High Temp Hose Anti Oxidation For Extended Durability Lightweight Yet Sturdy Design
Description
Engineered for LNG transfer, liquid nitrogen, and cryogenic processing, our super-flexible metal hose features special austenitic stainless steel that maintains impact toughness below -196°C. The multi-layer vacuum insulation minimizes heat ingress while the anti-fracture helix design prevents brittle failure during thermal shocks.

RFQ
1. Can you make hoses for semiconductor gas systems?
Our UHP gas delivery hoses feature particle-free (<0.1μm) surfaces, ultra-low outgassing (<10⁻⁹ Torr·L/s), and SEMI F57 compliant construction.
2. What certifications do you hold?
We maintain PED, ASME B31.3, CRN, GOST, and other global pressure equipment certifications, with full material traceability.
3. How long do your hoses typically last?
Service life ranges from 3-5 years in severe duty (e.g., 25Hz pulsation) to 15+ years in moderate conditions, with predictive maintenance available.
4. Do you offer smart monitoring options?
Our IoT-enabled hoses integrate strain gauges and pressure/temperature sensors with wireless data transmission for condition monitoring.
