فارسیLeading the Future of Corrosive Fluid Control: Youfumi Lined Valves & Piping Systems
Delivering Zero-Leakage, High-Durability Solutions for the World’s Most Demanding Chemical, New Energy, and Petrochemical Projects.
Proven Success Across Industries
New Energy & Battery Materials
The Challenge: Handling highly pure and corrosive electrolytes and cathode precursors.
Our Solution: Our PFA/PTFE lined systems ensure Zero Metal Contamination and superior chemical stability.
• Key Projects: Lithium battery electrolyte production lines.
• Core Products: Lined Ball Valves, Lined Piping, and specialized sensors for clean-room environments.
| Media | Temperature |
|---|---|
| Acidic, Alkaline, Organic Solvents, Fluoride, High-Purity Gases | -50°C – 260°C |
| Project Location | |
Electrolyte Preparation Systems Battery Material Cleaning and Treatment Processes Hydrometallurgical Processing Gas Control and Distribution Reactors and Chemical Reactors Storage and Distribution Systems | |
Fluoro-Silicon & Fine Chemicals
The Challenge: Managing high-permeation media and extreme temperature fluctuations.
Our Solution: Advanced lining technology that resists blistering and vacuum collapse, engineered specifically for fluoro-silicon monomers and organic silicon processing.
• Key Projects: Large-scale Fluoro-silicon synthesis plants.
• Performance: 3x longer service life compared to standard industrial valves.
| Media | Temperature |
|---|---|
| HF, HCl, H₂SO₄, HNO₃, Fluorosilicic acid, Chlorinated solvents, IPA, acetone, methanol, etc. | –20°C – 180°C |
| Project Location | |
Strong corrosion exists Zero leakage is required High chemical purity must be maintained Frequent on/off operation is needed | |
Ethylene & Large Petrochemical Complexes
The Challenge: Massive scale, high pressure, and the need for strict international compliance (ANSI/DIN/JIS).
Our Solution: Comprehensive fluid control packages for downstream ethylene processing, from large-bore lined butterfly valves to complex piping layouts.
• Key Projects: Integrated Petrochemical Complexes (as seen in our project site photos).
• Safety First: Fire-safe designs and rigorous pressure testing before shipment.
| Media | Temperature |
|---|---|
| NaOH, H₂SO₄, HCl, Demineralized water, Process water, Cooling water with chemical additives | –20°C -150°C |
| Project Location | |
| Electrolyte Preparation Systems Battery Material Cleaning and Treatment Processes Hydrometallurgical Processing Gas Control and Distribution Reactors and Chemical Reactors Storage and Distribution Systems | |
Phosphorus & Heavy Chemical Industry
The Challenge: Dealing with abrasive slurries and strong acids (H2SO4, H3PO4).
Our Solution: Thick-walled PTFE lining and erosion-resistant materials that minimize downtime in heavy-duty chemical production.
| Media | Temperature |
|---|---|
| H₃PO₄, Wet-process phosphoric acid, H₂SO₄, HCl, HNO₃, Phosphorus-containing intermediates | 0°C -180°C |
| Project Location | |
Severe corrosion exists Media contain solids or crystals Tight shutoff is required Maintenance access is limited | |
