Structure and properties of corrugated metal hose

Corrugated metal hose ( short hose ) is a modern industrial pipeline a high quality flexible pipe . It mainly consists of bellows, nets and joint components. Its inner tube is a spiral or annular waveform walled stainless steel bellows , bellows outer nets, is made of stainless steel wire or woven according to certain parameters . Hose Jic hydraulic fittings or flanges at both ends of the pipe joints with customers or flange mating .Bellows hose is made of very thin-walled stainless steel seamless or longitudinal weld precision plastic processing after forming . Because the elastic property of the bellows determine the contour hose has good flexibility and fatigue resistance , making it very easy to absorb deformation and cyclic loading various sports , especially in the piping system has the ability to compensate for a large amount of displacement . I plant in addition to the original hose sophisticated production equipment, recently introduced from Japan two high-precision , high-tech molded bellows automatic welding production lines, greatly improved the quality of the hose and the hose length is not produced limits , to meet the needs of long hose . Dawn brand hose nominal diameter range of DN4-800mm, length optional. Nets are installed in the pressure line hose main pressure parts , while the bellows from the sheath effect, according to the size of pipeline pressure and locations , you can select one or more layers of stainless steel wire or steel strip weaving, dawn brand hose pressure range is generally PN0.6-32.0Mpa. Up to 42.0MPa. The production of the main part of the material hose is the use of austenitic stainless steel , thus ensuring the hose excellent in heat resistance and corrosion resistance of the hose very wide temperature range , is -196-600 degrees to hose by pipelines through the media choose to apply corrosive stainless steel grades, the corrosion resistance of the hose can be guaranteed . Corrugated metal hose has good flexibility, fatigue resistance, high pressure, high temperature resistance, corrosion resistance , and many other features, it is relative to other hoses ( rubber, plastic hose ) much higher lifetime would therefore it also has a high overall economic efficiency . With the development of modern industry , for high temperature, high pressure hose corrugated metal demand is also getting bigger . Hose Scope: need fully flexible pipes, to prevent vibration premises piping for steam, gas , air, heavy oil, petroleum, chemical -pharmaceutical etc apply.
