What tests do construction units of finished pressure vessels need to do?
Thread Content
The construction teacher's textbook introduces 1. Tower tests (pressure resistance test and air tightness test 2. Water filling test of large storage tanks 3. Pressure resistance test and leakage test of spherical tanks. As shown in the figure, what tests are required for this type of pressure vessel tank?
For this type of pressure vessel tank, the tests that the construction unit needs to do usually include the following:: 1. Withstand voltage test: Test whether the container can withstand the specified pressure and temperature conditions, and whether there are any safety hazards such as leakage and expansion. ； 2. System leakage test: Test the air tightness of the piping system to avoid gas leaks ； 3. Thermal stability test: Test the stability and durability of containers under high temperature conditions ； 4. Specification check: Check whether the size standards of the container meet the requirements ； 5. Electrical insulation strength test: Conduct insulation strength tests on the electrical devices inside the container to ensure safety and reliability. .

Nothing needs to be done for the on-site installation unit.

This post was last edited by hawkings on 2023-3-31 20:39 According to the current policy, for this kind of integrated pressure vessel, the construction unit needs to notify but not supervise the inspection. Since the test pressure of the pressure vessel is lower than that of the process pipeline, the container is generally isolated by a blind plate during the pressure test. The air tightness test and the corresponding process pipeline can be done together. For installation, please read TSG21-2016 for more details. Installation chapter in "Technical Safety Supervision Regulations for Stationary Pressure Vessels".
