GOST 17375 Elbow Carbon and alloy steel butt-welding fittings Sharply curved bends type 3D
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.
