GOST 17375-2001 Steel 20 90° Long Radius Elbow for Latvia Piping Project
Haihao Group has finished production, full inspection and shipment of GOST 17375-2001 Steel 20 90° long radius elbow for our Latvia client. This 273.0 × 10.0 mm elbow is formed to 1.5D bending radius (R=375 mm), built for butt-weld connection on industrial piping systems following Russian GOST specification.
This GOST 17375-2001 Steel 20 90° long radius elbow follows tight forming and machining controls defined in the client technical sheet. The extrados wall thickness is maintained at a minimum of 87.5% of nominal thickness, a critical control point to avoid excessive thinning after hot forming. The pipe end preparation is machined precisely: bevel angle set at 30° ±3°, with root face c = 1 mm ±0.5 mm, ready for consistent field welding.
Material compliance for this GOST 17375-2001 Steel 20 90° long radius elbow is strictly verified by heat analysis. The Steel 20 carbon steel meets fixed chemical limits: C 0.17–0.24%, Mn 0.35–0.65%, Si 0.17–0.37%, P ≤0.03%, S ≤0.035%, Cr, Cu and Ni each limited below 0.3%. This grade delivers good ductility and weldability widely adopted for water, steam and general process pipelines across Baltic region installations.

Every GOST 17375-2001 Steel 20 90° long radius elbow undergoes a complete test package: mechanical property verification, hydrostatic pressure test, plus 100% ultrasonic examination before release. All test certificates, heat reports and UT records are bundled together, which simplifies document review for Latvian engineering teams used to GOST-based piping components.
Baltic market buyers often struggle to locate reliable fabricators who can supply GOST 17375 elbows with both controlled bevel geometry and full traceable test documentation, not just standard size products. Haihao Group keeps stable manufacturing capability for GOST carbon steel elbows and fittings, supporting custom dimensional and inspection add-ons.
If your project requires GOST 17375-2001 Steel 20 90° long radius elbow or other GOST piping fittings with defined end bevel and NDE requirements, send over your specification for a formal quotation with complete material and test documentation.
