Adjustable Metal Tube High Pressure Multi Layer Steel Braid Burst Safety


Description


Designed for vibration damping and thermal expansion compensation, our flexible metal hose features precision-welded convolutions with low springback force, allowing tight-radius bending (3x OD) without kinking. The electropolished inner surface (Ra ≤ 0.8µm) ensures zero contamination for semiconductor, pharmaceutical, and ultra-high-purity (UHP) gas systems.

RFQ

1. Do you offer certified explosion-proof hoses?
Yes, our ATEX/IECEx Zone 0 certified hoses feature conductive liners (<10⁶ Ω/m) and flame-arresting construction per ISO 16852.


2. What's your minimum bending radius?
Depending on design, we achieve 3x hose diameter for static applications and 5x diameter for dynamic service - 30% tighter than industry averages.


3. How do you prevent hose failure from vibration?
Our proprietary braid patterns provide 82% vibration damping (ISO 10846-3 verified) with stainless steel wire optimized for fatigue resistance.


4. Can you make FDA-compliant hoses?
Our 316L-ELC sanitary hoses meet FDA 21 CFR 177.2600 with electropolished (Ra≤0.25μm) interiors and drainable tri-clamp connections.
