Detailed Introduction
A reducer is a conical pipe fitting that changes the flow cross-section in a piping system. Its main function is to regulate the medium flow velocity and pipeline pressure drop, and to reduce turbulence and eddy current impact. We provide two structures: concentric and eccentric. Concentric reducers are mostly used for vertical pipelines, instrument pipelines, and steam lines, while eccentric reducers are mostly used for horizontal pipelines and pump inlet pipelines. Products can be produced according to standards such as the national standard GB/T12459, GB/T13401, the American standard ASME B16.9, as well as petrochemical SH, chemical HG, Japanese standard JIS, German standard DIN, and others, and support seamless stamping, rolled welding, and forged forming. Conventional specifications are sufficiently available in stock, support a minimum order of 1 piece, and can also be customized according to drawings or samples for non-standard diameters, special wall thicknesses, and anti-corrosion treatment.
- Concentric and eccentric structures are available. Eccentric reducers can be customized with flat top or flat bottom, adapting to pump inlet anti-cavitation and pipeline drainage anti-liquid accumulation working conditions.
- Adopting seamless stamping, precision welding, and large-diameter rolling processes, the pipe wall thickness is uniform, the inner and outer surfaces are smooth, with no pores, sand holes, or cracks
- Supports standards such as Chinese GB, American ASME, Japanese JIS, German DIN, etc., and can match imported equipment and foreign-related projects
- Regular standard in-stock specifications support a minimum order of 1 piece, suitable for sample submission for inspection, engineering material replenishment, and sporadic repairs

| Packaging | Our factory's reducers adopt a professional export-grade packaging process, safeguarding product transportation safety throughout, and adapting to domestic logistics as well as international sea and air long-distance transportation needs. All pipe fittings are uniformly wiped and cleaned before leaving the factory, and anti-rust oil is evenly applied to the surface, effectively preventing oxidation, rusting, and corrosion during transportation. Small-diameter reducers use independent dust-proof protective caps to seal the pipe openings, preventing debris from entering the interior of the pipeline and scratching the bevel; for medium and large diameter products, all ports are sealed and protected, preventing collision deformation and end face damage. Conventional specifications use thickened woven bags and hard cardboard boxes for layered packaging; large-volume bulky items and large-diameter products use solid wood pallets for fixed packing, tightly bound with even force distribution, preventing displacement and wear caused by transportation bumps. All packaging is moisture-proof, dust-proof, rust-proof, and compression-resistant, fearless of rainy weather, humid... |

Overview
A reducer is a conical pipe fitting used in piping systems to connect two sections of pipe with different nominal diameters. Its function is to change the flow cross-section, regulate medium flow velocity and pressure drop, and reduce turbulence and eddy current impact. The reducers we produce are divided into two structures: concentric and eccentric. Concentric reducers are mostly used for vertical pipelines, instrument piping, and steam lines, while eccentric reducers are mostly used for horizontal pipelines and pump inlet lines. The products are matched with elbows, tees, and flanges to form process piping, and are commonly used for reducing connections at the inlet and outlet of pumps, heat exchangers, and tanks.
Key Features
We use seamless stamping, precision welding, and large-diameter rolling processes to produce reducers. The pipe wall thickness is uniform, the inner and outer surfaces are smooth, and there are no pores, sand holes, or cracks, which helps avoid medium scaling and blockage. The two structures, concentric and eccentric, can adapt to different installation conditions. The reducing transition is smooth and can stably regulate fluid flow velocity and pipeline pressure. The products support standards such as national standard GB, American standard ASME, Japanese standard JIS, and German standard DIN, and can match imported equipment and foreign-related projects. Non-standard diameters, special wall thicknesses, special lengths, and special anti-corrosion treatments can all be customized according to drawings or samples.
Applications
Reducers are used in industrial piping systems such as petroleum refining, fine chemicals, thermal power generation, thermal power heating, natural gas transportation, and coal chemical industry, and are also used in municipal engineering such as urban water supply, sewage discharge, heating networks, gas pipelines, and fire protection networks. In terms of equipment matching, they are commonly used for reducing connections at the inlet and outlet of water pump units, heat exchangers, gas storage tanks, reactors, boilers, and automated fluid equipment. In addition, they are also used in mining pipelines, oilfield pipelines, ship pipelines, and plant circulating water pipelines. For construction environments such as indoor and outdoor, buried, and overhead, suitable solutions can be confirmed according to project requirements.
Specifications
Reducers can be produced according to standards such as national standard GB/T12459, GB/T13401, American standard ASME B16.9, petrochemical SH, chemical HG, Japanese standard JIS, and German standard DIN. Forming processes include seamless stamping, rolled welding, and forging. Materials can be selected from carbon steel, stainless steel, alloy steel, duplex steel, special heat-resistant steel, etc. We support customization of non-standard diameters, unconventional reduction ratios, special long and short tapers, and thickened wall thicknesses, and can also customize top-flat or bottom-flat eccentric structures, special bevel forms, and integrated flange reducers. Surface treatment options include hot-dip galvanizing, cold galvanizing, sandblasting and rust removal, anti-corrosion paint, and plastic-lined anti-corrosion. Please contact us to confirm specific specifications and parameters.
