PTFE Lining Stainless Steel Metal Hose
DN15-DN150
This metal hose features a corrugated stainless steel core, overbraided with high-strength stainless steel wire, and lined with a smooth, seamless PTFE (Polytetrafluoroethylene) tube. The PTFE inner layer provides exceptional chemical resistance and a non-stick surface, while the stainless steel construction ensures high pressure tolerance and mechanical protection.

1. Key Features
Superior Corrosion Resistance: The PTFE liner resists nearly all aggressive chemicals, acids, alkalis, and solvents, making it suitable for harsh media handling.
Wide Temperature Range: Operates reliably from -60°C to +230°C (-76°F to +446°F), depending on pressure conditions.
Non-Stick Inner Surface: Prevents media adhesion and buildup, reducing fouling and facilitating easy cleaning.
High Flexibility and Fatigue Resistance: The corrugated core and braided reinforcement absorb vibration, accommodate thermal expansion, and allow dynamic bending in tight spaces.
High Pressure Rating: Stainless steel braiding significantly increases burst pressure and working pressure limits.
Anti-Permeation Design: The dense PTFE layer minimizes gas or liquid permeation, ensuring safe containment of volatile media.
2. Construction Materials
Inner Liner: Virgin or conductive PTFE (seamless, smooth bore).
Corrugated Core: AISI 304 or 316L stainless steel.
Braided Reinforcement: Single or double AISI 304 or 316L stainless steel wire.
End Fittings: Available in stainless steel, carbon steel, or other alloys, with various connection types (flanges, threads, quick couplings, etc.).
3. Typical Applications
Chemical and petrochemical transfer lines
Pharmaceutical and food processing (hygienic grade available)
Semiconductor and electronics manufacturing (ultra-pure media)
Steam, hot water, and thermal fluid systems
Corrosive gas and liquid handling in marine and industrial environments
Vibration dampening and misalignment compensation in pump and compressor connections
4. Technical Specifications (Reference Range)
Size Range: DN 15 – DN 150 (1/4” – 6”)
Working Pressure: Up to 40 MPa (depending on size and braid layers)
Burst Pressure: 4 times working pressure (minimum)
Bend Radius: Minimum static bend radius specified per size; dynamic applications require larger radii
5. Quality & Standards
Manufactured in compliance with international standards such as ISO, EN, or ASTM.
Hydrostatic and pneumatic testing available upon request.
Optional certifications: FDA-compliant PTFE, conductive/anti-static liner, high-purity cleaning and packaging.
6. Advantages Over Conventional Hoses
Outperforms rubber or plastic hoses in high-temperature and aggressive media conditions.
Offers longer service life with lower maintenance costs.
Provides a clean, contaminant-free flow path critical for sensitive processes.
