Jiangsu PVC pipe the further development of industrialization, making the application of the scope of Chengdu bellows continue to expand. Because the bellows is under a certain pressure to work, and in the course of the work to bear the pressure and can not produce plastic deformation. So the pressure resistance bellows performance is an important bellows parameters.

The key is the stress analysis, that is, the maximum stress point of the bellows wall stress does not exceed the yield strength of the material, the pressure on the bellows will not reach its resistance to pressure. Because the same bellows in the same working conditions, by the external force than the internal force by the stability of good, therefore, by the external pressure when the maximum pressure than the internal pressure by the high pressure. The pressure value inside the bellows is known as the burst pressure at the start of blasting. Burst pressure is the maximum compressive strength of bellows parameters.

Therefore, when we use the bellows bellows should pay attention to the maximum pressure, our production will bring a lot of convenience.
