1. Structure: Stainless steel metal hoses are composed of a combination of stainless steel (1Cr18Ni9Ti) bellows, braided mesh, and connectors (flanges), or a combination of stainless steel bellows and connectors (flanges).

2. Function: Stainless steel metal hoses serve as compensators in connections between pipes and pipes, pipes and equipment, and equipment and equipment. Their flexibility compensates for positional deviations in the piping system caused by installation and accommodates the relative displacement required for the abnormal operation of the two endpoints. They also function to reduce vibration and eliminate noise.

3. Applications: ***Used in aerospace, aviation, metallurgy, petrochemicals, shipbuilding, building materials, power, thermal energy, gas, and other industries.

4. Features: Stainless steel metal hose products are characterized by light weight, small size, ***, flexible bending, and strong load-bearing capacity.

5. Specifications: Nominal outer diameter: 8-300 (mm) Wall thickness: 2-3 (mm) Temperature range: -196°C to 420°C

6. Introduction to three types of metal hoses:

Flange-connected stainless steel metal hose: One end is a flat welding flange, the other end is a loose flange, with the flange material being carbon steel. It is formed through *** plastic processing of extremely thin-walled seamless or welded stainless steel tubes.

Spherical (internal taper) joint stainless steel metal hose

Metal hoses are formed through *** plastic processing of extremely thin-walled seamless or welded stainless steel tubes. The elastic characteristics of the bellows profile endow the hose with excellent flexibility and fatigue resistance, making it easy to absorb various cyclic loads of motion deformation, especially compensating for large displacements in piping systems.

Pump-connected stainless steel metal hose

Installing a section of pump-connected hose at the inlet and outlet of a pump can reduce and absorb vibration and noise in the piping system, while also compensating for certain displacements, ensuring the system operates normally, purifying the working environment, and eliminating common issues such as aging and poor temperature resistance associated with previously used rubber hose connections.

II. Installation Precautions

1. When selecting a metal hose, choose one with a loose flange on one end for easier installation.

2. During welding operations on the construction site, protect the surface of the metal hose to prevent welding spatter and arcing from damaging the metal hose.

3. Do not install the metal hose in a twisted manner.

4. Avoid bending at the root of the metal hose and avoid sharp bends.

5. The medium conveyed must not be corrosive to the bellows material, and the chloride ion content in the medium should be ≤25 PPM.

6. Strictly follow the correct installation method as shown in the diagram. (Refer to the installation guide)

7. Do not mechanically damage the flange sealing surface.

8. Do not use chlorine-containing cleaners or wire brushes to remove dirt from the metal hose.
