*Product Introduction:

Metal hose (referred to as hose) is one of the highest quality flexible pipes in modern industrial pipelines. It is mainly composed of corrugated pipes, mesh sleeves, and joints. Its inner tube is a thin-walled stainless steel corrugated tube with a spiral or circular waveform, and the outer mesh of the corrugated tube is woven from stainless steel wire or steel strip according to predetermined parameters. The joints or flanges at both ends of the hose are compatible with the joints or flanges of the customer's pipeline. The mesh sleeve is the main pressure bearing component of the hose installed in the pressure pipeline, and also serves as a protective sheath for the corrugated pipe. Depending on the pressure in the pipeline and the application location, multiple layers of stainless steel wire or steel strip can be selected for weaving. The pressure range of the hose is generally PN0.6-32.0Mpa. Up to 42.0MPa. Due to the use of austenitic stainless steel as the main component in the production of hoses, excellent temperature and corrosion resistance of the hoses are ensured, and the working temperature range of the hoses is also covered Wide, ranging from -196 to 600 degrees, the hose used should be selected with the appropriate stainless steel * grade according to the corrosiveness of the medium through which the pipeline passes, in order to ensure the corrosion resistance of the hose. Scope of application of hose: It is suitable for conveying pipes that require sufficient flexibility to prevent piping in vibration areas, and is applicable to steam, gas, air, heavy oil, petroleum, chemical drugs, etc.

To ensure the safe operation of pipelines and solve displacement caused by settlement, our company has independently designed and developed a fully stainless steel material with a settlement universal absorption flexible hose. This product has high corrosion resistance, good flexibility, large settlement absorption, deformation displacement, and absorption of multiple combinations, deviation displacement, high temperature and low cold resistance, anti vibration and noise absorption, and long service life. This fundamentally solves the problem of multiple combination settlement deviation in rigid and plastic pipelines. This product is suitable for transporting oil, water (sewage), steam, and various liquid powder chemical raw material media, with a pressure vacuum of about 6.0MPa.

5、 Installation precautions:

1. When selecting metal hoses, for ease of installation, please try to use loose flange metal hoses with the * end as much as possible.

2. During welding operations at the construction site, the surface of metal hoses should be protected to prevent welding slag and arc ignition Metal hose.

3. Strict Twisted installation of metal hoses.

4. It should not be bent along the root of the metal hose Bend.

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

6. Strictly follow the installation diagram and install in the correct way. (See installation guide)

7. Strict Mechanical damage Flange sealing surface.

8. Do not use chlorine containing cleaning agents or steel wire brushes Dirt inside the metal hose.

In addition, there are * types of PTFE lined flexible rubber joint products to choose from, which are also good products for strong acid and alkali pipelines.
