Heat exchanger hydrostatic leak test
Thread Content
The tubes of the heat exchanger are leaking, and it is necessary to locate the leaks during maintenance. It is planned to conduct a hydrostatic test on the shell side; the operating pressure on the equipment’s shell side is 4.1 MPa, with a design pressure of 5.6 MPa. The operating pressure on the tube side is 15 MPa, and the design pressure is 18 MPa. What pressure should be used for the hydrostatic test to detect leaks?
Check the as-built drawings; they show the hydrostatic test pressure. It is related to the design pressure, design temperature, and material.
If the shell side is pressurized according to the design specifications for leak detection and repair, what should be done if leaks still occur after it is put into operation?
Normally, the design should be worth 1.25 times that amount
