The metal hose includes a stainless steel metal hose. The metal hose has inner and outer layers, and the inner tube, that is, the corrugated tube, is made of stainless steel, divided into 201, 304 and 316. The main difference between the two is the material of the outer steel wire braid. There are steel wires made of carbon steel and steel wires made of stainless steel. Theoretically speaking, carbon steel material is easy to rust, but the working pressure is not much different from stainless steel material. However, the quality of domestic carbon steel materials is very low and relatively few, so the price of carbon steel metal hoses is relatively cheap. Manufacturers of stainless steel braided metal hoses recommend buying stainless steel metal hoses. You can clearly state your needs with the provider.

Both are made of stainless steel corrugated pipes with one or more layers of steel wire or steel belt mesh sleeves, and the two ends are equipped with joints or flange heads, which are flexible components for conveying various media.

The main purpose:

  1. Transport corrosive chemical media. (For example: loading and unloading ammonia water, etc.)
  2. Conveying high temperature medium such as high temperature gas and hot oil. (For example: hot steam, heat transfer oil, etc.)
  3. Convey low temperature or ultra-low temperature medium. (E.g. liquid nitrogen)
  4. Transport water, steam, oil and other media under high temperature environment. (For example: water vapor system and hydraulic system in coking, steel making, continuous casting equipment)
  5. Pipelines that need to absorb vibration or eliminate noise. (For example: the inlet and outlet of the pump)

The main difference between the two is the material of the outer steel wire braid. There are steel wires made of carbon steel and steel wires made of stainless steel. Carbon steel is easy to rust, and the price is relatively cheap.

Metal hose structure: Metal hose is a high-quality flexible pipe in modern industrial pipelines. It is mainly composed of bellows, net sleeves and joints. Its inner tube is a thin-walled stainless steel corrugated tube with spiral or annular wave shape, and the outer mesh sleeve of the corrugated tube is woven by stainless steel wire or steel belt according to certain parameters. The joints or flanges at both ends of the hose are matched with the joints or flanges of the customer’s pipeline. Stainless steel braided metal hose manufacturers use austenitic stainless steel materials or materials according to user requirements, and can be connected in any direction in the pipeline to compensate for temperature and absorb vibration, reduce noise, change the direction of medium delivery, and eliminate inter-pipeline For mechanical displacement between pipes and equipment, double-flange metal corrugated hoses are particularly suitable for flexible joints of various pumps and valves with displacement and vibration.

The mesh sleeve is the main pressure-bearing part of the hose installed in the pressure pipeline, and it also acts as a sheath for the corrugated pipe. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wire or steel belt can be selected. For braiding, the pressure range of the hose is generally PN0.6-32.0Mpa. Up to 42.0MPa.

Since the main parts of the hose are made of austenitic stainless steel, the hose’s excellent temperature resistance and corrosion resistance are guaranteed. The hose’s operating temperature range is extremely wide, ranging from -196 to 600 degrees. The hose used The corrosion resistance of the hose can be ensured by selecting the applicable stainless steel grade according to the corrosiveness of the medium passing through the pipeline.

The scope of application of stainless steel braided metal hose manufacturers: a fully flexible delivery pipe is required to prevent vibration in the piping. It is suitable for steam, gas, air, heavy oil, petroleum, chemical drugs, etc.
