effective area of corrugated pipe characterization of bellows converts pressure to a concentrated force ability, in the use of corrugated pipe pressure into concentrated force output, effective area is an important parameter.

corrugated work force balance instrument, the effective area of stability will directly affect the precision of the instrument. On this occasion not only requirements bellows have reasonable effective area, but also requires effective

area does not change according to the working conditions in the process of work. Effective area is an equivalent area, pressure axial force in this area will be equal. In general, with the increase of internal pressure, the effective area is smaller, corrugated pipe surface with

the increase of the external pressure, effective area is larger. Corrugated pipe under the action of external force or pressure differential, the volume variation and the corresponding effective length variation ratio of effective area called volume. Demand for the effective area of corrugated pipe and its calculation method depends on the purpose of the bellows. If the corrugated pipe for elastic seal or pipeline thermal compensation, the meaning of the effective area is only use

to calculate the corrugated pipe forming when the axial force and thrust in the system is used. Effective area of bellows worry there are some differences between calculated values and measured values. In general with special formula to calculate effective area of bellows, is can meet the need. When the corrugated pipe Yu Liping

scale instrument and the need to convert pressure can field, should be accurate to determine the effective area, requires a measurement one by one.
