ATEX Certified Explosion Proof Ceramic Hose Lightweight Flexible Acid Resistant
Brief Introduction
Designed for extreme heat environments, this hose features a 99.5% alumina ceramic liner with a 316L stainless steel braid reinforcement, capable of continuous operation at 800°C (peak 1200°C). The low-thermal-conductivity ceramic layer minimizes heat transfer to external components, while the flexible metal sheath accommodates thermal expansion. Ideal for foundry slag handling, exhaust systems, and boiler feed applications. Compatible with molten salts, hot gases, and abrasive particulates. Standard sizes: DN25-DN400, with flanged or quick-connect fittings.

FAQ
1. What makes ceramic hose pipes superior to traditional rubber/steel hoses?
Our ceramic-lined hoses offer:
10-15x longer lifespan in abrasive applications (ASTM G65 verified)
Zero corrosion even with 98% acids or 50% alkalis
Weight savings up to 40% vs. steel pipes with equal pressure rating
2. What temperature/pressure limits do your hoses handle?
Standard range: -60°C to 800°C (peaks to 1200°C with special grades)
Pressure ratings: Up to 25MPa static, 15MPa dynamic (higher on request)
3. Are these hoses suitable for explosive environments?
Yes. We offer ATEX/IECEx-certified models with:
Conductive ceramic lining (<10⁶ Ω surface resistivity)
Anti-static outer layers (for Zone 1/21 hazardous areas)
4. What industries commonly use ceramic hose pipes?
Key applications include:
Mining: Slurry transport (80% solids)
Chemical: HF acid transfer (special ZrO₂ lining)
Steel: Molten slag handling (1300°C rated)
Food: CIP/SIP-compatible sanitary lines
5. How is the ceramic lining secured against detachment?
Our proprietary interlock system:
Mechanically bonds ceramic tiles to substrate
Withstands 5x standard bend radius without cracking
Passes 50,000+ flex cycles in validation tests
