Shanxi Xinshunda Flange Manufacturing Co., Ltd. delivers high-performance DIN 6 bar flange solutions designed for low-pressure industrial pipeline systems. Our precision-engineered components ensure leak-proof connections and long-term reliability across European standard and global infrastructure projects. With nearly two decades of manufacturing excellence, we serve as a trusted partner for water treatment, HVAC, construction, chemical, and general industrial sectors worldwide.
Advanced Engineering and Material Excellence
Our DIN 6 bar (PN6) flange product line features superior metallurgical properties tailored for low-pressure applications. Manufactured from premium carbon steel (C22.8, A105, RSt37-2), stainless steel (1.4301/304, 1.4401/316), and alloy steel, each component undergoes rigorous heat treatment and CNC machining processes. The 6 bar rating provides optimal performance at temperatures ranging from -20 °C to 300 °C, with stable pressure capabilities under standard working conditions.
Key technical specifications include:
- Strict adherence to DIN 2573, DIN 2576, DIN 2631, DIN 2632 and EN 1092-1 standards
- Available sizes from DN10 to DN2000 nominal diameter
- Multiple face configurations: Raised Face (RF), Flat Face (FF), Tongue and Groove (TG)
- Surface finish quality between 125-250 µin Ra for optimal gasket sealing
- Full traceability with EN 10204 3.1 Material Test Certificates
- Rated pressure: 6 bar (0.6 MPa)
Versatile Industrial Applications
The DIN 6 bar flange serves critical roles in diverse low-pressure operational environments. Municipal water supply and drainage systems rely on our components for secure pipeline joints, while HVAC and heating systems utilize their stable performance for fluid circulation. Chemical processing plants use corrosion-resistant variants for mild media handling, and construction projects depend on their durability for utility networks. Additional applications span fire protection, irrigation, marine engineering, food processing, pharmaceutical facilities, and general machinery where European standard connections are required.
Comprehensive Quality Assurance Protocol
At Shanxi Xinshunda, every DIN 6 bar flange passes through a multi-stage quality verification process. Raw materials receive mill certification and spectral inspection before production begins. Dimensional accuracy is verified using coordinate measuring machines, while visual inspections detect surface imperfections. Hydrostatic testing validates pressure integrity according to European and international standards. Our ISO 9001-certified facility maintains documented procedures for continuous improvement, ensuring consistent compliance with global specifications. Third-party inspection services from SGS, BV, or TUV are available upon customer request.
Professional Packaging and Global Logistics
We protect each DIN 6 bar flange with anti-corrosive oil coating and individual wrapping before securing them in export-grade wooden crates, iron boxes or pallets. Clear labeling includes heat numbers, size ratings, material grades, standards and batch identifiers for complete traceability. Documentation packages contain commercial invoices, packing lists, certificates of origin, and material test reports. Our logistics network facilitates timely delivery to over 70 countries, with customized shipping solutions for urgent project requirements.
Technical Support and Customization Services
Our engineering team provides specialized consultation for DIN 6 bar flange selection based on specific operating conditions. We offer custom manufacturing for non-standard dimensions, special alloy compositions, or unique face designs. Value-added services include beveling, custom drilling patterns per customer drawings, and application-specific anti-corrosion coatings. Frequently asked questions regarding pressure-temperature derating, material compatibility, and installation best practices are addressed through our dedicated technical support channel.
