DIN Standard Butt-Weld Fittings are precision-engineered piping components manufactured in strict accordance with German and European technical standards. Designed to provide robust, leak-proof, and permanent connections, this comprehensive range includes Elbows, Tees, Reducers (Concentric and Eccentric), and Caps. Shanxi Xinshunda Flange Manufacturing Co., Ltd. specializes in producing DIN-compliant fittings using premium-grade carbon, stainless, and alloy steels. Our advanced hot-forming and cold-extrusion technologies ensure exceptional dimensional accuracy and structural integrity, making our fittings the preferred choice for high-demand industrial applications across Europe, Asia, and global markets. Full compliance with DIN 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 DIN Compliance: Manufactured exactly to German industrial standards, ensuring perfect interchangeability and compatibility with existing DIN piping systems.
High Structural Integrity: Engineered to withstand extreme operational conditions, including high-pressure steam, corrosive chemicals, and cryogenic temperatures.
Superior Weldability: The precisely machined beveled ends allow for full-penetration welding, creating a monolithic joint that is as strong as the pipe itself.
Optimal Flow Dynamics: Featuring smooth internal bores and precise curvature radii, these fittings minimize flow resistance, turbulence, and pressure drop.
Application
DIN Standard Butt-Weld Fittings are extensively used in industries that demand high precision and reliability. Key applications include Chemical and Petrochemical Processing, Pharmaceutical and Food Processing (using stainless steel grades), Power Generation Plants, and HVAC Systems. They are also widely utilized in Municipal Water Supply and Treatment networks, as well as Pulp and Paper Manufacturing across Europe, the Middle East, and global markets.

QA & QC
At Shanxi Xinshunda, we implement a rigorous Quality Control system tailored for DIN fittings. Every fitting undergoes strict dimensional inspections using calibrated German-standard gauges and templates to ensure adherence to DIN tolerances. 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) are provided with every shipment.
Packing, Storage, Handling and Transportation
To protect the product during transit, each fitting is carefully cleaned and the beveled ends are coated with rust-preventative oil. Smaller fittings are individually wrapped in plastic bags or bubble wrap, while larger components are stacked and securely fixed on strong plywood pallets. For international shipping, products are packed in sturdy plywood cases with ample cushioning to prevent movement and surface damage. Each package is clearly labeled with the size, material, quantity, and batch number. Store in a dry, well-ventilated area to prevent corrosion.
