GOST Standard Butt-Weld Fittings are high-quality, durable piping components manufactured in strict accordance with Russian and CIS technical standards. Designed to create strong, leak-proof, and permanent connections, these fittings include Elbows, Tees, Reducers (Concentric and Eccentric), and Caps. Shanxi Xinshunda Flange Manufacturing Co., Ltd. specializes in producing GOST-compliant fittings using premium-grade carbon, alloy, and stainless steels. Our advanced hot-forming and welding technologies ensure exceptional dimensional accuracy and structural integrity, making our fittings the preferred choice for heavy-duty industrial applications in Russia, Eastern Europe, and former Soviet republics. Full compliance with GOST standards and comprehensive material traceability are guaranteed.
Production Details
Our ASTM A193 bolts are produced using state-of-the-art CNC machinery to ensure every thread and hexagonal head meets precise engineering drawings. The raw materials undergo strict chemical composition analysis before entering the production line. Each fastener is subjected to rigorous surface inspection to ensure the absence of defects such as cracks, laps, or improper coating. The dimensional accuracy is verified using advanced measuring instruments, ensuring a perfect match with your mating flanges.
Product Properties and Application
Product Properties
Strict GOST Compliance: Manufactured exactly to Russian state standards, ensuring perfect interchangeability and compatibility with existing GOST piping systems.
High Pressure & Temperature Resistance: Engineered to withstand extreme operational conditions, including high-pressure steam, oil, and gas pipelines.
Superior Weldability: The precisely machined beveled ends allow for full-penetration welding, creating a monolithic joint that is as strong as the pipe itself.
Excellent Corrosion Resistance: Available in a variety of corrosion-resistant alloys and stainless steels, suitable for aggressive chemical environments.
Application
GOST Standard Butt-Weld Fittings are extensively used in regions and industries that adhere to Russian technical norms. Key applications include Oil & Gas Exploration and Transport, Thermal and Nuclear Power Plants, Chemical and Petrochemical Processing, and Heavy Machinery. They are also widely utilized in Municipal Water Supply and Heating Networks across Russia, Ukraine, Kazakhstan, and other CIS countries.

QA & QC
At Shanxi Xinshunda, we implement a rigorous Quality Control system tailored for GOST fittings. Every fitting undergoes strict dimensional inspections using calibrated Russian-standard gauges and templates. We perform Hydrostatic or Pneumatic pressure tests to verify leak tightness and structural integrity. Surface defects are checked via Magnetic Particle Inspection (MPI) or Dye Penetrant Testing (DPT). Material composition is verified through spectroscopic analysis, and Mill Test Certificates (EN 10204 3.1 / GOST 2.610) are provided with every shipment.
