Metal hose is an important connection component in engineering technology. It is made of corrugated flexible pipe, mesh sleeve and joint.  It is used as compensation element, sealing element, connecting element and damping element in various gas transmission, infusion pipeline systems and length, temperature, position, and Angle compensation systems, and is applied in aerospace, petrochemical, mining electronics, mechanical shipbuilding, medical health, light textile electronics, energy construction and other fields. 

Metal hose made of austenitic stainless steel material or according to user requirements of the material manufacturing, has excellent softness, corrosion resistance, high temperature resistance (-235℃ ~ +450℃), high pressure resistance (up to 32MPa), in the pipeline can be connected in any direction,  Used for temperature compensation and absorption of vibration, reduce noise, change the direction of medium transportation, eliminate the mechanical displacement between pipes or pipes and equipment, double flange corrugated metal hose displacement, vibration of a variety of pumps, valves and other flexible joints are particularly suitable. 

Metal hose is the main pressure parts of the hose installed in the pressure line, while the bellows play a sheath role, according to the size of the pressure in the pipeline and the application place, can choose a layer or multiple layers of stainless steel wire or steel belt braid, the pressure range of the Dawn brand hose is generally PN0.6 -- 32.0Mpa.  Up to 42.0MPa.  Because the main parts of the production of hose material is made of austenitic stainless steel, thus to ensure the hose excellent temperature resistance and corrosion resistance, hose working temperature range is very wide, -196-600 degrees, the use of hose according to the corrosion of the pipeline through the medium selected suitable stainless steel brand, can ensure the corrosion resistance of the hose. 

Corrugated metal hose has good softness, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance and many other characteristics, it is relative to other hose (rubber, plastic hose) life is much higher, so it has higher comprehensive economic benefits.  With the development of modern industry, the demand of corrugated metal hose with high temperature and high pressure resistance is also increasing.  Application scope of hose: The delivery pipe with full flexibility is required to prevent vibration. It is suitable for steam, gas, air, heavy oil, petroleum, chemical drugs and so on.
