metal hose

Description :

Metal hose is the core flexible connector of industrial pipelines, with a standard structure of corrugated pipe (flexible body)+metal mesh sleeve (reinforced/anti expansion)+joint/flange (sealed connection); The mainstream material is 304/316 stainless steel, but there are also copper alloy and special alloy versions.

-Bellows: divided into circular and spiral shapes, providing bending and displacement compensation;

-Mesh cover: multi-layer steel wire/steel strip weaving, improving pressure resistance and impact resistance;

-Connectors: Threads, flanges, quick couplings to ensure sealing without leakage.

 2、 Core Performance and Advantages

1.  Strong flexibility: capable of bending at multiple angles, compensating for thermal expansion and contraction, equipment vibration, and installation deviations;

2.  Extreme environment resistance: 304/316 stainless steel is resistant to acid and alkali corrosion, and is suitable for temperatures ranging from -200 ℃ to+450 ℃ (special alloys may have higher temperatures);

3.  Pressure resistant seal: With multi-layer mesh support, it can withstand high pressure and ensure reliable joint sealing;

4.  Long service life, simple maintenance, more resistant to high temperature and aging than rubber hose.

3、 Common Categories

1.  According to ripples: circular (good elasticity, suitable for high-frequency vibration), spiral (high pressure, suitable for large diameters);

2.  According to usage: industrial medium transport type (chemical, power, ship), cable protection type (instrument, automation, building wiring), household type (shower hose, etc.).

4、 Typical application areas

Petrochemical, thermal power and nuclear power, aerospace, metallurgy, shipbuilding, building HVAC, water treatment, food and medicine; Commonly used for pump/compressor inlet and outlet, steam pipeline thermal compensation, vibration pipeline noise reduction, and narrow space pipeline connection.

5、 Key selection points

It is necessary to clarify the type of medium, temperature, working pressure, required compensation amount/bending radius, connection method (thread/flange), environmental corrosiveness, and service life requirements; Follow the GB/T 14525 standard
