Features
- 1. Compliant with multiple high-end international standards including BPE biopharmaceutical, 3A, SMS and DIN BPE. The high-purity pipeline design ensures stable material performance without metal precipitation for strict biopharmaceutical processes.
- 2. The long-radius large-arc structure provides gentler flow transition and greatly reduces pressure loss compared with standard short elbows, effectively protecting material properties and quality.
- 3. Precision forming technology ensures uniform and compact pipe wall without pores or defects, delivering high structural strength and stable performance under long-term high-pressure transportation.
- 4. The ultra-smooth mirror-polished inner wall enables smooth passage of high-viscosity and adhesive media, preventing wall adhesion, caking and deposition to maintain long-term pipeline cleanness.
- 5. Excellent corrosion and high-temperature resistance with stable physical and chemical properties, suitable for long-term continuous fluid transportation in high-end production lines.
- 6. Standardized weld ends precisely match BPE-grade high-end pipelines and sanitary valves, ensuring high-precision pipeline connection and integrated piping performance for automatic precision process systems.
Working Principle
Sanitary 90° Long Weld Elbow adopts butt-weld fixed installation for permanent integration into high-end process pipelines, providing excellent structural integrity and stable sealing performance. With BPE and 3A standard ultra-long arc seamless flow path, it achieves low-loss and stable 90° medium transition. The ultra-gentle bend eliminates turbulence, flow impact and local retention, ensuring stable transportation of high-activity and high-viscosity media. The rigid welded structure prevents loosening and leakage, maintaining long-term high-precision and high-quality pipeline operation for sophisticated hygienic processes.
