Concentric Reducer

Concentric reducer, also known as concentric reducing pipe, is a common pipe fitting in piping systems. Its two ends share the same central axis, mainly used for pipe diameter reduction, pressure buffering and medium flow regulation.

It is manufactured by seamless pressing, stamping and welding processes. Available in carbon steel, stainless steel, alloy steel and other materials, complying with GB/T, ASME, DIN and other international standards. Featuring complete specifications, uniform wall thickness, good sealing performance, high pressure resistance and corrosion resistance.

Widely applied in petroleum, chemical, power supply, water supply and drainage, natural gas and sewage treatment industries. It connects pipes of different diameters in straight pipelines, realizes smooth flow transition without eccentric flow, and is an essential reducing fitting for pipeline engineering.

Key Functions

Connect Different Pipe Sizes

Join pipes of different diameters with concentric, symmetrical transition; no flow offset, minimal turbulence.

Smooth Flow & Reduce Pressure Loss

Tapered design lowers flow resistance, eddies and pressure drop; saves energy, stabilizes flow.

Control Flow Velocity & Pressure

Adjust flow rate and system pressure via diameter ratio to meet process requirements.

Protect Pumps & Equipment

Installed at pump suction/discharge (vertical preferred); prevents cavitation, protects impellers.

Instrument & Valve Adaptation

Matches connection sizes for flowmeters, control valves and flanges; ensures accurate measurement.

Ideal for Vertical/High-Pressure/Gas Lines

Best for vertical pipes, high-pressure steam, gas and clean liquid lines; no gas/liquid accumulation, uniform stress.
