Rectangular single-wave metal corrugated pipe is introduced
Rectangular single-wave metal bellows at work, under the action of the internal pressure along the length direction pipe elongation, the end is produced into a certain relationship of displacement with the pressure. End is the size of the pointer can be directly indicated pressure. Rectangular single-wave metal corrugated pipe is often combined with displacement sensor output for the power of pressure sensor, sometimes used as isolation components. Due to the extension of metal corrugated pipe for larger volume change, therefore its response speed is lower than the bellows.

Rectangular single-wave metal bellows instability phenomenon
Rectangular single-wave metal corrugated pipe elastic element under certain load instability phenomenon happens. Metal bellows instability with plane and column buckling instability of two cases. Plane instability is refers to the corrugated ring plate buckling, deformation, wave from uneven, such as: column buckling is corrugated at overall bending axis, deviated from the original straight line position. Whether it is a what kind of instability, is the metal corrugated pipe geometry lose the original equilibrium state, suddenly produce shape distortion phenomenon, instability of instantaneous components of stress often did not reach the yield strength of material, sometimes even less than the elastic limit.

Rectangular single-wave displacement of metal corrugated pipe allowed
To work in a state of compression metal corrugated compensator, it is the biggest compressive displacement: metal bellows under pressure, compressed into corrugated will have come into contact with each other each other between the maximal displacement value, also known as structure allows the maximal displacement, it is equal to the metal corrugated pipe free length and the difference between the lengths of the maximum compression.
Metal corrugated pipe does not produce plastic deformation case can get the biggest displacement called metal corrugated pipe allowed displacement.

Rectangular single-wave metal corrugated pipe resistance to pressure
Stress is a rectangular single-wave metal corrugated pipe resistance is an important parameter. Metal corrugated pipe at room temperature, the waveform does not occur plastic deformation on the maximum static pressure, can withstand the maximum resistance to pressure for the metal corrugated pipe in the general case, metal bellows is work under certain pressure, so it must withstand the pressure in the process of the whole work and do not produce plastic deformation.

Rectangular single-wave metal corrugated pipe product features
Rectangular single-wave metal corrugated pipe has the following features:
1, the metal corrugated pipe length can be arbitrary cutting according to the installation site.
2, metal bellows is crooked, so don't have to use all sorts of bend transition's at the corner of the building, make the installation more convenient and quick, and reduce costs.
3, metal corrugated pipe surface is covered a layer to prevent burning hose protection cover, good impact resistance to surface.
4, good security, each metal corrugated pipe before delivery for the tightness and pressure resistance experiment, for later use until a reliable guarantee.
5, flexible connection, according to the need can be based on non-metallic flat gasket sealing connection, also can use a metal ball cone hard seal connection.
