Construction and characteristics of stainless steel corrugated metal hose

Stainless steel corrugated metal hose (referred to as metal hose) is a flexible connecting pipe widely used in modern industrial pipelines. It consists mainly of a flexible body (corrugated pipe), a mesh body and various types of joints. Its inner tube is a thin-walled stainless steel corrugated tube with a spiral shape or a ring shape. The outer sleeve of the bellows is woven by stainless steel wire, steel wire braid or steel strip according to certain parameters. The joints at the ends of the metal hose can be fitted according to the user’s pipe or the joint of the equipment.

Construction of stainless steel corrugated metal hose:

The bellows part is a thin-walled seamless or longitudinal welded stainless steel thin-walled tube that has been shaped by high-precision plastic shaping. The elastic characteristics of the bellows profile determine the softness and fatigue resistance of the hose, and it is easy to absorb various motion deformations and cyclic loads, especially to compensate for the large displacement of the system. Since the main parts of the hose are made of austenitic stainless steel, the hose has excellent temperature resistance and corrosion resistance. The hose has a wide operating temperature range of -196-600 °C. Corrosion resistance of the hose can be ensured by selecting the applicable stainless steel grade according to the corrosiveness of the medium through the pipeline.

  1. The metal hose is made of 1Cr18Ni9Ti stainless steel as a whole and has strong corrosion resistance.
  2. The hose body is hydroformed by a thin-walled stainless steel pipe body, which has strong flexibility, flexibility, bending and vibration resistance, and enhanced protection of the woven mesh sleeve to make it have higher pressure bearing capacity.
  3. The connection at both ends of the hose can also be made in other ways than the thread and flange standards for easy connection and use.
  4. This product is not only suitable for use with rotary joints, but also widely used for flexible connections in a variety of fluid media delivery.

Stainless steel corrugated metal hose features:

It has good softness, fatigue resistance, high temperature resistance and corrosion resistance. It has a much higher life than other types of hoses (rubber and plastic hoses). With the development of modern industry, it has high temperature resistance and high pressure resistance. Corrosion-resistant stainless steel metal hoses will become more and more widely used.
