Pressure cycle testing is a test performed to determine the durability of a material or system. This testing involves applying repetitive pressure cycles within a specified pressure range to simulate the exposure of the material or system to actual conditions of use. These tests are often used to evaluate the durability of components exposed to pressure, such as pipelines, plumbing systems, pressure vessels, valves, pump systems.

A pressure cycle tester is a device designed to perform these tests. These devices have a cycle that can apply pressure for a certain period of time within a certain pressure range and then release the pressure. Thanks to the adjustable number of cycles, a certain number of pressure cycles can be applied.

These devices are usually connected to a pressure source and test parameters such as pressure levels and cycle times can be adjusted via a control panel or computer. Pressure cycle testing devices are used to evaluate the resistance to pressure on the material or system and to detect possible failures or non-durability. These tests are widely used in areas such as product design, quality control and performance evaluation.
