Flexible Metal Conduit Multiple Sizes Superior Corrosion Resistance Flexible Yet Strong
Description
Built for ore slurry, dredging, and abrasive media transfer, our wear-resistant metal hose combines hardened corrugations (HRC 55+) with replaceable ceramic liners. The external armored chains provide impact protection while the large-radius flow path reduces particle-induced erosion.

RFQ
1. Can you match competitor hose specifications?
We routinely reverse-engineer and improve upon existing designs, typically enhancing pressure ratings or cycle life by 20-30%.
2. What end connections are available?
All standard flange (ANSI/DIN/JIS), threaded (NPT/BSP), sanitary (SMS/3A), and quick-connect types, plus custom machined fittings.
3. How do you prevent electrostatic discharge?
Our conductive hoses feature carbon-loaded PTFE liners (<10⁶ Ω/m) with integrated grounding wires for hazardous area safety.
4. What support do you provide after sale?
We offer installation supervision, maintenance training, lifetime technical support, and a reconditioning program that cuts replacement costs by 50%.
