With the increase of the scale of petrochemical plant, the volume of the container increases, the pressure vessel is more and more in the field assembly welding, and the blocking of the large diameter nozzle on the container is the difficult point of pressure test.

Test scope: import and export pressure vessel inspection includes the following: pressure vessel design review, operation of pressure vessel quality inspection, pressure vessel installation quality inspection, pressure vessel repair quality inspection, operation of pressure vessel quality inspection. In short, all can affect the safety operation of the pressure vessel project, are the scope of the test.
