Burst pressure
The burst pressure is a technical term of the art , of a quality feature for pipes , hoses , tires , containers and pressure vessels , as well as for films , membranes , papers and cardboards represents. It is also a determining factor in the destruction of underground pipes for renovation purposes . The loaded elements fail when the bursting pressure is reached, which can cause an explosion in the event of a sudden failure . The bursting pressure is determined using a suitable test method and specified in k Pa or bar . It is usually many times higher than the permissible nominal pressure .
For foils, paper, cardboard and cardboard, the bursting pressure for the material specification is determined in accordance with DIN 53141 and specified in kPa.
The burst pressure tests are carried out in accordance with DIN ISO 2758. The material sample is clamped in a circle on a membrane, which arches under the action of pressure and causes the material sample to burst. The hydraulic pressure acting on the membrane during the bursting process is also the bursting pressure of the material to be examined.
Furthermore, the bursting pressure is a determining factor in the underground rehabilitation and destruction of old pipes, where the effect of a bursting body on the inner wall of the pipe destroys it and the pipes can be removed.
