Heavy Duty Ceramic Transfer Hose Dynamic Pressure 15Bar Leak Proof Flange Connections
Chemical Resistant Ceramic Lined Hose
A PTFE encapsulated ceramic core provides zero permeability to acids (HF-resistant grades available), alkalis, and solvents (compatible with 98% H2SO4, 50% NaOH). The corrosion-proof fluoropolymer outer jacket resists UV and chemical spills. Features non-stick surface for viscous media (e.g., polymers, adhesives). Operational range: -70°C to 260°C. Includes anti-static variants for flammable media transfer.

FAQ
1. How do I select the right ceramic grade?
Al₂O₃ (90-99.8%): General abrasion resistance
ZrO₂: Extreme acid/thermal shock (e.g., HF, 1500°C)
SiC: For ultra-high purity (semiconductor use)
2. What’s your lead time and warranty?
Standard sizes: 2-3 weeks
Custom designs: 4-6 weeks
Warranty: 5 years on ceramic lining
3. How do you ensure installation reliability?
We provide:
3D CAD mounting drawings
On-site technician support (optional)
Torque specs for all connection types
4. Can these hoses handle vacuum conditions?
Yes. Our helical wire-reinforced models:
Maintain shape under -0.95 bar vacuum
Kink resistant even at full suction
