High Temperature Braided Expansion Joint DN80 PN10 Stainless Steel Metal Hose
Flanged Metal Hose Product Introduction
Flanged metal hose is an industrial connection solution consisting of metal bellows, mesh sleeves and fittings that are highly efficient and versatile. Its main structure includes metal bellows, mesh sleeves and joints, of which metal bellows provide flexibility and corrosion resistance, mesh sleeves enhance protection, and joints are flanged to facilitate docking with various equipment.
Structure Features
- Metal bellows: Excellent flexibility and corrosion resistance, maintaining stable performance in complex working environments.
- Mesh sleeve: Reinforces and protects the bellows from deformation when subjected to external pressure.
- Joint: Flange connection ensures fast and reliable connection while reducing leakage risk.
Application Advantages
- High flexibility: Easily copes with complex pipe layouts and reduces installation difficulty.
- Strong corrosion resistance: Resists chemical erosion and adapts to harsh working environments.
- Stable connection: Flange design ensures tight, stable connections with minimal leakage risk.
- Easy maintenance: Simple structure allows for relatively easy maintenance and replacement.

Product Types of Metal Flexible Hose
Usage Scenarios
Flanged metal hoses are widely used in petrochemical, pharmaceutical, and food processing industries. Their ability to handle corrosive substances makes them superior to conventional rubber hoses in petrochemical applications. In pharmaceutical and food processing sectors, their corrosion resistance and ease of cleaning make them the preferred choice.
Usage Precautions
- The stainless steel hose bellows are made of chromium-nickel austenitic stainless steel - prevent pitting corrosion from nitrogen ions and dilute sulfuric acid.
- After hydraulic tests, prevent rust block impacts and chloride-containing sediment deposition to avoid corrosion and mechanical damage.
- During installation, protect from welding spatter and mechanical damage to prevent leakage.
- Follow safety procedures to prevent hose detachment or bursting from overpressure.
- Strictly follow the correct installation method as per provided guidelines.
