. Their main role is to achieve a stable flow path transition. Typical application areas include:
Oil & Gas: Crude oil and natural gas pipeline systems.
Chemical Industry: Chemical processing plants and production facilities.
Power Generation: Power stations and related auxiliary systems.
Water & Environmental Engineering: Water supply, drainage, and environmental protection systems such as dust removal.
Other Industries: Shipbuilding, pharmaceutical, food and beverage (dairy, beer, etc.), and other industrial fields.
3. Product Advantages
Smooth Flow & Low Pressure Loss: The symmetrical conical structure enables gradual diameter change, reducing flow resistance, turbulence, and pressure loss in the system.
Avoids Air Trapping: In vertical pipelines, the concentric structure helps prevent the buildup of air bubbles, which is important for keeping the system efficient.
Strong & Leak-Tight Connection: When installed by butt welding, these fittings form a firm, permanent, and uniform joint that can resist high pressure and provide long service life.
