The ultimate pressure test of corrosion resistant bursting discs is a key test for evaluating the performance of bursting discs under specific pressure conditions. As a safety pressure relief device, corrosion resistant bursting discs are widely used in the petroleum, chemical, electric power and other industries, and their performance is directly related to the safe operation of the equipment. By testing the ultimate pressure of the bursting disc, it can be ensured that it can accurately operate within the set pressure range to avoid equipment damage or safety accidents caused by overpressure or underpressure.
Testable items:
For corrosion resistant bursting discs, bursting pressure, bursting tolerance time, bursting disc thickness, material strength, sealing performance, corrosion resistance, temperature effect, fatigue life, bursting disc diameter, installation torque, bursting disc deformation, residual stress, bursting disc surface quality, bursting disc edge integrity, corrosion resistant bursting disc and flange fit, bursting disc rebound performance, bursting disc rupture mode, bursting disc material composition, bursting disc heat treatment effect, bursting disc coating performance.
Testing methods:
