Corrugated hose is a elastic element with corrugated pieces. It widely uses in apparatus and instrument as measure element for pressure. The wall is thin, so the sensitivity is better. While the pressure test range is several bar to dozens of Mpa. The open end is fixed, while the sealing end is a free state. Besides, it use a spring to improve the elasticity.
It extends along the hose with the pressure function. Then makes the free end produce a displacement. Further, the free end drive the pointer and indicate the pressure. Because the expand requires larger volume change, the response speed is not that fast. Thus it’s much better to measure low pressure.
Types of corrugated hose
Corrugated hose includes metal bellow, corrugated expansion section and metal hose. Metal corrugated hose is to compensate the hot distortion and absorb the shock. It’s a necessary part in petroleum, chemical, aerospace and power industry.
Then what’s the relationship between corrugated hose and metal hose?
The air tightness of corrugated hose is better than metal hose. Because it adopts entire material. But metal hose consists of hose body and outer spiral. Thus there may be light leakage problem. However, with the technology development, the air tightness will be much better.
Metal hose is suitable for steam, water, oil and industrial gas. Because it has great pressure and corrosion resistances. Besides, it plays an important roll in hot expansion and shock absorption. Because of the great property, metal hose is ideal for aerospace, petroleum and other applications.
OrientFlex has been worked on hoses since 2006. Besides these two hoses, we can offer you all the plastic hoses and rubber hoses. Thus you can find a proper hose here no matter which industry you work in. Contact us now and get the best quotation.
