Hydraulic test is one of the most commonly used types of destructive testing conducted to verify the strength and density of vessels, pipelines, heat exchangers, pumps and other equipment operating under pressure, their parts and Assembly units. Hydraulic tests can be subjected to schemes of mechanical equipment Assembly and even the whole thermal network. Adopted in most countries in practice, all equipment, working under pressure, and subjected to a hydraulic test:
1) after manufacture by the manufacturer of the equipment or piping elements that are supplied on the installation;
2) after installation of equipment and pipelines;
3) in the operation of equipment and pipelines loaded by water pressure, steam or steam-water mixture.
Hydraulic testing is a necessary procedure, indicating the reliability of equipment and pipelines, operating under pressure, during the entire term of their service, which is extremely important, given the serious danger to life and health of people in the event of faults and accidents. In cases specified in design documentation for test article or state regulations and standards, allowed the replacement of the hydraulic testing by pneumatic testing using acoustic emission (AE) monitoring. The company Dynamics is able to conduct hydraulic and pneumatic testing with acoustic emission monitoring
