2.discription
 
1)Stainless Steel Flexible Connectors contribute to the solution of vibration, noise, expansion and offset motion problems in piping systems.

2)Assemblies are designed for both high and low temperatures, as well as high pressure and full vacuum.
 3)The corrugated hose provides flexibility and prevents leakage, but has virtually no resistance to pressure thrust.

3)In a solid piping system, there is no external thrust, as the pressure on the projected area of the inside of the pipe is equalized by the two ends or bends in the pipe.

4)The force is taken by the pipe wall. Once a flexible hose is inserted, that capability is gone.
 
5)When fluid or gas pressure is applied to each corrugation, it tends to open axially, and this adds to the thrust of the pipe area multiplied by the line pressure.

6)As the thrust pulls on the anchored braid ends, the interwoven bias weave applies inward radial pressure to the corrugations as well. Pressure capability is largely a function of the braid.

7)When higher pressures are needed, it is seldom accomplished by thicker tubing as you would lose flexibility. It is most often accommodated by increasing the strength of the braid, using braid with heavier wire or tighter spacing described as Double or Triple Braid or just multiple braid layers.

8)While braid angle is an influence, a quick comparison of braid strength is to multiply the wire area by the total number of wires around the circumference.

3.Features

1)To absorb effectively he vibration, noise, thermal expansion from pipeline system
2)To resolve minor deviation because of piping connecting and eliminate the pipeline residual stress;
3)Applied to repeated motion in high temperature areas, good anti-fatigue performance;
4)Good flexibility, resistant to high temperature, resistant to corrosion.
 
4.Applications: The chemical industry, metallurgy, electricity, shipbuilding, construction and other industries
