Ss304 Wire Mesh Stainless Steel Flexible Bellow Metal Flange Braided Hose

Metal hose is a flexible pipe component widely used in industry, construction, energy and other fields. It has the characteristics of pressure resistance, corrosion resistance and fatigue resistance.

Basic structure and composition
Bellows: core components, usually made of stainless steel (such as 304, 316L), with flexibility achieved through spiral or annular corrugated structures.

Braided mesh: a metal wire braid (such as stainless steel wire) covering the outer layer of the bellows to enhance pressure bearing capacity and resistance to mechanical damage.

Connectors: connectors at both ends, in various forms (threads, flanges, quick connectors, etc.), the material must match the bellows.

Main classification
By use:

General purpose: used for liquid and gas transportation.

High temperature/low temperature resistant: suitable for extreme temperature environments.

Corrosion resistant: used in corrosive environments such as chemical and marine.

By structure:

Single-layer/multi-layer bellows: multi-layer structure can withstand higher pressure.

With armor (braided mesh) or without armor: armor enhances compressive and tensile strength.

Application areas
Industrial pipelines: compensation for thermal expansion, shock absorption, connection equipment (such as pumps, valves).

Petrochemical/Chemical: transportation of acids, alkalis, oil and gas, etc.

Building HVAC: flexible connections in air conditioning and fire protection systems.

Aerospace/Automobile: fuel and hydraulic system pipelines.

Installation specifications:

Avoid twisting or excessive bending, the bending radius ≥ the design value.

Reserve length to compensate for thermal expansion and contraction.

Prevent the bellows from twisting when the joint is tightened.

Maintenance inspection:

Regularly check for leaks, mesh damage or bellows deformation.

Pay attention to surface cleaning in corrosive environments.
