OST 17375 Steel Butt-Welding Elbows Manufacturer & Supplier
We are a leading manufacturer and global supplier of GOST 17375 steel butt-welding elbows, serving industries across oil & gas, petrochemical, power generation, shipbuilding, and heavy engineering.
We offer a wide range of GOST standard elbows including 90-degree and 45-degree elbows with seamless or welded construction, conforming to GOST 17375-2001 and earlier Soviet specifications. Our elbows are available in carbon steel, stainless steel, and low-alloy steels depending on your project needs.
Pipe elbows are manufactured in strict accordance with the GOST 17375-2001 standard, ensuring top-quality performance in high-pressure and high-temperature piping systems. These seamless steel elbows are widely used in oil and gas, petrochemical, power generation, and industrial pipeline applications.
The standard applies to seamless welded bends of carbon and low-alloyed steel of type 3D with an R approximately equal to 1.5 DN and angles equal to 45 °, 60 °, 90 ° and 180 °, made of pipes by methods of punching or broaching over a horn-shaped core.
This standard makes reference to GOST 17380–2001. Details of seamless welded carbon and low – alloy steel pipelines. General technical requirements.
Стандарт распространяется на бесшовные приварные отводы из углеродистой и низколегированной стали типа 3D с R приблизительно равным 1,5 DN и углами равными 45°, 60°, 90° и 180°, изготавливаемые из труб методами штамповки или протяжки по рогообразному сердечнику.
