Detailed Introduction

Russian-standard reducers are pipe reducing fittings manufactured in accordance with the GOST 17378-2001 standard. In pipeline systems, they connect pipe sections of different nominal diameters, serving to regulate medium flow velocity, balance pipeline pressure, and reduce fluid turbulence and eddy impact. The products are divided into two categories: concentric reducers (Type K) and eccentric reducers (Type E). The concentric type is used for vertical pipelines, ensuring stable vertical fluid conveyance; the eccentric type is used for horizontal pipelines, avoiding liquid accumulation and gas pockets, and protecting pumps and instruments. Production processes include seamless hot-pressed forming and steel plate rolled and butt-welded fabrication, with conventional and high-pressure versions distinguished by pressure rating. Materials cover Russian-standard-specific grades such as St20 carbon steel, 09G2S low-alloy steel, 12Kh18N10T and 08Kh18N10 stainless steel, and 15Kh5M alloy steel. Nominal diameters range from DN15 to DN800, pressure ratings from PN6 to PN63, with a maximum pressure bearing capacity of 10 MPa. The products mainly target oil and gas extraction, refining and chemical, thermal power stations, municipal heating and water supply, pressure vessels, and ship pipeline projects in the Russian and CIS markets. We can provide Russian-standard material certificates and factory inspection reports, and support non-standard customization.

  • Produced according to GOST 17378-2001 and GOST 17380-2001 standards, with dimensional tolerances, wall thickness, mechanical properties, and non-destructive testing executed according to Russian-standard specifications, and can cooperate with local Russian quality inspection re-inspection and engineering acceptance.
  • Provides two structural types: concentric (Type K) and eccentric (Type E), respectively corresponding to the installation requirements of stable conveyance in vertical pipelines and prevention of liquid accumulation and gas pockets in horizontal pipelines.
  • Materials cover Ст20 carbon steel, 09Г2С low-alloy steel, 12Х18Н10Т and 08Х18Н10 stainless steel, 15Х5М alloy steel, and the corresponding grade can be selected according to working conditions such as low temperature, high temperature, and corrosion.
  • The seamless hot-press forming process is used for integrally formed products, with dense and uniform pipe walls; the steel plate rolling and butt welding process is used for large-diameter specifications. The two processes are matched according to diameter and pressure rating.
  • Nominal diameters cover DN15 to DN800, pressure ratings PN6 to PN63, with a maximum pressure bearing capacity of 10MPa. The corresponding specifications can be confirmed according to project pressure requirements.
  • Supports non-standard dimensions, special wall thickness, non-standard eccentricity, extended end faces, as well as Russian-language laser marking and bilingual packaging customization, processed according to the GOST 17378 standard and provided with customized quality inspection documents.
  • Export packaging is designed according to CIS cross-border transportation requirements, including moisture-proof and shock-proof reinforcement, port dust plugs, fumigated solid wood pallets, and accompanying each batch are Russian-language bilingual certificates of conformity, parameter lists, and material reports.

FAQ

Are the products produced according to Russian GOST 17378 standard?

Our Russian-standard reducers are produced and inspected according to the GOST 17378-2001 standard. Dimensional tolerances, wall thickness, mechanical properties, and non-destructive testing are carried out in accordance with this standard, and we can cooperate with local Russian institutions for re-inspection and engineering acceptance. If you need to view the inspection documents for a specific batch, please contact us to confirm.

Can it be used in extreme cold working conditions such as Siberia?

09Г2С low-alloy steel material can be selected. This grade is supplied according to the low-temperature working condition requirements of the Russian standard, and the applicable lower temperature limit is -70°C. For specific selection, please provide the project's minimum ambient temperature and medium parameters, and we will assist in confirming the material and specifications.

How to choose between concentric reducers and eccentric reducers?

Vertical pipelines generally use concentric reducers to ensure stable vertical fluid transportation; horizontal pipelines generally use eccentric reducers to avoid liquid accumulation, gas accumulation, and gas blockage problems, protecting pumps and instruments. If the pipeline route is complex, please contact us to provide pipeline layout information, and we will assist in confirming.

Do you support small-batch trial orders and non-standard customization?

Conventional standard stock specifications support small trial orders and mixed-batch combined orders. For non-standard customization, we can process concentric and eccentric reducers with non-conventional diameters, special wall thicknesses, non-standard eccentricity, and extended end faces, and can also customize materials such as Ст20, 09Г2С, 15Х5М, 12Х18Н10Т, as well as Russian laser engraving and bilingual packaging. Please provide drawings or dimensional parameters, and we will assist in confirming the solution.
