Flanged metal hoses are extensively used across multiple industries including petrochemical, pharmaceutical, and food processing. In petrochemical applications, they handle corrosive substances where conventional rubber hoses are inadequate. For pharmaceutical and food processing sectors, their corrosion resistance and ease of cleaning make them the preferred choice for maintaining product purity and safety standards.
- The chromium-nickel austenitic stainless steel construction requires protection against pitting corrosion from nitrogen ions and dilute sulfuric acid
- After hydraulic testing, prevent rust block impact and chloride-containing sediment deposition to avoid corrosion and mechanical damage
- During installation, protect the metal hose from welding spatter and mechanical damage to prevent leakage
- Follow safety protocols in sealed pipe systems to prevent hose detachment or bursting from overpressure
- Review installation examples thoroughly and adhere strictly to correct installation diagrams
