✅ Structural composition of metal hose:

A typical metal hose consists of the following three parts:

Bellows body: mostly made of stainless steel, with spiral or annular corrugations, which is the core part of the hose flexibility.

Outer braided mesh (optional): woven with stainless steel wire or steel belt, used to enhance pressure bearing capacity and tensile strength.

Joint flange or threaded joint: standard interface for connecting other pipes or equipment, with various types (flange, clamp, welding, thread, etc.).

? Main features of metal hose:

1. High temperature and high pressure resistance

Stainless steel metal hose can work normally in the range of -196℃ to +600℃, and the pressure resistance can reach several megapascals (MPa) depending on the structure and material, suitable for steam, hot oil, hydraulic system and other working conditions.

2. Strong corrosion resistance

Using 304, 316, 316L, 321 and other stainless steel materials, it can resist the erosion of most acids, alkalis, salts, solvents, corrosive gases and other media, especially suitable for chemical, pharmaceutical, food and other industries.

3. Strong flexibility and compensation ability

It can play a compensatory role in the connection position of bending, twisting, and displacement changes, effectively relieve the stress caused by thermal expansion and contraction, mechanical displacement, vibration, etc. of the pipeline, and protect the safe operation of the system.

4. Reliable sealing performance

The corrugated structure is tightly combined with the metal body and is often used in high sealing requirements. It can prevent leakage and is suitable for the transmission of gas, liquid, vacuum, etc.

5. Anti-fatigue and long life

After reasonable design and manufacturing, high-quality metal hoses have excellent fatigue life and can be used for a long time under complex working conditions.

⚠️ Precautions for use:

The bending radius cannot be less than the design requirements, otherwise it is easy to cause fatigue damage;

Axial stretching and compression should be avoided during installation, and the connection should be in a natural state;

It is recommended to use a support structure or anti-vibration device under long-term high-frequency vibration conditions;

The material selection must match the conditions such as the medium being transported, working temperature, and pressure.

? Common application areas:

Boiler system: steam pipe, compensation pipe section;

Chemical/pharmaceutical industry: corrosion-resistant fluid transportation;

Gas/heating: metal gas pipe, water heater connection;

Semiconductor and vacuum industry: high-purity clean medium transmission;

Mechanical equipment connection: shock-absorbing flexible joint, hydraulic oil pipe;

Cable protection: metal hose covering the cable, tensile, compression, waterproof and rat-proof.
