Product Overview
The PTFE Lined Stainless Steel Braided Metal Hose from DevelFluid is the ultimate engineering solution for transporting highly corrosive chemicals, ultra-pure fluids, and high-temperature media. By combining a pressure-resistant stainless steel corrugated or smooth exterior with a chemically inert PTFE inner liner, this premium assembly offers both the rugged mechanical strength of metal and the exceptional corrosion resistance of fluoropolymers. It ensures maximum safety, zero leakage, and absolute purity for critical industrial processing lines.
Technical Advantages
- Universal Chemical Resistance: The integrated PTFE liner is virtually inert to all commercial chemicals, aggressive acids, organic solvents, and reactive bases, effectively preventing medium contamination and chemical corrosion.
- Non-Stick & Ultra-Clean: Features an extremely smooth, low-friction inner surface that completely prevents material buildup, crystallization, or bacterial growth, making it ideal for frequent media changes and sanitary processes.
- Excellent Temperature Stability: Engineered to maintain full structural integrity and flexibility across a demanding temperature range, operating reliably from -70°C up to +260°C.
- High-Pressure Safety: Reinforced with a high-tensile external stainless steel wire braid (SS304 or SS316L) to provide superior hoop strength, ensuring robust explosive-proof protection under high working pressures.
Applications
- Chemical & Petrochemical: Safe bulk transfer of aggressive chemicals, concentrated acids, corrosive liquors, and volatile hydrocarbons.
- Pharmaceutical & Biotech: Processing of ultra-pure medical fluids, sterile ingredients, and sanitary fluids requiring FDA-compliant materials.
- Food & Beverage: Handling of sticky food ingredients, cosmetic oils, pasteurized items, and frequent clean-in-place (CIP) operations.
- Power & Semi-conductor: Safe routing of ultra-pure deionized water, specialized gases, and thermal cycling media in cleanroom environments.
