Concentric reducers

Concentric reducers feature a symmetrical conical structure, with both ends and the midpoint located on the same centerline. They are suitable for connecting vertical pipes of varying diameters or for systems where horizontal alignment is not necessary.

The smooth transition of fluid along the tapered channel effectively reduces turbulence and pressure drop, making them suitable for applications such as chemical, oil and gas, and water treatment, where center alignment and uniform flow rates are crucial. Their manufacturing process is relatively simple and cost-effective.

Specifications: From ¾×½” to 48×40″, complying with ASME B16.9’s maximum NPS48 range.
Wall Thickness Range: Wall thickness data is derived from the ASME B36.10/B36.19 Schedule comparison table, covering Schedules 5S, 10S, 10, 20, 30, 40S/Std, 60, 80S/XS, 100, 120, 140, and 160, for a total of 13 grades.
Applicable Standards: ASME B16.9 and MSS-SP-75 for Butt-weld concentric reducers. Common materials include ASTM A234 (carbon steel), A403 (stainless steel), and alloy steel.
Production Process: Small and medium sizes are typically hot forged, spun, or die-forged; large sizes or thick walls may be roll-welded; thick walls/high-pressure reducers require post-weld heat treatment (PWHT).

eccentric reducer

Eccentric reducer has one flat side and one tapered side, with misaligned centerlines. It can be installed with the flat side facing up or down to prevent liquid or air accumulation. With the flat side facing up, it’s ideal for horizontal liquid flow, preventing air pockets at the top of the pipe. With the flat side facing down, it’s suitable for steam or aerated systems, facilitating drainage and supporting pipe racks.

Eccentric reducers are suitable for pump inlets and horizontal pipelines, stabilizing suction performance and preventing cavitation. However, due to their slightly more complex manufacturing and strict installation orientation requirements, they are slightly more expensive than concentric reducers.

Classified by Connection Types

As per the connection mode, Pipe Reducer could be classified by Butt Weld, Socket Weld and Threaded.

Butt-weld Reducer

Description	A forged or formed conical or eccentric pipe fitting designed for connecting pipes of different diameters via full penetration butt weld. It provides a smooth, continuous metal path across the transition.
Features	Welded joint offers high strength and excellent leak integrity Smooth internal flow surface with gradual bore reduction, minimizing pressure drop and turbulence Compatible with high-pressure, high-temperature systems Lower overall cost relative to socket/threaded options once installed
Applications	Widely used in chemical, petrochemical, oil & gas pipelines, power plants, refineries, water treatment, cryogenic systems, and other industrial fluid transport systems requiring robust transitions

Socket Weld Pipe Reducer

Description	Reducer in which the pipe is inserted into a recessed “socket” in the fitting and joined with a fillet weld. Often available in forged socket-weld reducing bushings or inserts for standard socket fittings.
Features	Easier to align and install for small-diameter systems (typically NPS ≤ 4) Strong structural integrity via fillet welds Simplified production and assembly—no beveling required on pipe ends However, potential for crevice corrosion or buildup in the socket area
Applications	Ideal for small lines conveying toxic, flammable, or expensive fluids where leak integrity is crucial. Common in oil & gas, petrochemical, power generation, and industrial piping systems.

Threaded Pipe Reducer

Description	Threaded reducing fitting (usually forged) that screws onto smaller/larger pipe diameters. It enables size transitions without welding, using tapered or straight threads like NPT, BSP, etc.
Features	No welding required; suitable for assembly and maintenance in the field Quick to install, easy to disassemble or replace Best suited for low/medium-pressure and small-diameter lines Threaded joints may not offer as tight a seal as welded connections and can be susceptible to leakage or corrosion over time
Applications	Common in plumbing, low-pressure process lines, sprinkler systems, natural gas distribution, instrumentation, and connection to vessels or small equipment.

FAQs About Pipe Reducer

Reducers are primarily used to connect two pipes of different diameters, ensuring a smooth transition between pipe systems, ensuring stable flow of fluids (liquids, gases, etc.) during transportation, and reducing resistance and eddy currents caused by changes in pipe diameter.

Common types include concentric reducers and eccentric reducers. Concentric reducers have their ends aligned on the same axis and are suitable for general pipe connections. Eccentric reducers have their ends aligned on different lines, which prevents air or liquid resistance in the pipe and are often used in special applications such as pump inlets.

Common materials include carbon steel, stainless steel, and alloy steel. Carbon steel is suitable for general neutral media and low-pressure applications; stainless steel is highly corrosion-resistant and suitable for corrosive media or applications with high hygiene requirements; alloy steel is suitable for high-temperature and high-pressure environments.

They are generally expressed using the nominal diameters of both ends. For example, DN100×80 indicates a nominal diameter of 100mm on one end and 80mm on the other. Parameters such as wall thickness are sometimes also indicated.

Structurally, the centers of the two ends of a concentric reducer are coaxial, while the centers of the two ends of an eccentric reducer are not coaxial. In terms of application, concentric reducers are used for general piping transitions, while eccentric reducers are used where air and liquid resistance must be avoided, such as at the suction end of a pump, to prevent air accumulation.

Pressure ratings correspond to piping standards. ASME standards include Class 150 and Class 300. When selecting a reducer, consider the operating pressure of the piping system to ensure the pressure rating of the reducer is not lower than the system’s operating pressure.

The main options are welding, threading, and flange connections. Welding is suitable for high-pressure, large-diameter pipes and provides a secure connection; threading is suitable for low-pressure, small-diameter pipes and is easy to install; and flange connections are suitable for pipe systems that require frequent disassembly.

Wall thickness should be determined according to relevant standards based on factors such as the pipe’s operating pressure, media characteristics, and pipe diameter. Sufficient wall thickness ensures the reducer’s strength and pressure resistance. Insufficient wall thickness may cause the pipe fitting to crack, compromising safety.

Depending on the material, they can be used with a variety of media, including water, steam, oil, natural gas, corrosive liquids (such as acid and alkaline solutions), and food and beverages. When selecting a reducer, it’s important to match the media’s characteristics. For example, corrosive media require corrosion-resistant materials such as stainless steel.

Service life varies depending on the material, operating environment, and media characteristics, but generally ranges from several years to several decades. Factors affecting pipe life include the corrosiveness of the medium, temperature and pressure levels, and proper installation and maintenance. Highly corrosive environments, high temperatures, and high pressures can shorten the pipe’s service life.

Choose a reducer with a thicker wall and higher material strength, and use ribbed reinforcement if necessary. Ensure the connection is secure during installation, and use elastic sealing elements to reduce the impact of vibration on the reducer.

They do require regular maintenance. Maintenance includes inspecting the reducer surface for corrosion, cracks, leaks, loose connections, and seal integrity. Any problems identified should be repaired or replaced promptly to avoid impacting the operation of the piping system.

Price is affected by factors such as the material (for example, stainless steel is more expensive than carbon steel), the size (larger diameters and special specifications are more expensive), the production process (custom products are more expensive than standard products), and the quantity (bulk purchases are relatively cheaper).

Factors to consider include the nominal diameter of the pipe (determine the dimensions at both ends), operating pressure (match the pressure rating), media type (choose the appropriate corrosion-resistant material), temperature (high temperatures require high-temperature-resistant materials), and the installation environment (such as vibration and frequent disassembly).

Common problems include leakage, rupture, and severe corrosion. In case of leakage, inspect the sealing surfaces or welds and replace the seals or re-weld. In case of rupture or severe corrosion, replace the reducer with one of the same specifications and material. Before replacement, shut down the relevant piping system to ensure safety.
