Product Introduction
GOST Flange Manufacturer & Supplier | Carbon Steel & Stainless Steel GOST Flanges
Hebei Jinsheng Pipe Fitting Manufacturing specializes in creating premium GOST flange arrangements for over 40 a long time. Our metric-standard flanges cover weight appraisals from PN6 to PN100, with total measure accessibility from DN10 to DN2000. Working from our 7,000+ square meter office, we convey remarkable quality with month to month shipments surpassing 50 holders. Our progressed fabricating capabilities guarantee exact GOST 12820, 12821, and 33259 compliance, serving vitality framework ventures over Russia and CIS locales with demonstrated reliability.
GOST Flange Overview
The products speak to the foundation of metric channeling frameworks all through Russia, CIS countries, and Eastern European markets. These precision-engineered components take after strict Russian benchmarks for pipeline associations in oil, gas, petrochemical, and area warming applications.
Our fabricating prepare consolidates progressed metallurgy and quality control frameworks. Each flange experiences thorough testing to guarantee compatibility with metric steel channels and resistance to extraordinary temperature varieties common in these topographical regions.
Key Features & Advantages

Manufacturing Process
Our generation starts with certified crude materials from affirmed providers. Hot manufacturing shapes the essential spine geometry, taken after by accuracy machining for dimensional accuracy.
Heat treatment normalizes fabric properties for ideal execution in benefit conditions. Computer-controlled machining centers guarantee steady confronting geometry and jolt gap situating. Last review incorporates dimensional confirmation and surface wrap up measurement.
Surface Finish & Coating Options
Standard wraps up incorporate smooth machined surfaces with 125-250 μin Ra determination. Discretionary coatings include:
- Hot-dip galvanizing for erosion protection
- Epoxy powder coating for chemical resistance
- Anti-rust oil treatment for capacity protection
- Special coatings for particular natural conditions
Applications
Oil & Gas Foundation: Pipeline associations in extraction, refining, and dispersion frameworks all through Russia and neighboring countries.
District Warming Systems: Civil warming frameworks requiring dependable associations for hot water and steam distribution.
Petrochemical Plants: Handle channeling frameworks dealing with different chemicals and hydrocarbons beneath controlled conditions.
Power Generation: Steam and cooling water frameworks in warm control plants over the region.
Industrial Fabricating: Chemical preparing, steel generation, and other overwhelming businesses requiring strong channeling connections.
Packaging & Delivery
GOST flange get person security through plastic caps and wrapping materials. Wooden cases or steel outlines give shipping security for bigger quantities.
Export bundling incorporates dampness security and stun retention materials. Documentation incorporates process test certificates, dimensional reports, and fabric traceability records. Conveyance regularly happens inside 25-35 days depending on arrange specifications.
Customization Service
We give custom fitted arrangements for particular venture necessities. Custom measurements, extraordinary materials, and special confronting arrangements are accessible upon request.
Engineering bolster incorporates specialized interview and compatibility confirmation. Our group works straightforwardly with venture engineers to guarantee ideal spine determination for particular applications and working conditions.
Quality Control
Every flange experiences comprehensive assessment counting dimensional estimation, fabric confirmation, and surface wrap up evaluation. Non-destructive testing affirms basic keenness when required.
Pressure testing approves fixing execution beneath indicated working conditions. Last assessment guarantees total compliance with pertinent GOST guidelines some time recently bundling and shipment.
FAQ
Q: Why does a product have different "Executions"?
A: Executions refer to flange face configurations. Execution 1 features standard raised faces, while Execution 2 and 3 involve specialized groove or recessed designs for enhanced sealing in high-pressure applications.
Q: Can flanges connect to ANSI standard pipes?
A: Direct connection isn't recommended due to different bolt patterns and dimensions. Transition flanges or adapters are necessary for such connections.
Q: What's the maximum temperature rating for flanges?
A: Temperature ratings depend on material grade and pressure class, typically ranging from -40°C to +450°C for standard carbon steel grades.
