Metal Hose

Metal hoses are widely used in industrial piping systems for the safe transfer of liquids, gases, and steam. Known for their flexibility, durability, and excellent resistance to extreme temperatures and corrosion, metal hoses provide a reliable solution for demanding industrial applications. Due to these advantages, metal hoses are widely used across various industries including machinery manufacturing, chemical processing, oil and gas, metallurgy, and food processing, ensuring safe, efficient, and reliable fluid transfer in critical applications.

Structure

Metal hose consists of three parts: inner corrugated metal tube, outer metal mesh and fitting connection. Inner part corrugated metal tube is the main body of metal hose, it plays the role of keeping hose flexibility character, outer metal mesh mainly bear the function of pressure-bearing, and fitting connector serves as a connection, different fitting connection is selected according to various connection requirement.

Pressure Bearing

Pressure bearing ability of metal hose always change from 18 bar to 120 bar. Metal hose is the mainly pressure bearing component that installed within pipeline transfer system, different braid layers such as 1 layer braid, 2 layer braid or multi-layer braid can be selected according to different pressure rating requirement or application scene. 

Advantage

Metal hose always takes raw material of austenitic stainless steel, therefore, it ensures the excellent high and low temperature resistance and corrosion resistance performance, it also has broad application range from low -196℃ up to 450℃, the stainless steel application grade is selected according to transfer medium corrosion situation of the metal hose.

• Metal hose totally adopt austenitic stainless steel, which lead to strong corrosion bearing capacity.
• Inner metal tube is made of thin-walled stainless steel which used hydroformed technology, which is of strong flexibility and seismic capability, outer coated braid layer enables it has higher pressure bearing ability.
• Both fitting connection of flexible metal hose has a variety of ways to connect, such as thread connection, flange connection and quick release connection.

Fitting Connection of Metal Hose

The function of fitting connection is to joint metal mesh and inner corrugated metal tube, at the mean time, fitting connection is also the medium for connecting other metal hose fitting. Material of the fitting connection is always the same as corrugated metal tube and metal mesh, most of them takes stainless steel as raw material. To reduce cost, many big size metal hose often takes carbon steel material to produce fitting connection under situation of transferring low extent corrosion medium . The sealing form of fitting connection always to be thread type, flange type and quick release type:

• Fitting connection size under 50mm always take thread type.
• Fitting connection size above 50mm often takes flange type.
• Quick release fitting connection always applied to fast connection situation.
